Highlights:

Full set of six OEM iridium spark plugs
Helps fix idle issues and spark blowout
Built with high-quality iridium tips
More resistant to fouling, blowout, and wear
Perfect for both tuned and stock F150s
Gap for tuned trucks: .028-.030"
Gap for stock trucks: .030-.032"

OE Replacement for Stock and Tuned EcoBoosts

Ford puts a lot of effort into the spark plugs that go into their latest generation of F150 engines, and their Motorcraft Iridium Spark Plugs are a surprisingly good choice for the 2011 to 2016 F150s rocking a powerful 3.5L EcoBoost V6. These spark plugs generate a clean, intense burn and come standard with an iridium tip that's highly resistant to fouling, corrosion, and general wear. These plugs are highly adaptable and can be used on bone-stock trucks and even aggressively tuned and heavily modified EcoBoost F150s when gapped down. These plugs come highly recommended by 5-Star Tuning for all of their performance tunes and are a great way to get your EcoBoost F150 back in tip-top running condition.

Can be Gapped Tighter for Tuned Trucks

This full set of six spark plugs come stock in newer 2013 to 2014 F150 EcoBoost trucks and provide excellent performance improvements for the 2011 to 2012 EcoBoosts thanks to their revised design, iridium tips, and slightly tighter gap. The plugs are simple, easy replacements for your truck's factory plugs and are an excellent way to squeeze improved performance out of your truck. For tuned vehicles, 5-Star recommends gapping each plug down to .030" for best performance.

Gapping for Stock Trucks: while a smaller gap is not required for bone-stock EcoBoosts, it's extremely important to make sure gapping is consistent across all six plugs before installation.

Plugs will need to be gapped and/or have their gaps checked before final installation.

13 F150 Platinum Ecoboost

Had rough idle, poor mpg, hesitation, and dirty tailpipe @ only 26K miles. Read about the widespread problems that ecoboost owners are having, and saw that cracked sparkplugs are usually the overlooked culprit. I checked ammy my plugs and had one crcked twice down the insulator. Stock gap was set at .034. My replacemnts arrived quickly, already gapped at .030 which is a setting that alot of owners (tuned and untuned) have good results with. Saved time and possibility of damage while gapping. I am very happy with this purchase.

2011 Ford F-150 FX 4 Ecoboost

Problem solved,sort of. The plugs fixed my mis- fire,power loss issue, but I think because of the old plug problem,I have developed cat issues.I was having the typical spark plug failure common to these engines,and of course, Ford will not address the root cause of the problem. It seems the inter cooler works entirely too well, and allows condensation vapor to accumulate in the heads, causing all sorts of havoc with the spark plugs. Which, in turn, mis- fire, and cause the catalytic converter to go bad. I have a tad over 95,000 on my truck, and aside from nearly getting killed several times when trying to pass, and having the engine go into, literally, a catatonic fit, I love it. The new plugs did remedy this, although power is not as new so I suspect the cats. Next up are condensate collector cans, and a new set of Y pipes, then all should be good. One note: The plug box says non adjustable gap. Don't believe it, just be careful. Mine were from .030-.034 out of the box. I gapped them all to .030 ( The plugs in the truck were anywhere from .037-.047 and this was the second set,from the dealer.) Bottom line: A quick quality fix for a very vexing problem.

Plugs arrived gapped to .30-.31. When I pulled the original plugs out, they were the same part number but gapped to .36-.37. Initially on starting, the truck idled extremely rough, consistently misfiring. After several minutes, it smoothed out, and no problems since. Guess the ECU had to do some re-learning. Unbelievably quieter, smoother idle than original.

