Infiniti I35 High Output Alternators

Quiet, front-drive and powered by a smooth 3.5L V6, the 2002-2004 Infiniti I35 is still a commuter for owners who value a well-built sedan. This Infiniti I35 high output alternator is the 400 amp Mechman unit listed for the I35, replacing a worn original and adding headroom for the modern electronics a twenty-year-old car never planned for.

Front-Drive Comfort, Modern Electronics

When the I35 was new, the biggest electrical load was the factory stereo. Today its owners add a touchscreen head unit with smartphone integration, a backup camera, a dash cam, a small amplifier and USB-C chargers for everyone. On top of that, an original alternator with two decades of heat cycles is simply worn. An Infiniti I35 high output alternator at 400 amps fixes the reliability problem and covers every addition, so the car keeps commuting without a surprise battery light.

Fitment Notes

The billet unit here is listed for 2002-2004 I35 models with the 3.5L engine. Confirm year and engine in the vehicle finder above before you order. The same alternator appears on our Infiniti I30 and Nissan Murano pages. Mechman high output alternators install in the factory position, but on an older car it is worth checking the connector too; our harnesses and regulators cover that.
