NA spark plugs in my TT

[z3290dett]

i was checking my spark plugs and i found na plugs... would this cause a major power loss? i know tt plugsare a little longer.

they would cause issues like running rough and some power loss but I'm not sure about a major power loss. Major power loss is usually things like vacuum leaks, boost leak, blown turbo seals, etc. You should definitely put the right plugs in though and see what happens.

Definitely not a good thing. Get some NGK PFR6B11-6B and be done with it. Takes maybe 30 minutes to swap the plugs. NA plugs are too long for a TT, by about 0.15".
