    Did you install the engine yourself? If so, just refer to the manual for that motor. If you didn't install it yourself, ask the guys that did, and test their customer service. :D

    if your boosting..you will need to set the gap smaller.....

    I've heard that a 0.020 gap is fine for boost, I've tryed it and it worked wonders...the reason they say to keep the gap that small it to help keep the spark from blowing out....when you really need it. Unless you have an MSD system, then the gap should be small.

    if it's NGK's then it's already gapped from the factory.
