Description
ECS Tuning Engine Bay Block Off Plugs - Set - Audi B9From the factory, the B9 Audi comes with plastic 3 pronged caps to plug the holes in both wheel wells. Unfortunately when driving in wet, dirty, or snowy conditions, these unsealed gaps allow all of that mess to sling off of your tires, directly onto the cap and into the engine bay. This results in not only a messy look but allows corrosive salt to enter the engine compartment. Check out our before and after photos for a side by side comparison, or

Works well and doesn’t break the bank
Style: 36 Sqft 80 mil
Awesome value for low budget wound deadening. Used this under the floor mat on my international 4300 and there is a noticeable difference in sound inside the cab.
