Denso Iridium TT Spark plug continues to impress

Irish customers with its superb performance, increased lifespan and generous profit margins.

Distributed by Serfac Limited, the Iridium TT is the latest in a long line of world-first technology innovations from Denso. With the highest concentration of iridium of any product on the market, its unique technology combines the world’s smallest diameter electrode, at 0.4mm, with a needle-like 0.7mm platinum ground electrode.

This improves ignitability, vehicle acceleration/performance and fuel efficiency and vastly increases the lifespan of the plug to 120,000km – more than three times that of a standard nickel plug. This saves the motorist money and is more environmentally friendly.

“Denso is a brand whose products you can trust, says Liam O’Donohoe, commercial manager, Serfac. “The OE-level quality of Denso’s aftermarket product is not just talked about. It’s proven – and the 120,000km life span of the Iridium TT spark plug is the proof point of this quality.”

The Iridium TT plug sits at the top of the Denso range, therefore representin an ideal upselling opportunity and better profit margins for motor factors.
