    Give Your Engine a Tune Up. Your rig has been working hard for a long time. Even though you perform maintenance as needed, it’s important to give your rig a complete tune-up once in a while. That way old parts are replaced before they begin to reveal problems. This Omix-ADA Tune Up Kit is designed for that purpose. It offers everything you need to revitalize your engine’s performance.

    Revitalizes Efficiency with New Filters. Some of the replacement parts included in this kit are a new air filter and a new oil filter. These filters should be changed occasionally anyway and are simple to swap out. Installing these new filters ensures your engine receive cleaner air and oil, improving efficiency.

    Complete Spark Plug Replacement. Small and simple, your spark plugs ignite the air-fuel mixture in your engine. That’s an important job. Ensure this function is performed properly with the new spark plugs and spark plug wires included in this kit.

    Distributor and Rotor Upgrade. A new distributor rotor and cap are included in this kit as well. These essential parts are often overlooked but are important to replace every so often. They work to ignite the fuel/air mixture to power the engine too.

    Direct Fit Installation. All of these simple but vital parts are easy to replace using this tune-up kit. The kit is designed for direct fit installation. Since there are several replacements to make, expect to spend two hours on the job.

    Application. Your 1997 to 1998 4.0L Wrangler TJ will be running like new with this Omix-ADA Tune Up Kit revitalizing the engine.

            Great investment

            This was a great investment and easy install. My 98 Jeep Wrangler is running better than ever.

            So so.

            Everything was great except the distributor rotor and cap. After installation I fired up my Jeep and immediately heard a clunking noise. At first I thought I had messed up the firing order with the spark plug wires, but after opening the hood and looking around I noticed that the distributor rotor had popped off and put a hole in the cap. I cleaned up the old rotor and cap and everything fired up like normal.
