KPMI® Red valve stem seals are resistant to high temperatures, petroleum products and the corrosive gasses that are the by-products of combustion. These seals retain their ability to seal in situations where other materials could harden and allow oil to enter the combudtion chamber, causing detonation, carbon build up and a loss of power. The Red Ones are truly the racer’s choice. Part 61420 7mm 6mm 61422
