I just got some header for my car from the group buy, but im not sure on the size for the spark plug non-fouler. does any body know the size of it or part number?

I just did this trick on my MSP and it was 18mm. Just go to autozone and pick one up. There is a thread that tells you every thing you need to know in the MSP engine performance section.

Part 42002 for 3.99 at autozone. then a 1/2 inch drill bit will do the trick
