Designed to seal up the lower valve cover bolts, these grommets help prevent oil seepage and ensure a tight fit that holds up under heat and pressure. Over time, the factory rubber can dry out and crack, leading to pesky leaks. Swapping them out with fresh, quality replacements from Merchant Automotive keeps your engine leak free.
When you're chasing down a leak or doing a full top-end refresh, grab a single grommet or a full set and get the job done right the first time.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.

The best no show socks
The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.
