Katech Gen III & IV LS Wet Sump Slotted Raw Cast Aluminum Valve Covers

Raw Cast Aluminum Covers with Oil Fill Access and Grooves for Personalized Inserts.

The Katech Gen III & IV LS Wet Sump Slotted Raw Cast Aluminum Valve Covers combine a raised profile with machined grooves for compatible logo inserts. Their uncoated finish offers a raw aluminum appearance, while the wet sump configuration provides oil fill access.
