Extract more power out of your 420A-powered DSM with our aluminum intake manifold plenum upgrade. Simply remove the stock restrictive upper plenum from the lower runners and bolt on our high-flow plenum for an immediate increase in horsepower and torque. Maintains use of the lower runner section - optionally port and polish your runners for additional power gains.

Specifically designed and tested for mild to moderately boosted engines using small and mid-frame sized turbochargers, although great gains are also being reported by customers with naturally aspirated engines. Power gains are always dependent upon the engine combination and tune up, but testing on our turbocharged shop cars have indicated only a 0.5-1% loss of low-load (idle/cruising) efficiency while easily picking up 3-5% during spool-up and observed increases of 5-10% at high-load wide open throttle boosted conditions. Horsepower gains typically range from 10-50 HP.
