    Key Features. Ditch your old, worn out Oil Cap with this direct OE replacement. Nothing is worse than finding oil has leaked out onto the engine block, plus it can hit the exhaust manifold and smolder, making a horrible smell and kicking out smoke. This component will seal things up tight again, plus it looks great. A 5 year limited warranty is provided by the manufacturer.

    Construction. Omix-ADA uses automotive grade ABS plastic to make this Oil Cap. That means it can withstand normal engine operating temperatures and even beyond, plus freezing cold, and whatever else nature throws at it, all without cracking or changing shape. A rubber gasket is included as well, sealing the opening tightly and maintaining its pliability for years.

    Installation. Really anyone can install this component, because it literally does not require any tools and no mechanical experience. Simply unscrew the old Oil Cap, then screw this one into place as tightly as you can. This should take no more than five minutes of your time, so you can get back to having fun.

    Application. This Oil Cap has been created for 1997-2006 4.0L Jeep Wrangler TJ Models.

      Cheap way to fill the hole

      If you have that freak rock bounce from under the hood to your oil fill cap like I did this is an inexpensive fix for a part that needs be nothing else. Fits just like factory.
