tpi air foil
I was wondering if those air foils for a TPI intake are worth it and if they give you the gains they say they do.

I can see that at max flow it should have some advantages, and it won't hurt anything either. If the price is right I'd say get it. I put one on mine, paid like fifty bucks for it several years ago, don't really know if it did anything or not.

Don't remember the test but the one from Holley actually works the best and does give some power. I have a TPIS unit myself.
