From 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 better yet, go check under the hood of your car - we'll wait.
ECS Tuning has you covered -- literally. Our in-house Product Development and Engineering team has come up with a perfect solution. These flexible injection molded polymer plugs seal out all of the nasty, leaving your engine bay and strut tower area squeaky clean. Featuring a matte black soft textured finished with a subtle embossed ECS logo, they look great and correct the factory mistake!
Our ECS Engine Bay Block Off Plugs were designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing.
*Note: Caps are side specific (marked DS for left side and PS for right side), see installation PDF below for more information on the install procedure.

We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.
Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.
Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".
A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.
"MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
