Yeah I blew mine twice and replaced them each time. Of course I was running clear of 21psi at the time with 15% overdrive on the supercharger and an unbelievable amount of timing advance. Outran a stock 03 Cobra... made me happy :-) Now Im running a more conservative 10% overdrive and milder timing but still running high 13s which isnt bad for a 4100 pound car

Why would he have plugged the VTEC???
