Set of 6 Spark Plugs
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.
For complete combustion, the Iridium TT’s two tips allow the spark plug to create the largest spark concentration and explosion, which translates into more power and superior fuel economy than any other plug.
With this unique design, there are literally two “tips”: a 0.4-millimeter Iridium center electrode, and a 0.7-millimeter Platinum ground electrode. DENSO’s patented Twin-Tip technology was first used on original equipment spark plugs for luxury and performance cars. Now, that technology is available to everyone.
The Iridium TT’s revolutionary 0.4 millimeter center electrode means significantly improved combustion and fewer misfires – optimizing power output like never before.
Invented by DENSO, the Iridium TT Twin-Tip Technology enables larger spark concentration and explosion, delivering more complete combustion, which translates to more superior fuel economy.
The unparalleled Iridium TT spark plug is tested to last well beyond 100,000 miles, with minimal loss to performance, contributing to more overall lifetime savings than any plugs available today.
