3330 and 6097 work well. The Ik's also work well. I have the Ik24's which is 2 steps colder than stock, and I believe one step colder than the 3330's. Have worked for me for 5k miles boosting from 14 to 21 psi, gapped at .025 and DLI.

So far so good, for my next power level, Ill be using the Ik27's. If you dont mind changing them, get the 3330's. 1.50 a pop!
