I found a deal that I can't pass up on a typhoon intake for a 1999 -2004 mustang. The first question is can I bolt this to my npi heads on my 98 via the way everyone is saying it can be done with a stock pi intake? Second if I change heads and cams to the standard pi's how much more hp will I get from it. I seen that a full pi swap brings about 40-50 rwhp. And I assume 20 or so is from the intake. The description on the typhoon says a dyno proven 20+hp. So I am also wondering is it worth it to change the heads and cams for only 20 hp?

 

Well you won't see the full 20+ hp unless you have all the supporting mods which would be , upgrade mass air , throttle boby, heads and Cam!!!! ...
