NGK Spark Plug CR7E 4578

Product Information

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. NGK engineers therefore make specific recommendations for each engine and the use to which it is put. 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. Triple-Gasket Sealing Process Virtually eliminates the possibility of combustion gas leakage through the shell.

Put simply, NGK genuine spark plugs are the workhorse at the heart of smooth-running engines around the world. 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. It has corrugated ribs that prevent flashover and cold rolled threads to inhibit damage to the cylinder head. Changes in fuelling systems and the fuel itself have meant some special features being adopted at the ‘firing end’ of the spark plug.

Their vast experience and the technology that NGK uses ensures that there is no doubt that NGK are the world's No. They may be used by those companies to build a profile of your interests and show you relevant adverts on other sites. Increased heat resistance does not affect fouling resistance; which is primarily determined by the insulator nose length.

Copper’s superior heat conductivity dissipates the heat of combustion away from the firing end, preventing hot spots that can lead to pre-ignition. The service life of a spark plug depends on the fuel type, engine condition, driving time and the engine temperature. The NGK Standard Spark Plug is constructed from durable material that is corrosion and abrasion resistant. 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.
