Fewer Volts Means More Amps
DENSO Iridium spark plugs require on average 5,000 fewer volts to fire than conventional spark plugs.
Less power is required to fire DENSO Iridium Power Plugs, and coupled with our patented U-Groove technology, the use of Iridium alloy, the tapered cut, and the ultra fine 0.4mm diameter electrode translates to increased horsepower throughout the dyno range.
"DENSO Iridium Power is the only true performance spark plug on the aftermarket today. We've tested hundreds of spark plugs at our facility and no other plug has ever made an increase in horsepower and performance on our dynos, like the DENSO Iridium plug."

"It takes 5,000 volts less to fire a DENSO Iridium Power spark plug versus a conventional platinum spark plug.
