The Story
No, it won't add 20 horsepower or make your engine last any longer, but it sure looks a heck of a lot better than that ugly stock plastic fuel cap!Â
The Sinister Diesel Billet Fuel Cap is a stylish and durable option to keep dirt and moisture from entering your fuel tank. The factory uses a small, flimsy plastic plug and the Sinister Diesel Fuel Plug is CNC Machined from solid billet aluminum and utilized a tight O-ring seal. It's laser etched with the Sinister Diesel logo and anodized in Sinister Blue, green, or gray.
