ECS Tuning Engine Bay Block Off Plugs - Set - Audi B9

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.
