No, it won't add 20 horsepower, but it can definitely help keep debris and the elements out of your fuel substantially better than the stock, flimsy cap can. 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 the recognizable diesel green color.
