The Dinan Exhaust Valve Remote lets you override the factory exhaust valve operation and fully open (or close) the valve at the press of a button. Directly compatible with 'F' and 'G' chassis BMW's using a single electronic valve as well as 3rd generation MINI's, the Dinan Exhaust Valve Remote Kit is robust in its potential applications. Once installed simply press the top button of the supplied wireless remote to open the valve fully and enjoy maximum aural pleasure. Alternatively, when the need arises for the exhaust to be as quiet as possible, press the bottom button on the remote and the valve will close. This system works with both the factory exhaust and any aftermarket system that utilizes the factory electronic exhaust valve actuator. Tested and compatible valve actuators include BMW P/N's 18307851568, 18308686640, 18308632154, and 18308623424. Features: Opens the factory electronic exhaust valve with the push of a button. Wirelessly remote controlled. Weatherproof housing. Extra length wiring harnesses for maximum application and routing versatility.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Bosch's Oxygen sensors are high quality and will give you the longest and best performance for the price. This is the OEM Bosch oxygen sensor for BMWs with B46, B48, and N74 engines. Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products. As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!
