The original R53 intake manifold, is another restriction in the intake system.

Even vehicles with high performance modifications like big valve heads and upgraded camshafts are restricted by the oem design, as the restriction lays between the intake and the cylinder head. 

​Engines need air in order to combust fuel. The more air, more the fuel that can be combusted and ultimate more power output.

 

Our main goal was to maintain, as much as possible, the same pressure in all four runners exit, while maintaining the same outer dimensions as the original unit. To achieve this CFD (Computational Fluid Dynamics) Simulation was used. And we redesigned of the inner surfaces of the intake manifold.

 

Main objectives during the development process:​

• Plug and play fitment. 

​ As with all our products, this intake manifold is a plug and play unit.To achieve the above, we used 3D Scanning, CAD and 3D printing.

• Maximum Gains.

 Multiple CFD integrations were used until we were happy with the pressure distribution and many prototype models were tested in real world scenarios and dyno runs.

​

The R53 intake manifold is a direct bolt-on engine upgrade that requires no modifications. It comes with all the required hardware  necessary to complete the installation.

 

Gains in the whole rpm range.

Huge gains from the 2500 to 5000 rpm with +40Nm and 15Whp at 3000 RPM and +10Nm and 12 Whp at the redline.

Disclaimer: Results may vary depending engine spec. 

 

Additionally, we saw lower intake temperatures and faster recovery time.

ECU calibration was necessary as after the installation of the TPE Precision manifold as the AFR was on the lean side.
