An easy 1" from the end of the plug to the rear tube. These are the std length NGK's - shorty plugs whould be even better. I think this would be VERY acceptable.

The frt plugs are even better cause the tube angles away from the plug more.


Heck, I'd be inclinde to RUN these on my car if I had them coated! Maybe I should save $500 and cancel the TTI's?
