NGK LASER IRIDIUM SPARK PLUG
This is 1 step colder spark plug for your turbocharged or supercharged Jeep Wrangler 3.6. Great replacement to help remove additional heat from the combustion chamber. Recommended if your stock plugs have over 30,000 miles. Best choice for complete combustion and avoid cylinder misfires. This is the plug we run in our 500+ Rear Wheel Horsepower Wrangler.
