Denso alternators are not only original equipment on many of the world's top production cars; they are a favorite in motorsports as well, where their light weight, high efficiency, and durability under the most grueling conditions make them the natural choice. Remanufactured Denso alternators go through a grueling process: Stators and rectifiers are tested to 300 volts, while rotors are submitted to 600 volts, all to ensure reliable performance. Rotor slip rings are buffed to an 8 micron surface finish, with runout limited to 20 microns, minimizing brush wear and abrasion. Bearings are validated to OE standards and loaded with premium OE-standard lubricants. New or remanufactured, a Denso alternator is a quality component. Offered in versions from 40 to 160 amperes and beyond for hundreds of specific vehicle applications, all alternators meet Denso's rigorous First Time Fit™ standards.

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.

Awesome Product And Service
I cannot believe its remanufactured. I looks perfectly as new as I saw it in the Lexus parts department with 6 times the price. Works like a champ and soundless spin.
