Spark plug NGK DPR 8 EIX-9 Triumph Bonneville Scrambler Thruxton DPR8EIX-9
The new benchmark in terms of performance and reliability.
NGK Iridium IX spark plugs directly from the latest developments in competition. Designed to meet the demanding performance and eager customers , they conform to the specifications manufacturers.
Candles IX range can improve the performance of origin with respect to the acceleration , the ease of cold starting , the duration or life of the fuel economy.
They are particularly suitable for engines slightly prepared .
The use of an alloy of iridium ( noble metal ) reduces the diameter of the center electrode ( 0.6 mm instead of Iridium 2.5 mm nickel , platinum 0.8 mm ) , d obtain a very fine tip , and lower the need for ignition voltage . This feature ensures a more rapid ignition of the mixture and the ignition system protects .
The tapered shape of the ground electrode reduces the shadow zone ( zone unignited fuel ) , and ensures a quick ignition of the mixture .
The iridium alloy electrode shows superior resistance to high temperatures and erosion , its wear is slower , it may reach a service life 2.5 times greater than that of conventional spark plugs.
The anti- fouling system called staircase or " step 2 " also gives it exceptional performance for urban use and short trips .