2012 Ford F-150 Ecoboost 3.5l SuperCrew Pickup

I was due for my 60K service and as I was preparing to do the job, I bought my Motorcraft SP534-6 spark plugs from Stage 3. The 1st thing I want to say is, THANKS, the price was decent $39.00 usd for all 6 plugs! 2nd The plugs came gaped to .030 (this is a smaller gap than Ford recommends in the service manual) As soon as I started driving my truck, I noticed better response and my mileage went from 16.9 mpg(best) to 19.2 mpg. That has since averaged out at 18.2 mpg after about 5k miles. I have been dissatisfied with the gas mileage on this truck since the day I bought it! It never lived up to the advertised mileage, I always figured it was because of the 20 tires that came on it. I would and HAVE recommended these plugs to several of my friends who also drive Ecoboost trucks.

I've owned a couple turbo charged engines in my life and have found it best to just swap out the plugs as a maintenance more often than a regular gas engine. I personally do it once every 20000 miles.. seems after that, they start showing the wear.. these plugs are great, just the turbo charged gasoline engines seem to be demanding... about the same price as an oil change and an hour of your time and it'll save all kind of headaches

This product shipped in a timely fashion, had a issue with a couple of the spark plugs. I called them and Chris was real helpful and replaced them promptly. Once I installed them I could feel the power of these plugs, I have not noticed too much change in fuel economy but since I bought a used truck I wanted to do a full tune up. The only problem about these plugs is if you need a replacement plug you have to wait for them to be shipped to you since no auto parts store carries them in stock.

I gapped these plugs at 28 according to someone who posted on here and my mileage has certainly picked up by about 2 mpg plus it may even be more responsive than it ever was...... Prior to the plug change the truck had set an engine code. after the plug change and a day of driving, the truck cleared the code itself. I checked the old plugs and the gap had burned away to about 43 to 45 on all six plugs. This was a fairly straight forward and inexpensive fix. Stage 3 got me the plugs in just a couple of days.

After about a month or so of installing my Edge tuner, my truck started sputtering when I'd romp on the gas pedal. After doing some research online I found out tuners could cause that. I asked the guys at Stage 3 Motorsports and they confirmed that the stock spark plugs don't do good with tuners and I would need to upgrade. They recommended these motorcraft spark plugs. I asked my guy at the Ford dealership if they would install them on my next service and they gladly did. (He said great choice on the spark plugs by the way). Got my truck back and of course I had to test it out. Got on the highway, mashed on the gas, NO MORE SPUTTER! Right away I could tell the difference in the throttle response. Thanks for the fix guys.

My truck sputters at high rpm. Want to change out the spark plugs. Also read about cleaning intercooler? What is the proper way to do that? Any advice is greatly appreciated!

Asked by: Ryan - 10/22/2015

Before completely removing the intercooler for cleaning, you should just check and see if there's any oil residue on the inlets and outlet by popping off the hot side and cold side tubes. If you do see oil residue, then you may want to go ahead and clean out the intercooler. The best way is to just remove it from the truck, hose it out, and then run warm water and a mild soap (Dawn or Simple Green) through it. Then shake it out and let it dry for a bit before reinstallation.

I have a 2011ecoboost with afe stage2,inter cooler tubes, spacer, charge pipe, and a afe exhaust with no tune what spark plugs should i put. It shutters at high rpm?

Asked by: daniel - 5/12/2015

These spark plugs would work fine, however, you may want to pull your intercooler off of your truck and clean out any possible moisture buildup before you install new plugs.

Hi, if I buy these spark plugs can you pregap them ??? .030 gap ?? I am running a 93 performance custom tune... Thanks

Asked by: Kenny - 1/26/2015

The plugs should be gapped down to .030" out of the box, but it is important to check yourself due to the possibility of manufacturing variances and damage during shipping.

Just recently purchased a sct tuner w/5* tunes it recommends these plugs. My truck is a 14 w/ about 1500 miles on it I should have these plugs stock installed right or should I upgrade to handle the tunes ?

Asked by: Paul Williams - 4/6/2015

Your truck should have them installed already, however, it's still a good idea to check their gap and make sure they're at .030".

How long should one wait to put a tune on the truck after these plugs are put in?

Asked by: likmisak - 4/14/2015

You can technically throw a tune on as soon as you get the plugs in. However, I would personally take it for a test drive after you install the plugs to make sure everything's running decent.

