I have the K&N Aircharger, which by the looks of it on the K&N site is identicle. maybe they decided to call all their airchargers 'Fuel Injection Performance Kits' instead? Theyre the same design, right down to external IAT sensor location. I must say this intake was one of the most noticable increases in power but heh... i dunno about 26hp! Of all the intakes produced for us im pretty sure this one comes with the biggest filter, its a 6" diameter base tapered to 5" top and is 6.5" long, with more filter material at the end instead of just a rubber cap. 3" maf adaptor. The heat shield is nice but rattles against something at wot... i bet i could adjust that tho.
