This Anderson Naturally Aspirated Power Pipe® is designed for Pro-M 77/80 Long Style meter on 1986-1993 Mustang 5.0L applications. Anderson Power Pies feature Mandrel bent 4" Ceramic coated (inside and out) pipe that puts the mass air and air cleaner in the inner fenderwell for a cooler intake charge for added H.P. Additional benefits of the Power Pipe is better driveability for Mustangs with bigger profile camshafts.
AFM Normally Aspirated Power Pipes were developed because of the need for higher volume, better flowing intake pipes needed with the higher RPM 4.6/5.0 and the bigger cubic inch 347/408. With the volume of air these engines need, the small factory rippled intake pipes are too restrictive and the cold air intake pipes are too small of volume. They rely on the cooler intake charge to gain H.P., which cannot be chassis Dyno tested. AFM dyno's each Power Pipe® to verify H.P. gains. The mass air is in the inner fenderwell, but we do not rely on the cooler intake to make the extra H.P. We do it in design and testing.
