Denso Spark Plug Iridium Twin Tip IK20TT Pack of 4pcs.

IRIDIUM TWIN TIP

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.

Built-in, Highly Reliable Resistor

All specification types include an embedded, highly reliable, monolithic resistor to eliminate electoromagnetic noise interference from all kinds of electronic devices.

360 Laser Welding

The iridium tip is mounted with an All-around Laser Welding
