A-Premium 2-Pack O2 Oxygen Sensors for Toyota & Lexus — Heated 4-Wire, Direct-Fit

If your check engine light points to an O2 sensor or your vehicle shows poor fuel economy or rough idle, these A-Premium oxygen sensors offer a direct-fit, threaded replacement for a range of Toyota and Lexus vehicles from the mid-1990s through the early 2000s. Each kit contains two heated, 4-wire sensors built to the original connector gender and length so you can swap them in without modifying wiring or harnesses. The sensors arrive boxed and include part numbers that match common OEM references, simplifying verification before purchase.

Which vehicles do these sensors fit?

These sensors are designed to be compatible with specific Toyota and Lexus models and engine types across several model years. Fitment covers SUVs, pickups, and trucks with 4-cylinder, V6, and V8 engines; always confirm vehicle year, engine displacement, and connector orientation before ordering. Use the seller's vehicle selector and the listed reference numbers to ensure proper match.

• Lexus LX470: 1998–2005, V8 4.7L
• Toyota 4Runner: 1996–2000 (L4 2.7L, V6 3.4L)
• Land Cruiser: 1998–2005, V8 4.7L
• Pickup/Tacoma/Tundra/Sequoia/T100: fits various years and 2.4L–4.7L engines listed in product details

What are the sensor specifications and how do they install?

Each unit is a threaded, heated oxygen sensor with a 4-wire design and a 450 mm overall lead length, ending in a male connector to match factory harnesses. Installation is straightforward for anyone comfortable working under the vehicle; the threaded mount replaces the old sensor, and no special tools or wire splicing should be required when the correct part is selected.

• Wire quantity: 4 (heated element and signal/ground wires)
• Overall cable length: 450 mm
• Mounting: threaded — installs into existing exhaust bung
• Connector gender: male — intended to mate with factory female sockets

How do I confirm I’m ordering the right part for my car?

Before buying, check multiple identifiers: the vehicle compatibility list, the sensor reference numbers, and the physical connector type on your vehicle. The product lists common OEM reference numbers that help match cross-references; when in doubt, use the listing’s vehicle selector or contact the seller with your vehicle VIN for confirmation.

• Reference numbers: ES20072, 250-24154, 234-4161, 25024154, 2344161
• Compare your old sensor: 4 wires, threaded mount, male connector
• Enter year, make, model, and engine in the listing before ordering
