Takai Performance Spark Plug, fits most sport bike applications

RType SERIES I
TAKAI Iridium RTYPE ultra high performance spark plugs are the perfect choice for engines that require smooth engine response and the MOST power output from idle to redline.

Designed for all types of powersport engines and designed to be the best, the Iridium RTYPE lineup is essential for unleashing the power in your engines combustion chamber!

The fact is, engines NEED a hotter spark for a more complete, higher horsepower combustion event. A small spark can only release an equivalent amount of energy in another process; such as starting a flame kernel in the combustion chamber. This is why it is also critical to increase available spark output to increase engine output. By increasing spark output more energy per combustion event can successfully be released.

Iridium RTYPE spark plugs allow the full potential of an engine to be realized by reducing energy losses from the ignition coil through its focal technology. Much like a laser focuses light the R-TYPE spark plugs focus electrical energy for the hottest, most effective spark available! Put simply there is simply no spark plug able to match the focal output of the Iridium R-TYPE spark plugs.

The Iridium RTYPE spark plugs come with professional level features such as, Focal technology output, RTYPE copper core, RTYPE copper grounding system, and our exclusive power insulator designed to reduce flame quenching, providing you with unbeatable performance vs any competing spark plug.

Benefits of the TAKAI RTYPE SERIES I spark plugs:

- higher fuel economy vs competitor designs
- higher power output vs competitor designs
- higher engine efficiency
- smoother acceleration
