Hi everyone, I felt like adding a few extra ponies to my car and was wondering what would be a good intake plenum. My stock plenum is leaking (gasket) so since I'll be at it, might as well swap it.

I'm looking for a very easy bolt-in intake plenum that will give my 305 some extra kick.

Anyone have any ideas on some good ones?

Thanks!

 

The plenum is not usually a "problem" the lower intake is more of a restriction. Most just port match to new runners. Bigger plenum helps at higher speeds, but everything needs upgraded, the exhaust is even more restrictive.

 

I have a nice exhaust from headers back. The lower intake...that's what I meant.

 

Edelbrock lower with AS&M or SLP or ported stock runners and the stock plenum seems to be the consensus for mild stuff/ Im wondering about the BBK piece if they ever get them in someones grubby paws
