I'm going to be getting a set of hedman 68470 shorty headers and 17478 y pipe. I was ready that I should use a shorty plug with these for more clearance. I was wondering what plug you all were useing (part #'s please)?

Also just a secondary question do these require o2 bungs to be welded in or are they already in the collectors?

 

i have the same set up on my car . (except headers are 68478 HTC coating) regular plugs are fine , stock plug wires are not . i have MSD wire kit #31229 with 90 degree boots on each end . works great for me . bung for O2 will need to be added . i put mine on drivers side of "Y" pipe just below collector . works great for me (no wire splices) . anyway , i like my set-up . good luck .

 

yeah deffinately run the 90 degree spark plug wires. and like Uncle said the stock plugs should work good.

 

Thanks guys that exactly what I needed to know... I'll post up once i get them installed

 

That is what we are here for. To try and help eachother. And to not waste anyone's money haha.
