93 TT spark plugs
Greetings all, use to be an old member (Only lipless NA I think, if you remember such a car) and now I just picked up a TT. Looked all around and such and just want to clarify. dual-intake-filter-baffle-fab-resolves- ... 32611.html Says to upgrade from the 5B-11B to 6B-11B even though psi is under 14ish? Advance auto parts has a set of 5B for $50 last day today, so just want to make sure on the correct ones to get. Thank you!

You would even be fine with factory NGK spark plugs, especially at that psi. I dont have the ngk part number on hand.

PFR6B-11B if running stock boost. NGK BKR7EIX if running up to 16lbs of boost. This is what SpecialtyZ recommends. Going with the iridiums ironed out the last of my issues trying to run 12-14PSI at the time.

Stick with the 6B. Regap them to .035". I know some people might argue but I just did mine and engine idles way smoother and faster pick up.
