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 1 step colder than the stock plug. This is good for highly modified engines and can help prevent detonation or pre-ignition caused when the spark plug tip gets hot- causing a 'hotspot'. Colder plugs transmit heat away from the plug tip faster to avoid this. For more highly tuned engines we also stock NGK 8 rated plugs, as well as the stock 6 heat rated plugs, in both Iridium or Platinum.

We have a large and rapidly expanding range of items for the Silvia- consumeables, performance upgrades, tuning items. Please check out the other items in our shop for brakes, water pumps, spark plugs, filters, fuel pumps, and lots of other essential parts. Our eBay store also contains a wide range of suspension and steering parts- Kei Wheels, wheel bearings, strut bars, anti roll bars, camber arms, & performance uprated bushes.
