Fit as described
Used to install an inner fender liner. Seem a little more fragile than OEM, but suitable for the intended use and much less expensive.

Noticeable Improvement in Engine Smoothness
Size: 150 ml, Pack of 1
I decided to try LIQUI MOLY Valve Clean to help keep the intake valves clean and maintain engine performance, and I’m really impressed with the results. After adding it to the fuel tank and running through a full tank of gas, the engine felt noticeably smoother and more responsive.
It’s very easy to use—just pour it into the fuel tank as directed. I also like that it’s from LIQUI MOLY, a brand known for high-quality automotive additives.
While it’s not a miracle fix for serious mechanical issues, it’s a great preventative maintenance product to help reduce deposits and keep the engine running efficiently. I plan to use it periodically as part of my regular maintenance routine.
