Are there fake NGK plugs?
Yes, in fact it does. NGK SPARK PLUG’s Technical Service team recently became aware of cases where customers bought CR9EIX NGK spark plugs on the internet, which proved to be fake products.
What do the NGK numbers mean?
The heat rating is a measure of the amount of heat dissipation. The heat range of a spark plug is the range in which the plug works well thermally. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.
Which is better a resistor or non resistor spark plug?
Since resistor type plugs actually “resist” some of the spark energy, non-resistor type plugs actually deliver a more powerful spark. It is for this reason that most racing plugs are non-resistor types. However, in most automotive applications, a resistor plug is required for proper vehicle operation.
How do I know if I need a resistor spark plug?
It is for this reason that most racing plugs are non-resistor types. However, in most automotive applications, a resistor plug is required for proper vehicle operation. Use of non-resistor plugs in vehicles that call for a resistor type can result in rough idling, high-rpm misfire, and abnormal combustion.
Why do most vehicles require resistor spark plugs?
Most spark plugs contain a resistor to suppress radio interference. The gap on a spark plug is also important and must be set before the spark plug is installed in the engine. If the gap is too wide, there may not be enough voltage to jump the gap, causing a misfire.
Is NGK Made in USA?
Starting with a single product in 1936, NGK’s extraordinary growth can be attributed to a philosophy of manufacturing the product where it is going to be used. In fact, a substantial number of NGK Spark Plugs and oxygen sensors sold in the United States are made right here in America.
Are NGK Spark Plugs made in Thailand?
LTD. Establishes a New Production Plant in Thailand to Strengthen the Production Capacity of Various Automotive Sensors.
