Autolite APP5245 Plugs sku-3637900721 463637900721

This 6 pc set of Autolite Spark Plugs, model APP5245, is sku-3637900721, UPC 463637900721. The double-platinum design protects both electrodes, reducing gap erosion and misfires and improving durability in distributorless ignition systems, which fire in both directions. A yttrium-enhanced ground electrode transfers heat. Autolite guarantees the plugs for 5 years.

The listing references 1209, 41-805, 7015 and 8123 ignition wire secondary, and fitment for select 1999-2010 Chevrolet Silverado and 2000-2010 Chevrolet Tahoe vehicles. Autolite began making buggy lamps in 1911 and later moved into spark plugs; it says it had made over 10 billion plugs by 2007.

Its range includes iridium, platinum, double-platinum and small-engine plugs for domestic and foreign vehicles.
