NGK Spark Plug for Saab 900 (1985–1998) and Saab 9000 (1986–1989)

NGK spark plug 5689 is an aftermarket ignition plug for the Saab 900 and Saab 9000, covering S, SPG, Turbo, Turbo Commemorative Edition, and CD trims. A spark plug threads into the cylinder head and fires the air and fuel charge in the combustion chamber, so each cylinder relies on its plug for clean starts and steady running. NGK is a brand of Niterra Co., Ltd., a Japanese company founded on October 26, 1936, and headquartered in Nagoya. Niterra builds spark plugs and related products for internal combustion engines, along with technical ceramics.

This NGK spark plug carries a warranty of 24 months or 24,000 miles.

Niterra supplies NGK and NTK products to vehicle manufacturers as original equipment and also sells them to the aftermarket. On the Saab side, this plug applies to the 900 and the 9000, including both naturally aspirated and Turbo versions of the 900. Because the 900 coverage skips some model years, check the exact year and trim against the fitment table rather than assuming every 900 from the period is included.
