Iridium TT® (TT Series)

Twin-Tip Technology

The Iridium TT® Twin-Tip technology delivers far less obstruction to the spark allowing an omni-directional explosion. This minimizes the quenching effect and results in a more effective, more complete combustion. Better combustion means more power and better fuel economy, as fuel is burned more efficiently with each piston firing. The large center and ground electrodes seen on a standard plug increases “quenching” of the explosion, meaning the spark explosion is restricted by the electrodes above and below the gap, allowing it to spread to either side, but not grow with full range.

Features:

• Titanium-enhanced alloy ground electrode
• 1.1mm platinum center electrode
• Minimum-quench electrode design
