IMHO buying an aftermarket intake/filter is the equivalent to what I was doing 25 years ago... "Flipping the 'breather." It made an evil noise at WOT, but that was all it did. Oh, and it was a fire hazard if the engine backfired!
If Magnacharger thought that the supercharger kit needed an aftermarket air cleaner/filter they would have included it in the kit.
If you bolted on all the crap that’s available as aftermarket “performance” parts on your truck (and the manufacturers claims of HP gain were true) – Your engine would end up making 5,000 HP!
The best thing most of these intakes/filters do is to separate you from your money.
