Product Details
The NGK 7901 Laser Iridium Spark Plug – IJR7A9, 1 Pack : Automotive is a spark plug that has a laser-welded iridium center electrode tip and a platinum disc welded to the backside of the ground electrode. These features ensure high durability and greater spark, as well as slow wear rate and lower emissions. The spark plug also has a tapered-cut ground electrode that improves ignitability and reduces quenching, a 98% pure copper core that increases heat dissipation and prevents overheating, a high-grade alumina silicate ceramic insulator for superior strength and heat transfer, and a trivalent metal plating for superior anti-corrosion and anti-seizing properties. The spark plug has a flat seat, a thread size of M12, a heat range of 7, a hex size of 18mm, a preset gap of 0.036 inch, a thread reach of 0.750 inch, a number of ground electrodes of 1, a center electrode core material of copper, a center electrode tip material of iridium, an approximate resistor value of 5000 ohm, an insulator height of 50mm, and a service number of IJR7A9. The spark plug weighs 1.23 ounces and measures 0.35 x 0.39 x 1.3 inches. It is sold in a pack of one and has a warranty of one year limited.
Product Features
The NGK 7901 Laser Iridium Spark Plug – IJR7A9, 1 Pack : Automotive has several features that make it stand out from other spark plugs. Some of these features are:
– Laser-welded iridium center electrode tip: This feature ensures high durability and greater spark, as iridium is six times more durable than platinum and has a very high melting point. It also provides consistent performance and stable idle.
– Platinum disc welded to backside of ground electrode: This feature provides long life and reduces the wear rate on both the center and ground electrodes. It also provides excellent ignitability and service life, especially in distributorless ignition systems.
– Tapered-cut ground electrode: This feature improves ignitability and reduces quenching, which is the loss of spark energy due to the interference of the ground electrode. It also enhances flame propagation and combustion efficiency.
– 98% pure copper core: This feature increases heat dissipation and prevents the spark plug from overheating, which can cause pre-ignition and detonation. It also offers superior conductivity and ultra wide heat ranges.
– High-grade alumina silicate ceramic insulator: This feature provides superior strength and heat transfer, which can prevent fouling, flashover, and leakage. It also has corrugated ribs that prevent flashover, which is the electric discharge between the electrodes and the metal shell.
– Trivalent metal plating: This feature delivers superior anti-corrosion and anti-seizing properties, which can ensure ease of installation and removal. It also protects the spark plug from the harsh environment of the combustion chamber.
Product Benefits
The NGK 7901 Laser Iridium Spark Plug – IJR7A9, 1 Pack : Automotive has many benefits that can improve the performance and efficiency of your engine. Some of these benefits are:
– Faster starts and quicker acceleration: The spark plug provides a strong and consistent spark that can ignite the air-fuel mixture faster and more completely, resulting in more power and torque.
– Better fuel economy and lower emissions: The spark plug provides a stable idle and optimal combustion, resulting in less fuel consumption and less harmful emissions.
– Longer service life and less maintenance: The spark plug has a slow wear rate and high durability, resulting in less frequent replacement and less hassle.
