Designed for 1992 & later 5.2L (318 c.i.d.) and 1993 & later 5.9L (360 c.i.d.) Chrysler Magnum V8's, the RPM Air-Gap manifold allows the use of a carburettor on these originally fuel-injected engines for use in early muscle cars and street rods. This dual-plane manifold design incorporates the same race-winning Air-Gap technology that's been used on our Victor Series competition intakes for years for outstanding performance in the 1500 to 6500 rpm range. The Air-Gap design features an open air space that separates the runners from the hot engine oil resulting in a cooler, denser charge for more power. Match with Performer RPM Magnum cylinder heads ED61779 for maximum performance.
