What's a good aftermarket intake

RustyRatRod said
Yes. There are three Performer intakes for the small block. The Performer, the Performer RPM and the Performer RPM Air Gap. Each one gets more expensive.....but can make more power. I believe you would be happy with a good used Performer.

Yep. Each steps up in rpm band. The Performer works good from idle to around 5500.