I noticed the warning on the box now says Caution: Spark plug gap is not adjustable. Is this just thier way of saying that if you screw it up yourself try to get to .030, it's not their fault?

Asked by: NoCanGap? - 9/28/2016

It's more of an issue with the fact that these plugs have iridium tips, and you have to be extremely careful when gapping them. A lot of folks gap plugs by wedging a coin-style gap tool between the tip and electrode and just bending the electrode into place or tapping the electrode against a flat surface. However, iridium is very brittle, and is easily damaged by these methods. We recommend gently gapping the electrode with either a wire-tip gap tool or with a pair of pliers.

What plug is better to run the sp-534 or the sp-542?

Asked by: Brian Mccleary - 7/31/2017

That's dependent on the truck. The SP-542s are recommended for 2.7L EcoBoosts. The SP-534s are generally recommended for the 2011-2016 F150 3.5L EcoBoosts.

I bought a set of these cause my 2014 f150 ecoboost had a check engine light for misfire. Changed them out, old ones had spent to .042+. Spaced the new ones to .032, no more misfires and the truck runs good but I lost 1-1.5mpg... why?

Asked by: Pisarchuk - 12/10/2017

It's likely your truck just needs to complete a drive cycle after your plug change to show normalized fuel economy measurements. You can speed the process up with a KAM reset on your truck's PCM.

I replaced the stock plugs at 60k as I had bad stutter under load and rough idle. Truck idles and runs like a gem, but now I've lost 2mpg and it almost feels like I lost some boost as well. How is this possible, is there something I need to do, or something I did incorrectly?

Asked by: Jason - 1/25/2016

Your truck's PCM and transmission may just be going through their "relearning" processes, which can sometimes cause subpar performance. You may want to talk to your tuner of choice and verify where they want the spark plug gaps, as that can sometimes cause issues as well. If your problems persist or you need further troubleshooting, please call us directly at 1-877-578-2433.

Do you recommend gapping these plugs to .030" even for a stock 2012 Ecoboost?

Asked by: Blake - 4/28/2016

Gapping them that low will be fine. The recommended maximum gap is .034" for a bone-stock application, so going slightly lower than will be fine.

Asked by: Helmut - 6/28/2016

Additional shipping charges, taxes, and duties will be added for Canadian customers, but the price would still likely be much less than $29 a plug. That being said, most chain automotive stores also carry Motorcraft spark plugs, so you may want to call around locally.

I have a 2015 3.5L ecoboost with a tune, cai, afe tb spacer and sometimes when I lay in to the throttle I will get somewhat of a hesitation and you can hear something click/knock in the engine would a new set of these plugs take care of this issue or do you have any idea what would cause that ? I have about 13,000 miles on it

Asked by: KyleP - 10/30/2016

You likely wouldn't need to get new plugs, since your truck should have SP-534s from the factory. However, you likely do need to regap your current spark plugs to .028" to .030" to ensure that you're not having issues with spark blowout. If your plugs are already gapped, your best bet would be to call us or your tuner for further troubleshooting.

Asked by: MARLOWE - 11/20/2017

The 2015 F150 3.5L EcoBoosts came with SP-534s from the factory. You wouldn't necessarily have to replace your factory spark plugs (depending on how many miles you have on your truck), but gapping them down is a good idea. We don't have a specific intercooler cleaning video, but we do have an intercooler install/removal video here.

My truck is starting to shudder a bit when idling. From what I've read, the spark plugs could be the culprit, even at 36,000 miles. What is the difference between this plug and the SP-534, which is listed in my manual for the 2016 3.5 EcoBoost? Vehicle is 2016 F-150 King Ranch 4WD.

Asked by: Marcus - 3/12/2019

The SP-534s were superseded this year to the SP-580s. The SP-580s are an iridium plug like the SP-534s, but with a tighter gap out of the box than the SP-534s. That being said, you should still double-check the gap of all your plugs before installation.
