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.

This is a Bosch O2 sensor - also known as a Lambda probe. Bosch is an OEM supplier to BMW.

Position: after the catalytic converter (post-cat).

Upgrade your MINI with the M7 Oil Catch Can Kit__xxSTARTxx__/h1

The newly updated R55 through R57 Oil Catch Can kit for MINIs equipped with the N14 engine comes with a "designed-to-fit" stainless steel bracket, mounting hardware and pre-assembled hoses. Installation is super easy...no drilling and no special tools are needed. NOTE: This kit has been redesigned to fit on the firewall directly behind the outlet of the airbox. It uses the factory tab located on the firewall."Forum experts and social hysteria" say an OCC is not needed but we beg to differ. Why do so many MINI owners suffer from carbon buildup on their intake valve? The answer is oil being recycled through the intake tract to be burned. With the M7 Oil Catch Can, your MINI Cooper's engine will be protected from excessive oil and hydrocarbon buildup which leads to performance-hindering oil film and sludge along your intake tract, on your engine control sensors and on your engine's intake valves. Because the 2007 & up MINI is direct injection the intake valves do not benefit from the cleaning action provided by the gasoline as in older port injection engines. Now all the oil blow-by burns onto the intake valves and builds up into a flow choking hydrocarbon mess. The end result is loss of power and a very expensive repair bill. This oil film & sludge can appear in other critical places throughout the engine-- such as the intercooler-- where clean surfaces are critical for maximized heat transfer and on your MAF sensor (Mass Air Flow) where the film will cause the sensor to send a false signal to your ECU killing performance.

By capturing excess oil vapor and particles, the M7 Oil Catch Can ensures that oil film and sludge will not become a factor in your vehicle's performance. If you don't think your engine is pumping oil back through your intake system, remove the breather tube and look at all the oil!. The breather tube connects directly to you intake hose and directs this oily mess back through your engine to be burned.

Now with our exclusive "Exact-Fit" pre-assembled hose kit and brackets installation is super-easy.

Features:

• Pre-assembled hose assemblies.
• Stainless steel bracket and mounting hardware
• Eliminate intake tract oil contamination and intake valve damage.
• Prevent pre-mature sensor failure
• Keep engine performance at peak levels
• Billet Aluminum Construction
• Bright Black Anodized Finish
• Laser Etched M7 Logo

The M7 Oil Catch Can is not only functional is a work of automotive performance ART! It is CNC machined from billet aluminum and adds a sharp look to your engine compartment.

All hoses, brackets, clamps, necessary fittings and easy to follow detailed step-by-step instructions are available on this page in .PDF format. The design includes an oil drain plug and an easy to view sight tube which indicated the oil level within the can. The hoses are high quality "Made in the USA" automotive grade designed to withstand the rigors of the under-hood environment and to not degrade when exposed to oil. Beware of other "low cost" catch can systems that use silicone hoses because oil and silicone are not compatible. Silicone hoses will will eventually deteriorate and make an absolute mess of your engine compartment.
