Made by JM Fabrications this is For Mitsubishi Evo 7, 8, 9, Drag intake manifold for 1g throttle body, unpolished. Polished is a $50 extra option. If you would like the polished version please call us to order 319-665-6612.
These are hand made, TIG welded from high quality 6061 T6 aluminum. The flanges are all CNC machined and surfaced for precise fitment and a leak free seal. Each plenum is press bent to reduce the number of welds which will assure maximum strength under high boost applications. The plenum measures 16" long by 4 1/4" deep, the plenum also features a 1" taper design to even out the airflow, with a runner length of 5 1/4". Velocity stacks are CNC machined into each plenum bottom to improve airflow by 10-15%. The vacuum ports are placed on the underside of the plenum for a clean professional look. They are available unpolished or with a mirror like polish. Each manifold comes with a custom made SS dipstick tube. Some modifications to your upper intercooler pipes may be needed as this manifold sits down a lot lower then stock. If using the Accufab and other aftermarket throttle bodies, please note that the throttle cable and TPS sensors may need modifying. This manifold will also eliminate your EGR system so if you are not running a stand alone engine management most likely you will receive a CEL due to the eliminated EGR. An ECU flash is in the works to eliminate this error code. Expected gains can be anywhere from 10-45 HP depending upon your setup!
