The Fel-Pro valve stem oil seal set for Nissan Frontier supplies application-specific seals to control oil at the valve stems during engine service. Designs vary by application—deflector, O-ring, or positive styles—and kits are reviewed and validated by Fel-Pro engineers. The set includes an installation aid to protect the seal lip and is matched to the vehicle’s service requirements.
