As with all preventive maintenance performed on a Jeep, tune-ups can prevent problems from occurring. The filters can clog with use and prevent flow, starving the engine of air and oil. Old spark plugs may cause engine misfires that can lead to less gas mileage and poor performance with your Jeep. Here at Morris 4x4 Center we have Tune Up Kits tailored to your specific Jeep with everything you need.
