Skunk2 Honda/Acura (B/D/F/K Series) Viton Valve Stem Seal Kit

If you're rebuilding the top end of your Honda or Acura with a B, D, F, or K-series engine, these Viton valve stem seals from Skunk2 Racing are a solid choice. They're designed to do a critical job: keep oil from getting into your combustion chamber while still allowing the valve stem to be properly lubricated. This is essential for maintaining engine performance and longevity, especially in engines that see higher RPMs.

What sets these apart is the material: they're made from Viton, which is known for its resistance to extreme heat, oil additives, and abrasion. Skunk2 also includes stiffer retaining springs on each seal. This helps ensure a precise fit on the 5.5mm valve stems common in these Honda engines, giving you a more reliable seal than stock in many cases. They exceed OEM specifications, offering a durable solution for both intake and exhaust valves.

This kit includes 16 seals, enough for a complete engine. Making sure your valve stem seals are in good condition is a key part of any engine rebuild or repair to prevent oil burning and maintain compression.
