YOUR GUIDE TO THE MOST POWERFUL PERFOMERS IN THE SPARK PLUG WORLD.

For a seriously smooth ride and boosted throttle response the world’s most powerful spark plug technology, Iridium, is what you need.   Leicester Auto Parts’ Iridium partner is DENSO – one of the world’s biggest names in auto parts innovation and manufacture, and the plug brand that powers the Panasonic Toyota F1 team and the Subaru World Rally Team!  

 How do Iridium spark plugs improve ignition and efficiency? Iridium technology plugs were invented to meet the trend of lean engine burn, to help comply with stricter emission control and fuel consumption targets worldwide.   Although spark plugs can't increase engine power, a more efficient spark will provide better combustion with associated performance and economy benefits.   Compared to ordinary plugs, DENSO Iridium spark plugs have a much finer, iridium alloy centre electrode.   This micro-thin tip reduces the voltage needed for a spark to occur, providing a much stronger spark, improving ignitability and delivering better engine performance.  

 What types of Iridium plug are available?   Leicester Auto Parts stocks DENSO Iridium Power, Iridium Tough and Iridium Racing spark plugs to suit your every need:

Select DENSO Iridium Power for an extra boost to your everyday motoring.   With the world’s smallest, 0.4mm radius iridium alloy centre electrode this plug offers superior ignition response, acceleration and torque compared to regular plugs, as well as improved fuel consumption and longer lifetime.
