Set 6 Uprated NGK Iridium Spark Plugs
1 stage Colder than Stock- for Modified Engines
NGK Iridium technology spark plugs utilise the latest in technology and also laser welding construction techniques. This enables a centre electrode size of just 0.6mm! The smaller the size of the electrode the less voltage is needed to jump the gap- this means more spark energy to ignite the mixture.
These plugs are heat rating 6 which is 1 step colder than the stock plug. This is good for modified engines.
