This 8 pc set of DENSO 3433 SK20HPR-L11 spark plugs is listed under Denso as sku-2131031592, UPC 462131031597. The patented ground electrode produces a larger spark nucleus to support ignition, combustion, throttle response, fuel efficiency, and emissions performance while reducing misfires and erratic starts associated with poor fuel mixtures or soot buildup.

DENSO says the plugs fire leaner mixtures than conventional plugs, are 100 percent pre-fired, last twice as long as conventional plugs, and have a five-rib insulator that reduces flashover and voltage loss. The listing also mentions DENSO's work on direct ignition coils and platinum and iridium aftermarket plugs, along with its Deming Award for Quality, J.D.

Power and Associates Chairman's Award, and supplier quality awards. Listed fitment references are 004 159 13 03, 09482-00606, 12 12 0 032 137, 12 12 0 035 915, 12 12 2 158 253, 12290-RMX-003, 12290-RMX-004, 12290-RMX-013, 12290-RMX-014, 22401 AA630, 22401 AA670, and 22401 AA760.
