Toyota 1UR-FE (4.6L gasoline)
Max-Amp alternators are designed for heavy-duty / commercial use and are the premier alternator on the market. A Max-Amp alternator will fit your needs, whether your demands are for:
- High amperage (continuous or intermittent)
- Extremely hot conditions (Death Valley hot)
- Stable, high amperage whether idling or at road speed
- High humidity, water, chemicals, etc.
This Max-Amp heavy-duty alternator vastly outperforms the stock Toyota alternator, both at idle & at road speed. Note on the chart below to see the performance differences.
OEM Alternator Max-Amp Alternator
Amps @ Idle 90 amps 200 amps
Amps @ Road speed 150 amps 270 amps
The XP series of Max-Amp alternators are assembled using DENSO components and produce the highest idle output. They feature a larger housing while still retaining OEM fitment without any modification required. They run cooler and are virtually indestructible. This alternator is designed to be an exact replacement to the OEM alternator for the 1VD engine.
A precision CNC 6061T6 aluminum pulley with a .002 hard anodized coating is installed on each alternator for maximum output and durability. This XP Series alternator comes with an unprecedented full two-year warranty.
