As a powerful symbol of performance driven quality, this experience and commitment has led to design enhancements that optimize the performance of every spark plug Champion makes. Champion understands the importance of OE fit and form replacement parts and knows that these parts adhere to the industry’s toughest standards — and to yours. Step-by-Step Instructions for Installing a Champion Spark Plug Step 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 owner’s 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 plug’s 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. That’s all there is to it! If at any point you run into issues or have a question, consult your mechanic.
