One of the true innovators in electronic fuel injection technology, DENSO introduced the 12-hole injector in 1999. Its breakthrough design reduced fuel droplet size to 65 microns, providing superior atomization for improved engine efficiency. In 2002, DENSO followed with its UC injector, reducing droplet size even further, down to 50 microns - around one-half the width of a human hair. That same world-class engineering expertise goes into DENSO's entire line of First Time FitŪ fuel injectors. Added-value materials and innovative features like welded seals allow DENSO injectors to meet the most rigorous emissions requirements in the world, including those for Super Ultra Low Emissions Vehicles (SULEV) and Partial Zero Emissions Vehicles (PZEV). A DENSO fuel injector is a precision instrument - they're that accurate.
While the electronic fuel injection systems in today's cars are incredibly sophisticated and can adapt to a wide range of conditions, their real-world performance often comes down to the accuracy and consistency of the injectors themselves. Each injector must deliver precisely the right quantity of fuel at exactly the right instant, thousands of times per minute, or performance, economy, and engine smoothness will suffer. The top parts distributors, retailers, and technicians won't settle for second-best on these crucial components. That's why they select DENSO First Time Fit® fuel injectors.
Lowest Emissions Standards DENSO First Time Fit fuel injectors meet the lowest emissions standards, including Super Ultra Low Emissions Vehicle (SULEV) and Partial Zero Emissions Vehicle (PZEV).
