Denso Aftermarket Products
At DENSO they have taken everything we have learned as an OE manufacturer and applied it to our aftermarket product lines. Every component that leaves our factories has been designed with precision, manufactured to the strictest OE standards and subjected to rigorous safety and performance tests.

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, we've spent over five decades perfecting our technology and processes, a claim that few automotive manufacturers can make.

For decades, DENSO has set and redefined the automotive technology standard. As one of the world's largest automotive component suppliers, OEMs rely on us to help keep them on the leading edge of technology. Our components can be found on thousands of vehicle models for which we produce over hundreds of thousands of unique parts.

In 1972, Denso patented the revolutionary U-Grove spark plug design and the early 1980s we became the first to mass-produce the double platinum spark plug. In the late 1990s, we introduced the ultimate in plug design and performance, the DENSO Iridium spark plug. Originally designed to meet and exceed OE Standards, these plugs were only the beginning of DENSO's expansion into the aftermarket. Following up on the success of the spark plugs, we introduced our First Time Fit® brand of aftermarket components including compressors, starters, alternators, oxygen sensors, fuel pumps, oil and air filters, wipers and more.
