Features

  • BROAD V6 COMPATIBILITY - for Honda & for Acura: Odyssey (2008-2010 3.5L), Pilot (2009-2011 3.5L), Ridgeline (2009-2011 3.5L), for Acura: TL (2009-2014 3.5L/3.7L), MDX (2010-2013 3.7L), RL (2009-2012 3.7L), TSX (2010-2014 3.5L), ZDX (2010-2013 3.7L)
  • HIGH-OUTPUT 130 AMP POWER: With 130 Amps of reliable power at 12 Volts, this alternator ensures your ignition, fuel system, and high-tech electronics run smoothly. It features a 6-Groove Pulley with Internal Fan (IF) and Internal Regulator (IR) design for efficient cooling and precise voltage control
  • BUILT TO LAST - HEAVY-DUTY CONSTRUCTION: We don't use cheap materials. This unit features robust Aluminum Alloy Die-Cast front and rear covers that resist cracking and deformation. The high-grade stators and rotors provide continuous, stable power generation, while the carbon brushes offer a stronger starting force for instant engagement
  • DIY Installation Tips: The alternator in the 2010 for Honda Odyssey is notoriously cramped. However, since this alternator is compatible with various car models, the tolerances for the mounting holes may vary slightly. If you have trouble threading the bolts, don't worry. You've purchased the correct part. Simply enlarge the bolt holes by 1-2 mm
  • DIRECT REPLACEMENT - PLUG & PLAY: This is a brand-new unit, not a remanufactured core. It bolts directly into the stock mounting points and connects to your factory wiring harness without modifications (see installation note above regarding bolt hole sizing)

  • Thank you for being affordable.
Works. Hope it lasts a long time. I had to grind down a bushing on the alternator in order for the lower bolt arm to fit in its slot on the engine. I probably took a full 1/16 inch off with the bench grinder. The alternator I replaced also had the same place ground down! I guess this isn’t the first time it’s been replaced. 205k miles and ticking on this 2011 Honda Pilot. ... show more

  • Great on 2011 Honda Pilot Touring Great on 2011 Honda Pilot Touring
Fit great on 2011 Honda Pilot Touring. Had to smack the grommet thing on the larger bolts hole as it was out abit just but it had a bit of gap in it to be smacked. Also the nut on the that goes under the washer type connection (then you put another nut on top) was too tall so I reused the stock one. Other then them things charges great and all connections were snug and plugged in exactly how they should. ... show more
