re: delco sucks ass

:thumbup: I've got 41-948 Delcos in my truck. What's the part number for those Bosch plugs? I found an NGK copper plug that crosses to mine. Will that work, ya think?

Okay, wait......I have the platinum +4's, but if I switched to a .040 gap regular tipped platinum it would be a big difference?? I need to get some 8 mm wires too........bah, this truck is just taking money from me left and right, its all I spend money on anymore.....I want it faster, better looking, more reliable, and pimp as hell...so whatever....

I never knew a spark plug gapping would make a difference, I alwasy threw them in gapped at what the factory told me to gap it
