The Parts You Need
Here at 4WheelParts.com, we offer high-quality factory style replacement 2.5L 4-cylinder engine parts for your 1987-95 YJ Wrangler. Give our 4-cylinder engine diagram a look and if you can't find what you need, our expert customer service representative can help you figure out exactly what needs to be replaced. We offer durable, reliable parts so you can get your Jeep back in tip top shape. Make sure your off-roading experience is the best it can be and order your Jeep engine replacement parts from our huge inventory.

The Power You Want
From driving across sand dunes to maneuvering rivers and climbing hills, your Jeep's engine needs to be functioning at high capacity. If you notice that your Jeep Wrangler's engine is beginning to show signs of age or damage, replace parts to make sure your rig can continue to brave the trails with you.

The Price You Deserve

Your Jeep is an investment, but that doesn't mean you should have to spend a fortune to maintain its condition. That's why 4 Wheel Parts proudly offers a 100% Price Check Guarantee. If you find the part your purchased at a lower price within 90 days, we promise to match that lower price and give you a refund for the difference. To add to that, we also provide shipping free of charge on all qualifying orders of $99 or more. Order your Jeep Wrangler engine replacement parts from 4 Wheel Parts and make the most of your money and your Jeep.

Your Jeep is built to last, but its engine components likely won’t live forever. Whether you limit your driving to the blacktop or constantly look for rough-cut trails to conquer, your Jeep’s engine requires occasional maintenance, repairs and upgrades. Here at 4WP, we are with you every step of the way.

Tough Valve Covers
When your Jeep was new, you didn’t have to give much thought to your valve cover. Unfortunately, over time, even the best Jeep YJ Wrangler valve covers require replacement. When you are ready to replace yours, rely on our inventory and expertise. Our inventory of valve covers features top-quality components that are designed to restore your engine’s performance. When ordering your new valve cover, remember that grommets may be sold separately. Check your order carefully to make sure you are getting everything you need to finish the job.

Durable Gaskets
When replacing your rig’s valve cover, you need to be sure you use a high-quality Jeep valve cover gasket. If you miss this critical piece, you may ruin your new valve cover entirely. For years, Crown Automotive has led the pack in creating durable, strong and flexible valve cover gaskets that form tight seals and prevent oil leaks. Whether you have a 1995 Jeep Wrangler engine 2.0 or a 2.5 Wrangler engine, you get a successful valve cover replacement when you finish up the project with one of these gaskets. Use our select vehicle tool to find the right gasket for your new or vintage Jeep. If you need additional help, rely on the skill of our knowledgeable parts experts.
