DENSO 210-1149 First Time Fit Remanufactured Alternator

The DENSO 210-1149 is a remanufactured alternator built to DENSO's rigorous First Time Fit® standards — the same quality benchmark used on original equipment components supplied to the world's leading automakers. Designed to handle the demanding electrical loads of modern vehicles, this alternator delivers reliable charging performance right out of the box with no fitment guesswork.

Every remanufactured DENSO alternator undergoes an intensive reconditioning process. Stators and rectifiers are tested to 300 volts, while rotors are subjected to 600-volt insulation testing to verify performance integrity. Rotor slip rings are precision-buffed to an 8-micron surface finish with runout controlled to within 20 microns — minimizing brush wear and extending service life. Bearings are validated to OE specifications and packed with premium OE-grade lubricant.
