DENSO sku-1758830788 461758830781 Iridium TT Plugs

This 8 pc set of DENSO Iridium TT spark plugs is listed as Engine & Powertrain Replacement Parts, sku-1758830788, UPC 461758830781. The plugs are listed as compatible with Ford F-150 5.0L and 5.8L V8 models from 1984-1996. DENSO says the ground electrode creates a larger spark nucleus to support more complete combustion, help reduce misfires and emissions, improve throttle response and ignite leaner fuel mixtures. The plugs are 100 percent pre-fired, have a five-rib insulator intended to reduce flashover and voltage loss, and are claimed to last twice as long as conventional plugs. DENSO also cites its development of direct ignition coils and platinum and iridium aftermarket spark plugs, along with the Deming Award for Quality, the J.D. Power and Associates Chairman's Award and supplier quality awards.
