Over the years with the RV-8A I've had to repair the air box and replace the filter. As you can see from the first photo, the bottom of the filter deforms (curves in). This tends to shorten the filter such that it drops out of the top and impairs the seal with the top plate. I also had to add fiberglass to the bottom of the air box as the relative motion between the bottom of the air filter the air box eroded away the fiberglass bottom. The fix was to add a .032" aluminum plate to the bottom of the air box. The plate eliminates the bottom erosion and the added brackets hold the filter shape. A side benefit is that alternate air door now sandwiches the bottom fiberglass between two piece of metal making a sturdier install. I also took the step to add proseal between the aluminum plate and the air box bottom.
