Autolite Racing Spark Plugs are the choice of many professional race car drivers, as they offer a range of features that deliver maximum performance and improved durability. These spark plugs contain an Yttrium-Enhanced Alloy, which enables up to an 8% reduction in side wire temperature, resulting in improved durability and less pre-ignition.

The Autolite racing plugs are available in colder heat ranges than most plug manufacturers, allowing them to support modified engines.

Additionally, the plugs are nickel-plated, providing a long-lasting, corrosion-resistant finish.

One of the key advantages of Autolite spark plugs is their construction. The automotive replacement spark plugs are designed with anti-corrosive nickel-plating, which prevents rusting and maintains the plug's durability and efficiency. This feature ensures that the plugs continue to deliver optimal performance throughout their lifespan.

The company has been in operation for over 100 years, and its spark plugs are trusted by both the automotive aftermarket and original equipment manufacturers.
