What does metal shell stretch do to spark plugs?
Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental. 2.
Why do spark plugs have copper cores?
A copper core is used to increase heat dissipation and durability by lowering the electrode temperatures . Nearly all NGK spark plugs, including precious metal iridium and platinum plugs, have a copper core to increase the electrode durability.
What is NGK spark plug?
NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize.
What tool to use to measure spark plug gap?
Care must be taken to avoid bending or breaking off the fine-wire electrodes. NGK recommends a round wire-style or pin gauge gap tool to measure the gap.
Why is torque important?
Torque is crucial in the ability of the plug to dissipate heat and perform properly. Always follow the manufacturer recommended torque specification. An under-torqued spark plug can lead to excessive vibration and improper heat dissipation, causing spark plug and/or engine damage.
Can NGK spark plugs be lubricated?
NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Thread breakage can sometimes involve removing the cylinder head for repair.
Why do spark plugs seize?
When carmakers switched to platinum-tipped spark plugs that lasted up to 100,000 miles, spark plugs started to seize in the cylinder heads . The problem got even worse as carmakers switched to aluminum cylinder heads. The dissimilar metals went through a galvanic reaction where metal transferred and welded the spark plugs to the head . When the DIYer or professional tech went to remove the spark plugs, they would often rip the threads right out of the cylinder head.
What happens if you don't use anti seize on spark plugs?
If you don’t, you’ll over-torque the plug and damage it. If the spark plug has a black oxide finish, it has NOT been coated at the factory and you should apply a very small amount of anti-seize to the threads.
What is NGK spark plug?
NGK spark plugs are manufactured with a trivalent plating. The spark plugs display a silver or chrome finish on the threads. The trivalent plating reduces corrosion resistance from moisture and chemicals. The trivalent coating also acts as a release agent during spark plug removal.
What plating prevents threads from seizing?
Most spark plugs have either a zinc or nickel plating that prevents the threads from seizing in the cylinder head. That’s different from decades ago when spark plugs didn’t have any coating and could seize in the cylinder head, making removal tough.
How long did spark plugs last in an engine?
In the old days when engines and cylinder heads were made from cast iron and copper spark plugs only lasted 12,000 miles, there was no need for anti-seize. The spark plugs never stayed in the engine long enough to seize in the cylinder head. Plus, they were similar materials—steel and cast iron.
Why are Champion spark plugs zinc plated?
Champion spark plugs are zinc plated to reduce the chance of seizure in aluminum cylinder heads. Champion then applies Tin Tac” and ULTRASEAL’M coatings over the plating to further reduce corrosion and seizure. Anti-seize should NOT be applied to new Champion spark plugs.
What does anti seize do to a torque wrench?
Anti-seize is a lubricant and affects torque values by up to 20 percent. If you use anti-seize against NGK recommendations, you MUST decrease the set torque on your torque wrench by that amount or risk breaking the spark plug, distorting the shell, or damaging cylinder head spark plug threads.
