Uprated NGK Iridium Spark Plugs
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 7 which is equivalent to the stock plug. This is good for mildly modified engines and you get the benefit of the NGK Iridium technology- better starting, more efficient combustion and increased efficiency. For more highly tuned engines we also stock NGK 8 rated plugs, as well as ultra cold 9 heat rated plugs.
If you are in any doubt as to what plugs would be suitable for your car, please contact us.
