Need a simple, sturdy replacement oil filler cap for your Toyota? This X AUTOHAUX cap is a solid choice. It’s made from high-quality black aluminum alloy, so it’s durable, looks clean, and helps prevent leaks. The thread size is M37x3, and it measures about 31mm tall by 57mm in diameter (that’s 1.22 x 2.24 inches). It comes with a rubber sealing ring already installed, which keeps oil vapors in and keeps water and dirt out of your engine bay. Installation is literally a twist-on – just screw it onto your oil filler neck in place of the old one. It’s a non-OEM part, but it’s designed to fit perfectly like the original. This isn’t a complicated upgrade, but it’s a smart one if your old cap is cracked, missing, or just looks tired. One cap comes in the package. Keep your engine bay looking tidy and protected with this simple, functional part.
