I was reading up on the stillen s/c kit and it says that you have to replace your plugs with 1 step cooler plugs. I'm curious what effect that has? Should this be done regardless what f/i system you with or is it just simply with the stillen kit?

Any force induction I do recomend cooler plugs NGK LFR6AIX-11 if you need some I have some in stock just shoot me a PM

 

I'm still curious why though. What do they provide vs. oem plugs...

A “cold” plug transfers heat rapidly from its firing end into the cooling system and is used to avoid core nose heat saturation where combustion-chamber or cylinder-head temperatures are relatively high. A “hot” plug has a slower heat transfer rate and is used to avoid fouling under relatively low chamber or head temperatures. What’s confusing is that a “hotter” (higher performance level) engine requires a colder plug because more power equals higher cylinder temperatures.

 

^^^nicely put^^^

With forced induction, at WOT, your engine is experiencing much more cylinder pressure and heat, which can lead to detonation. A hotter plug can contribute to this, so most people will run a slightly colder plug.

NA cars can run standard temp plugs without any issues.

 

Thank you.
