Ok TBI guys what spark plugs are u running?
What are you running and how do you like them? Right now I am running Bosch Platinums and I'm swapping them out cause I dont like them. I was thinking of going with AC Delcos but I want to get your guy's inputs.

im running accel shortys with msd 8.8, 90 degree boots.....i got tired of my headers having a cookout 
if your running an msd box make sure you read the book that came with it it tells you what gap to run....i dont worry about temp range i just buy standard plug...or you can call msd they will tell ya what to gap it ......

Regular ole' AC Delco....hey, i've got a set of Bosch Platnums in a box never used if anyone wants to buy em for cheap. I really wasn't gonna even attempt to seel em, but they seem to be pretty popular among the TBI guys.

I got the AC Delco rapid fires because they were only like $7 more than the normal ones from carparts.com. Eh, I'd rather have the money in my pocket. Ill use normal Delcos next time.
