Time to upgrade your 3 rotor like never before!!

• Material: 6061-T6 CNC machined aluminum
• This one-of-a-kind plenum is designed to maximize off boost power and broaden the torque curve to achieve amazing low boost power capabilities and ensure fantastic drivability throughout the entire powerband. 
• This part features a unique multi-part design that utilizes the stock 20b Cosmo upper intake manifold, which is modified to have multi-length intake port geometry for increased low rpm off boost power characteristics. It is then welded to a flange that bolts to the new billet plenum which allows you to disassemble the manifold and clean out any buildup in the main plenum body. 
• The manifold includes one -8 male fitting, two 1/8 NPT ports, one 2 bar MAP/temp sensor (can be upgraded to 3 bar), two mounting holes for intake plenum support bracket, and two mounting holes for throttle cable bracket. 
• Throttle body flange can be customized to the throttle body of your choice. Non-custom options include 84mm OMD throttle body and 90mm VDO throttle body
• Color: Black Wrinkle (can be done in red or blue wrinkle as well), we do not polish, coat, or paint the original Cosmo intake runners only the billet plenum.

*Requires you to send in stock 20b upper intake manifold for modification*
