NGK Spark Plug CR7E 4578

Product Information

Choosing the correct spark plug type will help a vehicle manufacturer meet legislated emission targets and assists the motorist in getting the best from their engine. The vast experience and technology that NGK has ensures that there is no doubt that NGK are the world No.

Oily deposits start to build up after this sort of mileage and can cause starting problems and a drop in performance. Compared to ordinary plugs with equal anti-fouling resistance; NGK Spark Plugs have a higher pre-ignition rating. Virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance.The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network.

Most parts are pattern or aftermarket although some will be genuine but are not always stated as being so.Our engineering departments work very closely with the engine and vehicle manufacturers to produce the ideal spark plug type for each application. These can force the spark to discharge across the insulator and thus burn away any built up carbon that could cause poor starting or misfires.

By producing a high intensity electrical discharge within the engines combustion chamber the spark plug provides the heat energy required to start the air/fuel mixture burning. By raising the pre-ignition rating with the high conduction copper and leaving the insulator nose long; NGK produces the Wide Range Plug.We use these cookies to understand how people use our site, and to make the experience better for everyone. The service life of a spark plug depends on the fuel type, engine condition, driving time and the engine temperature.

NGK always works very closely with the engine manufacturer to ensure a perfect match between plug and machine.NGK Spark Plugs are designed to transfer a high intensity electrical discharge across the spark plug gap producing enough heat energy to ignite the air and fuel mixture. It has corrugated ribs that prevent flashover and cold rolled threads to inhibit damage to the cylinder head. NGK engineers therefore make specific recommendations for each engine and the use to which it is put.
