Automotive Spark Plug

As a world leader in spark plug manufacturing, Champion knows what it takes to keep your engine running at its best. When it’s time to replace your plugs, Champion your engine with spark plugs that help improve performance and reduce wear and tear.

Product Description

Champion Double Platinum Power spark plugs deliver more powerful performance. Featuring exclusive Heat-Active alloy, a platinum fine wire center electrode and a platinum pad ground electrode, spark plugs reach optimal temperatures quickly and maintain stable operating temperature under all engine loads, while providing maximum life and sharper spark focus.Step-by-Step Instructions for Installing New Spark PlugsStep 1 If necessary, set the gap on the new spark plug before installing it. In the past, it was necessary to use a gapping tool to make sure the gap in the spark plugs was the correct size. Today, Champion spark plugs come pre gapped, eliminating the need for this step most times. You should double check that the gap is correctly set; check your owners manual to find the distance for the spark plug gap and use a gap gauge or feeler gauge to check the distance. Step 2 Seat the new spark plug by hand; turning it clockwise at least two full turns. Once you have the spark plug snug, use the socket wrench with extension and spark plug socket to tighten it turning the plug clockwise. The plugs washer should be pressed against the mounting surface. Take care not to over tighten the plug; you can strip the thread on the head of the engine leading to costly repairs. You can also use a torque wrench to torque it to specification (OE service or repair manual). Step 3 Replace the spark plug wire boot or ignition coil and wiring connector. A plastic boot should click into place while a rubber boot may require a coat of dielectric grease on the inside of the boot for easy removal next time. Step 4 Repeat the removal and installation process for each spark plug. Thats all there is to it! If at any point you run into issues or have a question, consult your mechanic. These instructions are for informational purposes only and should not be used in lieu of seeking professional advice from a certified technician. We encourage you to consult with a certified technician if you have specific questions or concerns relating to any of the topics covered herein.
