Due to vibration and inferior engineering, low-quality oil fill caps have been know to come loose and fall off while driving down the road. Don’t get caught in a bind! Performance Diesel’s BIG BOSS? Oil Fill Caps are carved from solid, high-grade billet aluminum for longevity and superior performance over typical stock oil fill caps.
Oil Fill Caps are NO LONGER a lock-tight design they are NOW a threaded design.
Keep your engine clean and running smooth.
