Just wanted some suggestions on an inexpensive plug that could substitute for stock. My plugs are starting to foul i believe, and have a dyno session tomorrow, and am not sure if i can get stock plugs in time, thanks lmk

 

i use the bosch 4227, they work great for me. I know a few people here havnt had much luck w/ these, but i have. They are cheap, and i change them every other oil change.

 

Stock... I waisted my money on Iridiums . stock plugs are best in my opinion

 

I run them on my boosted car... never had any problems... two sets, bout 40k miles... they will go in my 13:1 ITR... esp since they are a "wear item"... at $1.99 who can bitch?

ps Think Jeff of IB/IR has some back to back dyno runs on his site showing that the bosch 4227's can't be beat bang for the buck...

...that's for a high compression or forced induction application by the way... might probably be too cold a plug for an OE compression engine...

 

i went with champion rc12mc4, made 2whp over my 7k mileage stock ngks on the dyno
