    Warranty Information

    Find out everything you need to know about the product warranty

    Karlyn Industries/STI distributes high qu ality COP components. We utilize independent engineers to monitor our coils and test warranties. Most coils that are returned DO NOT have a proble m. Rough running engines that set misfire codes can have multiple causes. It is t he responsibility of the dealer/installer of our products to verify that the following items of inspec tion have been performed, in order to compl y with warranty replacement. General misfire codes are most likely due to an intake vacuum l eak or fuel delivery problem. Misfire codes identifying a parti cular cylinder are usually due to a fouled spark plug; dirty or dead fuel injector or loss of compression in the cylinder (burned or bent valve, w eak or broken valve spring or leaky head gasket.)If the crankshaft position sensor fails, the loss of the basic timing signal will prevent the syst em from generating a spark and the engine will not start or run. A failed driver circuit within the power train control module (PCM) can kill an ind ividual coil and prevent that cylinder from firing. Replacing the coil without addr essing the cause will only result in another damaged coil. Misfire codes can also be triggered from a damaged wire harness due to poor grounds. Inspect the wire harness carefully. You may have to cut back the insulation to verify that there is no corrosion or melt ing of the wire harness due to poor grounds. A faulty harness can cause the coil to fail. If you simply install a new COP it may seem like you have corrected the problem but, merely replacing the coil without r epairing the grounding problem may result in future coil failures. In summary, it is important to re member that ignition misfire can also be caused by other factors such as worn or fouled spark plugs, loose or damaged coil connectors or terminals, dirty fuel injectors, low fu el pressure, intake vacuum lea ks, loss of compression in a cy linder, even a tank full of "bad" gas contaminated with water. These other possibiliti es should all be ruled out before a COP unit is replaced. (N ote: A fouled spark plug can damage the COP. We recommend that you always replace the spark plugs when you replace the COP units and that all the ig nition coils be replaced at the same time. As a form of preventiv e maintenance we suggest this be done every 60,000 miles) We will do our job to monitor and test the integrity of our coils. We hope that this information will help you to enhance the re liability and credibility of your repair while complementing our product. The main goal here is a real solution to your ignition problem which will result in happy customers. Temporary solutions will only result in the return of non-def ective parts and unhappy customers who will continue to have the s ame problem.
