I don't know how well your Z knowledge is but the above NGK that Lets Drift recommend is wrong. That plug is sub par for his stock motor/turbo Z. Did you know that R7EIX-R8EIX-R9EIX spark plug tip is shorter then the OEM NGK plug, PFR6B-11B? Do you know how much shorter it is? It's about a 1/4" shorter then the OEM NGK plug. On a TT head the tip is barely exposed to the combustion chamber and the results would be back fire and a loss of HP (~10-15 hp according to my dyno back in the days) but the car will still run. I've done this long ago and it's in the tt.net SEARCH but who cares when we have someone like you to encourage the wrong info and pat the back of the people who give the wrong answer. BTW, all this could have been done with if Emerald just plugged in the the key words in the SEARCH feature that I linked him to. I practically gave him the info he needed.
