IE DIY Intake Manifold Kit For 4 Cylinder Engines




* Required Fields


This Integrated Engineering DIY intake manifold kit for 4 cylinder engines with 88mm port spacing has been engineered to provide market leading performance and features.

The manifold plenum features a unique modular design with a symmetrical plenum that allows placement of the throttle body on either side of the engine.  The plenum has been very carefully optimized to distribute airflow evenly to all 4 cylinders regardless of the loading conditions. The plenum has been generously sized to ensure maximum cylinder charge at high RPM.  Each manifold plenum is cast, machined, inspected and packed all in the USA. The plenums are cast from a special self aging, self hardening alloy with especially strict requirements for chemical composition. Top of the line Japanese machining centers machine all major surfaces of the parts in one setup, ensuring perfect fit, finish, and maximum value.

The Integrated Engineering billet plenum flange is designed as a perfect fit solution for both the plenum and welding custom runners using RMR oval tube.  CNC'd in house from one solid piece of aircraft grade aluminum, the plenum flange is tuned for medium to high RPM power.  Carefully designed and flow tested velocity stacks deliver more air to the cylinder than any other manifold design on the market.
