the Official "NA Tuning" thread
Looks like we already got some with more power than 2qk4u and version_jdm... and iwht only 2 mods! Also what plugs do you guys use? I heard going one step colder is better? Any ideas?

oh i see... still a good read with usefull information, I also think that guys car with some mods and a single exhaust would still surpass the 230rwhp mark on a normal dyno... So what do you guys thinks about the spark plugs and getting colder plugs?

im not sure i understand the colder plugs...
A basic rule of thumb that I was taught by my dad years ago is for every additional 50 horsepower above your baseline, you should go one stage colder on your plugs.
Colder plugs are exactly what the sound like they are...the spark they produce is at a lower temperature than the next heat range up.
As with running higher octane fuels to reduce detonation and get a better flame front, colder plugs work in the same manner, but to compliment the higher octane fuel, not replace it. Since most of us run 93 octane already, it's not feasable or affordable for us to step up in octane once we're 50 hp higher than we started...colder plugs will help that 93 octane flame front burn more even and completely, thus deriving more power from the explosion and helping your engine run smoother and more powerful (slightly).
Basically, in my case, I started with 186 at the rear. I'm not switching to colder plugs until I'm at 236 at the rear (hopefully my ITB's will get me there.)
