Are Torque Master spark plugs designed for everyday, non-modified cars or just high-performance vehicles?
Torque Master spark plugs were specifically designed to run better and to produce more power and more miles per gallon. Extreme longevity was a gift — created by design. We knew they would last longer, but they are beating our projection by a very large percentage — without degrading the performance. In fact, these plugs keep improving with age, 100,000 miles is a breeze. A Ford V8 with over 243,000 miles still passed California smog!
