Autolite Revolution HT0 Spark Plugs (8)
**Single heat rage colder, designed specifically for Supercharger/Nitrous
Prevent pre-ignition and detonation of the fuel due to the higher cylinder temperatures found in supercharged or nitrous fed engines with Autolite HT series spark plugs!
Pre-ignition is typically caused by many factors, such as an overheated spark plug tip which acts like a glow plug to ignite the charge. This puts a tremendous load on the engine and adds considerable heat, and serious engine damage.
These AUTOLITE Revolution HT Series Spark Plugs are one heat range colder than the stock Mustang plug and are designed specifically to handle the high boost pressure nitrous, and air flow into the engine. These plugs are factory gaped at 0.045 inch.
