This Site Might Help You. RE: which cold air intake produces most hp.? 1998 Chevy K1500 V8 5.7L
No cold air intake anywhere is gonna gain you 50 HP Rule of thumb is air inlet temp is worth 1% power gain for each 10* cooler the air is Most aftermarket kits will gain you 5-10 HP at best. The plumbing still gets heated in the engine bay. A racer's setup might gain 10-20 HP but thats a cold air setup thats wraped in heat sheild, inlet ducted to a hood scoop, etc
