Air is filtered through a 35% larger (when compared to the standard SF Intake) pre-oiled filter and routed to the MAF housing which is bolted to the airbox by way of a black anodized billet aluminum adapter

Note: You may need to source a new O-Ring (P/N 13717568031) and possibly a new C-Clip if yours are missing or damaged as they are not included with this kit
