Hey guys are these cold air intakes im seeing on EBay any good or worth buying? Theres not much to a cold air intake kit so will these kits I see for $30-$40 provide better air flow than the stock setup? From looking at the kits they look almost identical to a K&N setup minus the K&N stickers and unique K&N filter. Has anybody experimented with these kits?
