Set 4 Uprated Spark Plugs
NGK V-Power Racing Plugs
Ultra Cold- Heat Range 9
These plugs are ultra cold heat rating 9 which is 3 steps 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. We also stock NGK 7 & 8 rated racing plugs.
Please Note- These Racing Plugs are NON Resistor
