Supertech Oversized Inconel Exhaust Valves For MINI W11 Cooper S
The Supertech Oversized Inconel Exhaust Valves are for MINI W11 R52 or R53 owners who want to increase airflow and volumetric efficiency that once paired with a larger set of inlet valves should result in more power. If you want to maximise airflow Lohen recommend porting the head at the same time as enlarging the valves.
These exhaust valves are 2.3mm larger than standard so it is important to note OEM retainers cannot be used when installing these Supertech valves.
Once these are installed, a remap will not be required to drive your MINI but it is recommended to get the most from the new valves.
- Head Diam: 25.50mm(+2.3)
- Stem Diam: 5.92mm
- Length: 118.37mm
- Material: Inconel
- Valve Type: Exhaust
- 8x Supertech Oversized Inconel Exhaust Valves
