NGK Spark Plug CR7E 4578

Product Information

NGK has been developing spark plug technology since the 1930s and manufacture plugs for every type of automotive engine, as well as for motorcycles, marine, horticultural, plant and many other applications. Any change in production is expensive for a manufacturer and therefore new spark plug types are only produced where necessary.

From exhaust, cylinder kit, drive belt, clutch, crankshaft, CDI, carburettor, air filter, battery to body parts - we have it. The vast experience and technology that NGK has ensures that there is no doubt that NGK are the world No. A hot spark plug is designed to maintain a sufficiently high temperature at the insulator nose to burn off carbon and oil deposits. OEM quality •Triple-gasket sealing process •Consistent performance •Plug of choice in millions of vehicles This plug is a Long reach resistor type spark plug, with 10mm x 1mm thread, fits with plug caps that use a threaded end on the spark plug. NGK always works very closely with the engine manufacturer to ensure a perfect match between plug and machine.Some engines require the use of two spark plugs per cylinder and again due to space restrictions these might be of different sizes. To combat the ‘cold fouling’ effect that can occur in some engines using unleaded fuels specially arranged ground electrodes are sometimes used.

If the tightening torque is too low, it is possible that the spark plug will lose compression and overheating.By raising the pre-ignition rating with the high conduction copper and leaving the insulator nose long; NGK produces the Wide Range Plug. Increased heat resistance does not affect fouling resistance; which is primarily determined by the insulator nose length.
