Improved Spark with One Step Colder Heat Range than Stock

When you throw an aggressive tune and a wide range of F150 EcoBoost Performance parts at your very own 3.5L V6, you'll need a few bits of fine tuning to get your EcoBoosted motor running at its best. These NGK Iridium IX spark plugs are a nice upgrade that have a one step lower heat range than OEM for heavily modified and tuned trucks that still feature NGK's legendary reliability and performance. The Iridium IX plugs are built from the ground up to resist corrosion and fouling while providing improved spark, reliability, and versatility over your truck's factory spark plugs. This full set of six iridium spark plugs from NGK are an excellent choice for tuned vehicles that have wore out the welcome of the factory plugs.

High-Quality Iridium Tip and Corrosion-Resistant Design

The NGK Iridium IX spark plugs are named after their .6 mm laser-welded iridium tip that delivers a powerful arc while being highly resistant to corrosion and fouling. The insulator and electrode feature Trivalent metal plating that offers up vastly improved anti-seizure and anti-corrosion properties than traditional spark plugs. These plugs have a tapered electrode that reduces quenching while making regapping extremely simple.

Spark Plug Specifications:

Thread Size: 14mm
Heat Range: 7
Wrench Diameter: 5/8"

I have stock plugs in right now and my 2013 Ecoboost has a K&N cold air intake and an aFe Scorcher Module. Would these be the plugs I should put in and gap them at .30 or do you recommend something else?

Asked by: Rob - 10/7/2014

Generally, you'd only need these colder heat range plugs if you're heavily modified with bolt-ons and fairly aggressive tuning. If you plan on getting more parts and custom tuning down the road, then these plugs would still work. However, you'd probably be better off with NGK 6509s in the factory heat range, since your modifications are fairly basic.

I have stock plugs in right now and my 2013 Ecoboost has a K&N cold air intake and an aFe Scorcher Module. Would these be the plugs I should put in and gap them at .30 or do you recommend something else?

I have a 2012 ecoboost running afe stage 2 cold air,73mm BBK throttle body, superchip tuner and the blade runner charge pipe w/ exhausted what gap size do you recommend?

I have a 2013 ecoboost with banks monster exhaust, banks ram air cai, and banks tuner. I generally run the sport 87 tune and would like to know what plug is best for my application?

I have a 5 star tune on an SCT X4, 73mm throttle body, afe stage 2 cai, SW cat back and down pipes, TurboSmart BOVs, afe charge pipe, and am planning for afe hot side pipes and intercooler. Would this warrant stepping down to the 6510 plugs, or should I stick to the 6509?

I have a 13 f150 fx4 with k an n cai ..charge pipe..catless mak downpipe flowmaster super10...sct 91 octane race tune should I opt for the factory heat range plugs or these? Where do you draw the line on getting an improvement from these plugs?

Im running a 2011 Eco with a livernoise 93 custom tune, afe cai, and 4" exhaust. My tune claims upwards of 20-22psi of boost, am i in the range of needing the colder plugs or stick with factory? Also, what should they be gaped at for that high of boost?

Livernois 91 performance tune, offroad downpipes, 4 inch solo exhaust, 160 thermostat. Should I run these or another?

Will these spark plugs work for the Explorer Sport 3.5l Ecoboost? Thank you for all of the help.

Just purchased the Phase 2 package for my 2014 ecoboost. Which plugs should I grab?

Should I use these in my 2013 f150 ecoboost? I have a live wire tuner with 93 performance. And are they gapped at 0.30" out of the box?

I have a 13 f150 Eco with a k and n drop in cartridge, 4" afe catback exhaust and a sct x4 tuner running the 93 octane performance tune, with boost pressure at 22psi should I have these plugs? It does act a littler missy in the higher boost range?

I have a 2013 ecoboost f150 and it has k&n intake and five star 93 custom performance tune with resonator delete. Should I run these plugs or the 6509s?

I have a 2013 Ecoboost F150. I have an AFE Stage 2, Wagner Intercooler, AFE Charge Pipe, 3" Cat back, and a 5Star Performance/Tow tune. Would these plugs be of any benefit?

I have a 2011 EB F150 with Cavalli Turbos with turbosmart wastegates and blow off valves, afe stage 2 intake, built motor, exhaust and MPT 93 octane performance tune. Can this plug handle that or is there a better option..?

I have a 2014 with only bolt on changes. I got the 6509 plugs. What do i want the gap to be?

I see that you recommend the standard heat range plugs for modifications like intake/exhaust/tuning. Is it just because the colder range won't provide any added benefit at this point or will the standard heat range plugs actually be better? Thanks in advance.

Have you had anyone run a cooler plug than the NGK-6510 with success?

I’m guessing these are not pre gapped. Everyone is doing 30 is from what I’m understanding? Thanks!

I got a 2012 f150 eco boost with a k and n Intake and 73 mm throttle body. I’m going to add a tune but run the economy tune most of the time, also going to put a charge pipe on. Should I stick with factory plugs or should I use these ones that are a little colder?

I have a 17 3.5 with a injen intake, jet throttle body, magnaflow exhaust, FullRace Intercooler and piping, turbosmart bov, and plan to do down pipes this week before a custom Dyno. Would these be the plugs I want? Plan to upgrade turbos within next year as well..
