High Output Alternator for Mitsubishi Outlander (2011-2012) 2.4L

High-Amp 250A Alternator for 2011-2012 Mitsubishi Outlander (CW5W)

What it Does: The 250A High Output Alternator replaces the factory charging unit on the 2011-2012 Mitsubishi Outlander to supply stable, high-amperage 12V DC power under heavy electrical loads and prevent system voltage drop.

The Stock Mitsubishi Outlander Charging Deficit

Factory charging systems on the CW5W platform utilize a standard 120-amp or 130-amp unit engineered solely for base cabin electronics and basic engine management. When running aftermarket audio amplifiers, auxiliary lighting, overland winches, or external inverters, the factory stator rapidly saturates. At idle and low RPMs, this insufficient output results in chronic battery undercharging, erratic ECU sensor voltages, dimming headlamps, and accelerated diode bridge failure due to persistent thermal overload.

The Engineering Solution

Engineered to resolve charging deficits on the 4B12 engine, this 250-amp alternator utilizes heavy-gauge copper windings and high-grade silicon steel laminations to maximize electromagnetic induction across low-to-mid RPM ranges. Built with an internal heavy-duty bridge rectifier and high-temperature avalanche diodes, it rejects heat build-up while dissipating continuous load demands. The precision-machined rotor and housing bolt straight into factory accessory brackets without bracket modification, directly replacing OEM units such as 1800A288 and A002TX0881A.

Frequently Asked Questions & Fitment Warnings

Does this fit the CW5W Outlander?

Yes, this is a direct fit for the 2011-2012 Mitsubishi Outlander equipped with the 4B12 2.4L 4-cylinder engine; it does not fit 3.0L V6 (6B31) models.

Do I need to upgrade my main power cabling?

Yes, performing a 'Big 3' 1/0 or 4-gauge wire upgrade from alternator to battery positive and chassis grounds is recommended to safely handle 250 amps.
