DENSO 4 pc Iridium Spark Plugs sku-2278214360 462278214365

DENSO Engine & Powertrain Replacement Parts, SKU sku-2278214360, UPC 462278214365. This 4 pc set of iridium long-life spark plugs is compatible with the Honda Accord 2.4L L4 from 2008 to 2012. The patented ground electrode generates a larger spark nucleus to help ignite lean fuel mixtures, support flame travel and reduce misfires and erratic starts caused by poor mixtures or soot buildup. The plugs are designed to improve throttle response, fuel consumption and emissions purification. Each plug is 100 percent pre-fired, has a five-rib insulator to reduce flashover and voltage loss, and is described as lasting twice as long as a conventional plug. DENSO has received the Deming Award for Quality and the J.D. Power and Associates Chairman's Award.
