    Factory style replacement 2.5L 4 cylinder engine parts for your 1987-95 YJ Wrangler. Trying to track down components for your 1990 Jeep Wrangler 2.5 engine? Older parts can be hard to find, but you can trust 4 Wheel Parts to hook you up with the best gear and deals. Whether it's a Jeep 2.5 valve cover, a head gasket, and oil filter or anything else you need, we've got you covered.

    Both Small and Large Details Count
    A plastic valve cover is no big deal, right? At 4 Wheel Parts, we know better. When you're searching for even the smallest components for your Jeep Wrangler YJ 2.5 engine, we understand that quality counts in every little detail. Take our Crown Automotive Plastic Valve Cover, for instance. It's crafted for a direct fit as an OE replacement for the original part. Not only that, it comes from a company with more than 50 years of experience making Jeep components, including hard-to-find or discontinued gear. That's just one example, but every product in this category is sourced using our strict standards. Match that with great warranties, our expertise and commitment to stellar customer service and you understand why we're a leading supplier of parts for trucks, off-road vehicles and four-wheelers since 961.

    4 Wheel Parts is committed to providing you with top-quality YJ Wrangler engine parts—or any other components you need. Our dedication doesn't just stop at our stock of great gear and accessories, or making the shopping experience easy with features like our drop-down menus or the Jeep wrangler body parts diagram we've included on our site.
