NGK Toyota 4Runner 1989-1988 Direct Fit Oxygen Sensor

NGK is known worldwide as a top supplier of original equipment oxygen sensors, and this direct-fit sensor is built to the same standards. Your 1988 or 1989 Toyota 4Runner relies on this part to keep the engine running smoothly, get the best possible gas mileage, and keep emissions in check. It works by sending constant feedback to your vehicle's computer about the air-fuel mixture, helping it make adjustments on the fly.

This sensor uses an advanced ceramic element that's designed to resist contamination and deposits, which can often cause other sensors to fail prematurely. NGK controls the entire manufacturing process, from the raw materials to the finished ceramic element, ensuring a well-built part that fits right and performs as expected. When your check engine light comes on, or if you're just looking to keep your older 4Runner running its best, a new oxygen sensor from NGK is a solid choice.
