What happens to spark plugs in Subaru WRX?

What happens to spark plugs in Subaru WRX?

An over-torqued spark plug can suffer from severe stress to the Metal Shell which can distort the spark plug’s inner gas seals or even cause a hairline fracture to the spark plug’s insulator. In either case, heat transfer can be slowed. – If you have a tuner, consult with him before buying plugs.

What kind of platinum is used for spark plugs?

Platinum or iridium can be used as a thin pad which is laser welded on the ground electrode (the “J” strap), this serves to increase the life of the plug. Heat Range: Heat range deals ONLY with the temperature of the insulator of the plug (the white part).

How often should I change my spark plugs?

That depends on how often you are interested in changing the spark plugs. Conventional spark plugs generally last one year. Platinum or iridium can last, depending on manufacturer specifications, up to seven years. What’s some good background spark plug information?

What happens when a spark plug is used?

Radio Frequency Interference (RFI): When the spark plug creates a spark, a high frequency burst of energy is created. If this energy was to travel through the ignition wires, it could cause interference with other sensitive electronic devices, such as the radio or electronic control units.

What causes an arc on a spark plug?

The high voltages of modern ignition systems could cause an arc, known as flash-over, from the terminal of the plug to the metal shell of the plug. The corrugations essentially increase the surface distance from the tip to the ground of the plug.

How to tell if your Subaru Forester has no spark?

By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms (no start, high idle, misfire etc.) Along with any prevalent Diagnostic Trouble Codes, aka DTCs, other forum members will be able to help you get to a solution more quickly and easily! 2005 Subaru Forester, crank, no start, no spark

What to do when your engine has no spark?

Insert a spark plug tester into the plug boot and ground it on a piece of metal on the engine. Finally, Have someone crank the engine and watch for spark. Remove one of the coils from the spark plug. Use an extra spark plug. A spark plug tester. Or even a screwdriver in the end of the coil.

What happens when a spark plug is over torqued?

This will tend to elevate combustion chamber temperatures to unsafe levels, and pre-ignition and detonation will usually follow. An over-torqued spark plug can suffer from severe stress to the Metal Shell which can distort the spark plug’s inner gas seals or even cause a hairline fracture to the spark plug’s insulator.
