BMW F22 M240i Upstream Oxygen (O2) Sensor

SKU F22-M240I-O2U
Price

$129.99

The upstream oxygen sensor measures exhaust gas before the catalytic converter, helping the engine computer fine-tune the air-fuel mixture. A worn sensor can hurt fuel economy and trigger a check engine light.

This O2 sensor is designed to fit the BMW F22 M240i (N55 turbo inline-six), matching the factory thread size and connector.

Accurate, OEM-matching design restores proper fuel trims and clean, efficient running.

Reference: OE/interchange ULTRA-POWER

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
