Product Advantages

Alternator matching focuses on amperage, voltage, pulley configuration, regulator/fan design, plugs, and OE replacement references.

Fitment-first matching

CF-20491N is prepared for alternator sourcing with Part No, OE, Lester number, and application records checked together.

Quality and test focus

Core specifications such as voltage, power or amperage, rotation, teeth, and design are reviewed before sample or bulk quotation.

Replacement sourcing support

MFR DENSO and replacement references including 20491 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Share target quantity, destination, sample need, and packaging requirement so Crankvia can confirm the practical supply path.

Application Information

Application records are provided as compatibility references. Confirm OE number, vehicle configuration, engine, and market version before final ordering.

How do I confirm CF-20491N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Land Rover - Europe DISCOVERY IV (LA_) Eng.306DT, 30DDTX 3.0 TD 4x4 155kw, Land Rover - Europe RANGE ROVER SPORT (LS_) Eng.30DDTX 3.0 D 4x4 180kw and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 150A, Rotation: CW, Regulator/Fan: IR/IF, then cross-check OE numbers Denso 104210-2420, 104210-2421, 104210-2422, Ford AH22-10300-AB.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 20491. That usually narrows the match quickly.
