The Sinister Diesel billet fuel plug for 2013–present Dodge/Ram Cummins 6.7L replaces the small factory plastic cap with a CNC-machined T6-6061 aluminum plug finished in Sinister Blue and laser-etched with the brand logo. It seals with a tight O-ring (Viton included) and has a magnet in the base to hold the plug during fueling, helping keep dirt and moisture out of the tank.
