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.

These plugs shipped insanely quick!, made a huge difference on my 60k mile ecoboost. You don't really notice how much power the stock plugs were missing until you install a set of these bad boys!! Can't say enough good things! Thanks James

If you get yourself a SCT likewise, pick up a set of these. They came perfectly gapped to .030 and easy to install. I'm running the 91 octane tune and making 21.9 lbs of boost. My truck is bad-fast!

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 had a huge misfire problem at high rpms but after reading around a bit I discovered that it was my plugs and stage 3 had the ones I needed. The misfire is gone and my truck is back to perfection.

I have no idea if mine were different than all other reviews but they were no where near gapped at .030 out the box. They ranged from .034 to .036, but were easy gapped down to a tight .029/.030. Other than that fast shipping, actually beat my tune here lol

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 solved my problem. Truck had what I though was a transmission shutter at 70mph, scanned the computer and got codes for misfires on 1 and 5!!! New plugs went in in 20 minutes, and all my power is back. Smooth and powerful acceleration is back. Fuel economy improved. Now I just need to save up and get that stage 3 performance kit!!

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.

FYI.... These are stamped with NGK part number on the base and made in Japan... So it appears NGK makes all the plugs for the truck. Buy whatever is less expensive.. Had one misfire the other day and replaced all plugs. Insulator was cracked from top to bottom on both sides of one plug... Gap was huge on all plugs (Excessive wear?). I have just under 37,000 miles on truck. Cheers!

I ordered these plugs based on previous reviews. I put them in a stock ecoboost with 76k miles experiencing a hard acceleration skip. It corrected this problem. Plugs came gapped around .035 and I re-gapped them to .030. I was shocked to see the ones I took out were anywhere from .042-.048. Made a huge difference with these new plugs gapped correctly. Quick shipping from stage 3 and another quality product as well!

Great product. Only place I could find that sells the plugs already gapped to .030. There was a bit of variance from .029-.031, but not an issue. The plugs were packed well and protected to minimize damage with shipping. I would highly recommend. No issues after installation. Truck started right up. Noticed a change in power immediately, fuel economy slowly improved as well over the first 1500 miles since install. Will be returning for future purchases.
