More Power, More Torque

More Power, More Torque

More Power, More Torque

  • February 11, 2022

Looking for more power and torque? Then you’ll find everything you need wrapped up in DENSO’s elite Iridium Racing spark plugs.

0.4mm Iridium-Rhodium alloy centre electrode requires less voltage to fire and increases firing performance. 100% pure Platinum 0.8mm ground electrode reduces risk of melting the plug during harsh racing conditions. As well as increased engine efficiency and fewer misfires, the Iridium Racing plugs best demonstrate their superior performance during acceleration.
