High Flow Upper Intake Plenum

Our exclusive laser cut, hand-fabricated high-flow plenums for 6.2L and 6.5L diesels.  These come in multiple versions to support many different configurations.  Perfect for mechanical or electronic injection trucks with no extra fab work required to figure out where sensors will go. On most engines, especially those with upgraded turbos, you will instantly notice less cruise boost, lower EGT and lower IAT.  This all happens due to removing the restriction present in factory plenums so the turbocharger is not constantly pushing air up against a "wall". We can also add WMI ports (Water Methanol Injection) during fabrication to accommodate your 1/8" NPT nozzles!  If you don't have an aftermarket WMI kit then please disregard this option. Curved Outlet - 3" tubular connection to side-mount turbo with an integrated hose retention flange. Intake Base Plate Option: 6 bolt F Code 6.5L flange. 3/8" thick. Compatible with non-egr intake manifolds ONLY 2 bolt J Code 6.2L flange. Also fits non-e
