Silver Horse Racing has come out with a new Billet fuel door for the 2011 Mustang GT 5.0 showing us a little mod can go a long way to improving the look of your car. I have never really been a fan of the fuel door mod but this new billet fuel door from SHR with the ‘5.0’ engraved in it looks pretty sweet. The fuel door also saves weight with a reduction of approximately 1 lb over the OEM door. Installation can be accomplished in about twenty minutes with basic hand tools and the door is held shut with rare-earth magnets. The ‘5.0’ billet fuel door retails for $119.00 through SilverHorseRacing.
