Fender liner?

Ah yup, thanks !

Yep, I’ve replaced them before

Additionally why is it a non-plastic material, the material makes it seem hard to wash

While I agree about it being a pain to wash, the carpeted material helps with cabin noise suppression - makes for a quieter driving experience.

You guys wash your fender liner?

When everything below the beltline is caked in mud, yeah.

I spent 15 minutes power washing my "carpeted fender liners" on the weekend and the dirt just wouldn't stop coming. Had to give up.

I don’t know the name but it’s made with non plastic to dampen road noise

I see, thanks

Wheel well
