we need to make this a sticky on the forced induction page because I still get confused on which plugs are good to use and what we should gap them on.

Im currently using the NGK Iridiums but Im thinking about switching back to the heat range 7 "4644"

what are a list of plugs that are compatible with our cars and what the gap range should be set to insure proper firing when boosting at certain levels? I would love to boost 15 pounds but the misfire is killing me.

im about to buy the 4644 heat range 7

 

steven, dont know if your getting these BKR7E (4644) NGK v-power but ebay has them for $10.00 shipped. Just letting yall know.

 

Umm... JUST GO TO NAPA!!! there like... 1.30 each! omg.
local store might not have them. but the local warehouse will.. so go get 8 for cheap and keep 4 as spares..

i keep 4 spares with me at all times incase i foil a plug or some other issue. also keep extra coilpack and wires to. (but thats like when i go to the track) and i also bring an extra axle and fuel and couplers and clamps.. just incase.. just started to make a collection of things that have broken or gone missing when making a pass.. so now i just bring it with me to the track just incase. LOL

 

well I just ordered some from ebay for 8.85 for a 4 pack, I guess I will head up to napa tomorrow morning and pick some up so I can make the swap.
