Ferrea Viton Valve Stem Seals for popular Honda engines are designed to provide exceptional lubrication while keeping oil out of the combustion chamber.
Only Viton is able to provide precise oil control and maximum durability, even at high rpm. Unlike OEM Honda valve stem seals that use different materials for both intake and exhaust seals, all Ferrea seals exceed OEM specifications and are manufactured from high-quality Viton.
Each seal also features stiffer retaining springs for a precise fit. The results are a seal that’s resistant to extreme heat, oil additives, and abrasion.
Fits D-Series, B/H/F-series VTEC, K-Series and F20C/F22C.
Sold individually, buy "8" intake and "8" exhaust for a full set on 4 cylinder engines.
