This auction is for an AFM 4" PowerPipe for a '79-93 5.0L (AF-0101C) or with a Vortech (may fit some Paxton models also) supercharger. This pipe increases horsepower by reducing the pressure of incoming air into the supercharger and thus allowing it to create more pressure to the engine. Typically, a boost increase of 2-3 psi will be gained. AF-0101C$249.95 www.realspeedauto.com Ph.631-563-7325 All parts listed are for the Ford Mustang unless otherwise noted.
