Upper intake
 

Are the upper intakes on the pi cars the same as the npi? What year does the pi start? has anybody tried porting the upper and lower intakes togather on pi and putting them on npi heads? what would the changes be?
Thanks
Matt

don't waste you time with those. they are a little different, but not enough to make a difference.

also DO NOT port a plastic lower. Its brittle enough as is.

the guys at fox lake are working on an all aluminum intake that should be done no earlier than this coming summer. That or the bullitt are the only ones worth the time.

C&L has a new upper, but it retains the plastic lower.
