DESCRIPTION
* Spark plugs may need to be gapped to fit your application. Check your manual for a proper gap size. *
NGK Laser Iridium Spark Plugs
Laser Iridium spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti fouling, improved fuel efficiency and lower emissions
Laser welded Iridium center electrode tip
Platinum disc welded to backside of ground electrode provides
long service life
“Trivalent Metal Plating” provides superior anti-corrosion and anti-seizing properties
Faster starts and quicker acceleration
Better fuel economy and lower emissions
Best OEM Iridium spark plug available
Original Equipment Manufacturer approved design
Are special plugs always necessary on a modified engine?
Modifications that will typically not require specialized plugs (in most cases the factory installed plug will be more than adequate) include adding a free-flowing air filter, headers, mufflers and rear-end gears. Basically, any modification that does not alter the overall compression ratio will not usually necessitate changing plug types or heat ranges. Such minor modifications will not significantly increase the amount of heat in the combustion chamber, hence, a plug change is probably not warranted.
However, when compression is raised, along with the added power comes added heat. Since spark plugs must remove heat and a modified engine makes more heat, the spark plug must remove more heat. A colder heat range spark plug must be selected and plug gaps should be adjusted smaller to ensure proper ignitability in this denser air/fuel mixture.
Typically, for every 75-100 hp you add, you should go one step colder on the spark plug's heat range. A hotter heat range is not usually recommended except when severe oil or fuel fouling is occurring.
