Try 10 hp at the max, most likely less. Never go by the manufactures claim

nitrous_bob

yeah about 5 hp really

every +10 hp or -100 lbs is worth a tenth roughly...(at the early stages anyway)

other realistic gains are about 7 hp from an intake, 15-20 hp from an entire exhaust...header to tailpipe.

no where near what guys and companies claim.

I'd have to say bout 3 hp from a cai and 5-8 from exhaust...you get better throttle response from those two though.
