Product Details

Original U-Groove Spark Plug by Denso®. DENSO's patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures.

The Denso Iridium Long Life plug is fast becoming the standard for today's high-tech engines. Properties of Denso's patented Iridium alloy have broken through the spark plug technology barrier. Employing a revolutionary new 360° laser-welding process, Denso has created a spark plug unlike anything on the market today. Designed for durability under the most extreme conditions, Denso's patented Iridium alloy is six times harder and eight times stronger than conventional Platinum and can handle temperatures in excess of 4,000°F.

Denso® factories are QS9000 and ISO9000 certified worldwide, just one of the many reasons why zero defects for parts produced in the millions is a reality for Denso. A recipient of the prestigious Deming Award for quality in 1961, Denso spent over five decades perfecting technology and processes, a claim that few automotive manufacturers can make. Denso First Time Fit™ products — including A/C compressors, starters, alternators, oxygen sensors, ignition wire sets, fuel pumps, cabin air, oil and air filters, wiper blades and more — are products built and tested to OE-standard offered for the aftermarket by Denso. Each of these products is precision-built for exact replacement so you don't have to worry about doing the same job twice.
