Bosch Oxygen Sensors - Bank 1 And 2 Pre-Cat - N52

Product Details

Your engine's air fuel ratio needs to be dead on. Worn out factory pre-cat oxygen sensors delay vital data to the DME, leading to sub optimal fueling, lost horsepower, and dangerous hesitation under load.

We put together this Turner Pre-Cat O2 Sensor Refresh Kit using track-proven Bosch hardware to keep your BMW running at its absolute limit. Positioned right in the exhaust manifolds, these sensors give your engine management system the real-time data it needs to maximize combustion efficiency and unleash every available pony. Don't let a pair of neglected sensors compromise your tune or your track day. Swap them out, restore your power curve, and drive with confidence.

Kit Includes:

• Bosch Bank 1 Pre-Cat O2 Sensor

• Bosch Bank 2 Pre-Cat O2 Sensor
