Set 4 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 6 which is the stock plug heat rating. For more highly tuned engines we also stock NGK 7, 8, & 9 rated plugs, in both Iridium or Platinum.
If you are in any doubt as to what plugs would be suitable for your car, please contact us.
