Description

The Bosch FR7NI33 is a 4-cycle spark plug featuring Double Iridium electrodes for enhanced performance and longevity. Its design includes an iridium center electrode firing pin and an iridium ground electrode inlay, offering improved ignitability and durability. The plug has a pre-set gap of 0.027 inches and a 26.5mm reach with a 16mm hex size.

Constructed with a ceramic insulator, this spark plug utilizes a copper core for a broader heat range to prevent pre-ignition and fouling. The nickel-plated rolled threads resist corrosion and do not require anti-seize for installation. Bosch offers a 7-year performance guarantee on their OE Fine Wire spark plugs.
