This listing is for a SET of NGK LTR7BHX (95605) Spark plugs for all Ecoboost/Coyote vehicles. These are pre-gapped and ready to install to our recommended spec for your vehicle based on fuel. We have tested multiple different sets of spark plugs and only offer the plugs that work best for the Ecoboost/Coyote application. 

• Price is for a complete set for your vehicle!

• Plugs are pre-gapped, do not attempt to change the gap!

• 13ft/lbs MAX TORQUE only, do not over torque any spark plugs!

• No Anti-seize or Dielectric Grease

• When selecting your fuel, the difference will be the gap. If you intend on running 91-92-93-94 AND E85 then you will purchase the 91-92-93-94-E30 Plugs!

• WE RECOMMEND FOR ALL VEHICLES, INCLUDING STOCK! YOU DO NOT NEED A TUNE TO RUN THESE PLUGS!

REPLACE EVERY 20,000-25,000 MILES FOR BEST PERFORMANCE!

For customers that solely run 91oct fuel we have seen better results on more knock-prone fuels like 91oct. If you are in Arizona, California, and Nevada we would prefer you to run these plugs over Iridium. This does not mean customers that run 93/E30/E85 cannot benefit from these plugs either. We are actually running these in our 400whp Fiesta ST (E50), and our 700whp Coyote F-150 (E85). 

Out of the box the NGK LTR7BHX (95605) Plugs come gapped at .038-.040". This is too large of a gap for any Ecoboost or Coyote engine and will cause breaking up under full throttle, rough idle, and misfire codes. NGK recommends not gapping the plugs .008" in either direction when using the traditional gap method. However we do not use the traditional gap method. We have a proprietary process that allows us to gap the plug without any added fatigue to the strap and without damaging the tip, and the plug retains this gap even after being heat cycled. This process happens over the course of 48 hours and all plugs are triple checked before shipping. 

Skip the headache of gapping your own plugs without the proper tools, and avoid the risk of having to toss your plugs in the bin and wasting $40+. Get plugs that arrive at your door ready to be installed, no messing around. 

 Benefits:

- Consistent Ignition Corrections

- 1-step colder than factory

- Greater knock prevention

- Ruthenium has a longer recommended change interval than Iridium
