Review on Dewhel Billet Engine Oil Fuel Filler Tank Cap Cover - Purple, for Honda Acura Civic TL by Howie Broyles

This cap fits well, looks good and is well made, but it's not perfect. The rubber seal is not very tight so it falls off easily. This wasn't a big issue for me though, I used RTV silicone to glue the gasket to the lid to keep it from falling off so this issue is easy to fix. Civic and loose sealing issues seem to have been resolved as the second cap I bought a few years later had an o-ring pressed into the machined groove rather than a rubber washer that was loose on the cap and the new design seems very solid so I don't expect problems with a loose gasket like the old design.
