IPP Viton Valve Stem Seals(Full set of 24) - Nissan 300zx

These Viton valve seals are made from higher quality material than the OEM valve stem seals even though they cost less. Viton has superior properties to the rubber used in the OEM seals and is good to over 450 degrees F where as the rubber in the OEM seals is only good to just over 300 degrees F.

We recommend replacing valve stem seals any time heads are being reworked, rebuilt, or upgraded. We use these high quality Viton seals in all our VG30DETT packages.
