About this part

Product Details

NGK is well-known for their ignition components, and their Iridium IX spark plugs are a solid choice for anyone looking to get more out of their engine. These plugs are built with a fine iridium tip, which is six times harder than platinum, giving you a durable and consistent spark. This advanced design helps with improved starting, smoother idling, and a more responsive throttle. They are also treated with a trivalent metal plating, which helps prevent corrosion and makes them easier to remove down the road.

The high melting point of the iridium alloy makes these plugs well-suited for today's engines, contributing to better acceleration and fuel efficiency. You can expect outstanding durability from these plugs, making them a great upgrade over standard nickel alloy spark plugs. They are designed to fit a wide range of vehicles, including many models from the 1970s like the Chevrolet C10, GMC C15, and Pontiac Firebird.
