High Flow, High Performance, Race Intake Manifold. CNR Intake Plenums are designed to maximize performance in highly tuned engines.

Made of cast aluminum.The fine cast-aluminum ones allow for large volumes of air to get evenly distributed to the cylinders. Super High Flow, Large Runner, Large Plenum.

IMPROVES HIGH END POWER Especially at high RPM.

Works well especially with performance cams and Big Bore Throttle Body. Pre-bored to accept Large Throttlle Bodies.

 To achieve the most from larger turbochargers at higher boost levels, a smooth flowing CNR Intake manifold is a must.

High quality cast iron turbo manifold for those who are piecing together their own turbo kits. Manifold and turbo chargr are the most important part of the turbo system, so do not skip on these components.

CNR turbo manifolds are made from cast iron to a strict casting standards. These manifolds are very durable and will withstand all the heat and vibration you can throw at them., Our manifolds casting exceeds OEM specifications and now come with 2 year warranty against cracking. All of our manifolds incorporate external 35 or 38mm wastegate, and either T25/T28 or T3/T4 standard turbine inlet. All internal surfaces are cast smooth for faster air flow and lower surface friction. These high quality units offer great flow characteristics and durability, Also very easy for mounting turbo charger & wastegate.
