What size jet do you think I will have to run with the supertrapp idsII System on my 300? What air filter would you guys recommend for it also? Thanks in advance.

I was sent a 135(keihen) jet with my sparks. (stock was 122). That is for a stock motor with no airbox lid. Yours should be real close. Good luck.

Also I'd use a UNI over a K&N only because the UNI filters slightly better and flows almost as well as K&N.
