Autolite AR3911-4PK High Performance Racing Spark Plug, Pack of 4

Autolite Racing Spark Plugs are a popular choice among many professional race car drivers. These spark plugs are designed with advanced features that enhance their performance and durability. At the heart of these plugs is an Yttrium-Enhanced Alloy, which enables up to an 8 percent reduction in side wire temperature. This improved temperature control helps to minimize the risk of pre-ignition, ensuring more consistent and reliable performance under the intense conditions experienced in professional racing.

In addition to the Yttrium-Enhanced Alloy, Autolite racing plugs are available in colder heat ranges than those offered by most other plug manufacturers. This allows them to better support the needs of modified engines, which often require a colder heat range to prevent pre-ignition and engine damage. The plugs also feature a cut background electrode, which enhances ignitibility and promotes faster flame kernel growth, leading to improved combustion efficiency.

Corrosion resistance is another key attribute of Autolite racing plugs, thanks to their nickel-plated finish. This durable coating helps to prevent rusting and ensures a long-lasting, high-quality appearance.

The Autolite brand has a rich history, having been in operation for over 100 years. During this time, the company has produced more than 11 billion spark plugs and glow plugs, cementing its reputation as a leading supplier of ignition products. Autolite's commitment to quality and innovation has made their spark plugs a trusted choice among both the automotive aftermarket and Original Equipment (OE) manufacturers.

Regardless of the make or model, Autolite has the right ignition product to meet or exceed OE quality and performance standards.

In summary, Autolite Racing Spark Plugs are a premium choice for professional race car drivers and enthusiasts alike. Their advanced design features, such as the Yttrium-Enhanced Alloy and colder heat ranges, combined with their corrosion-resistant nickel plating, make them a reliable and durable option for high-performance applications.
