Iridium TT Spark Plugs
The full European range of Denso Iridium TT Spark Plugs. The latest Spark Plug innovation from world leaders Nippon Denso.
This range of 19 Spark Plugs covers approximately 90% of the current UK car market. Suitable as a significant upgrade to many Original Equipment copper, Iridium and platinum spark plug types and offering superior ignitability. Benefits may include improved throttle response, lower emissions, improved economy and extended plug service life.
These new (as of December 2015) Iridium Twin Tip (TT) spark plugs are the very latest design and offer the ultimate in value for money, making many NGK Iridium IX spark plugs obsolete. Prices are per spark plug, please add the number of plugs you require to your shopping cart.
Electrodes are constructed from 0.4mm Iridium alloy (centre electrode tip) and 0.7mm Platinum alloy (ground electrode tip), this combination of service life and performance cannot be beaten with any other aftermarket spark plug design.
As with all spark plugs, but especially where Iridium tipped electrodes are used, re gapping should not be necessary for most applications, take extreme care if you feel it is necessary to adjust the gap for your engine before fitting.
