Supertech Inconel Exhaust Valve - +3.8mm Oversize - Set of 8 | 2002-2007 Mini Cooper (MCEVI-1012S-8)

Mini R53 Inconel Exhaust Valves by Supertech

Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines.

A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market

Please Note: Requires Single groove keepers KPR-6S/7. THESE VALVE CAN NOT BE USED WITH OEM RETAINERS
