The Pusher 12VSMT 3.5" Mega Twin Intake System for your 94-98 Dodge 5.9L Cummins is the only twin ram style manifold on the market with a 3.5" inlet. This allows the Pusher manifold to be fed with an additional 37.7% more air over any of the other twin ram style manifolds with their stock sized 3" inlets. To ensure our manifold gets that extra air, we supply a 3.5" boost tube and couplers to match the factory 3.5" inter cooler outlet. Featuring a fully TIG welded construction with mandrel bent tubing, and 1/2" thick flanges, a 6061-T6 Aluminum 3/8" thick plenum plate, and 1/4" dipstick mount. All intakes come standard with two 1/8 inch NPT ports on the back for methanol/water injection, a boost gauge, etc.

The Pusher Mega Twin 12v manifolds are hydro boost compatible and retain the factory fuel filter housing.
