Turner E9x Cowl Delete Harness Mounting Bracket mounts to factory bolt holes; it is an easy no-drill install that creates a solid location to tie back your engine harness. However, removing the cowl introduces the possibility of dirt and debris entering your cabin. To solve this issue we suggest pairing it with Burger's Cabin/Cowl Delete Filters. These are small, dry, and maintenance-free filters that both add a finished look to your engine bay and prevent debris from entering the cabin.
