Supertech Renault Clio RS F4R 16V 30x5.45x108.9mm T Inconel Exhaust Valve - Set of 8

These Supertech exhaust valves are made from Inconel, a high-nickel alloy known for its exceptional strength and resistance to extreme heat. This makes them a solid choice for performance builds where engine temperatures can get quite high, especially in the F4R 16V engine found in the Renault Clio RS.

Each valve measures 30mm in diameter with a 5.45mm stem and a 108.9mm overall length. The Inconel material is crucial for exhaust valves because it can withstand the intense heat and corrosive gases produced during combustion without deforming or failing. This set includes eight valves, enough to replace all the exhaust valves in your F4R engine. Proper valve seating and sealing are critical for engine performance and longevity, and these valves are built to handle demanding conditions.

When rebuilding or upgrading your F4R engine, using valves made from a material like Inconel ensures that this critical component can handle the stress. It's always a good idea to check your valve guides and seals when replacing valves to ensure optimal performance and prevent premature wear.
