NGK CR-8 EIX CR8EIX Spark Plug - white/silver

Product Information

Increased heat resistance does not affect fouling resistance; which is primarily determined by the insulator nose length. Owners who want the very best performance from their bikes will want the best spark plug and this wecan offer with Iridium IX.

These iridium plugs might cost a bit more in the short term but pay for themselves many times over, over their lifetime.

NGK IX spark plugs use of the precious metal Iridium allowing the manufacture of an even smaller diameter centre electrode without compromising durability. To combat the ‘cold fouling’ effect that can occur in some engines using unleaded fuels specially arranged ground electrodes are sometimes used.

Harder than other precious metals used in spark plugs and with an extremely high melting point; allow for an even smaller diameter centre electrode to be manufactured (0. Each and every spark plug manufactured by NGK is designed to meet the most rigorous standards, ensuring there ability to deliver reliability and consistent performance under all conditions.

A ´cold´ spark plug is designed to allow a faster transfer of heat to the cylinder head thus preventing overheating and premature failure. Modern engines manufacturers often require increased spark gaps to allow a longer spark duration; which again aids more efficient combustion. The heat range of NGK Spark Plugs is wider than ordinary plugs therefore they are suitable for both high speed and low speed driving. This fixed that issue and although I can't tell much difference because I'm on a 125, I'd definitely recommend this.
