Ensure optimal engine performance with the Bosch Oxygen Sensor, an OEM replacement part suitable for your Mini. Designed to measure the amount of unburned fuel in the exhaust pipe, this sensor helps adjust fuel mapping for reduced emissions and improved fuel economy. When your engine triggers an oxygen sensor check engine light, replacing it with this unit is crucial. Malfunctioning sensors can lead to decreased MPG and performance, but with easy replacement, you can quickly restore your Mini's performance and mileage. Apply anti-seize on the threads during installation to prevent it from sticking permanently. Regular maintenance is recommended as oxygen sensors tend to fail slowly. Mounts at the rear behind the catalytic converter.

• OEM Bosch replacement for optimal performance
• Measures unburned fuel for improved fuel economy and reduced emissions
• Easy replacement restores performance and mileage quickly
• Application of anti-seize prevents permanent sticking
• Regular maintenance recommended for prolonged sensor lifespan

M7 Oil Catch Can Kit for MINIs

Newly Updated Kit for Improved Engine Performance

The newly updated R55 through R59 Oil Catch Can kit for MINIs equipped with the N16 or N18 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.

Why You Need an Oil Catch Can

"Forum experts and social hysteria" may say an OCC is not needed, but we beg to differ. Many MINI owners suffer from carbon buildup on their intake valve due to 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.

This oil film & sludge can appear in other critical places throughout the engine, such as the intercooler and the MAF sensor (Mass Air Flow), where clean surfaces are critical for maximized heat transfer and engine performance.

Features and Benefits

• Prevents intake tract oil contamination and intake valve damage
• Prevents premature sensor failure
• Keeps engine performance at peak levels
• Increases flow area by 77% for improved oil separation
• Includes billet aluminum oil catch can with coalescing oil separation technology and integrated dipstick
• Comes with two molded oil-resistant silicone hoses with STS technology (available in Red or Black)
• Includes installation hardware kit and printed instructions
• 100% carbon fiber housing with CNC machined billet aluminum top and bottom

Easy Installation

With our exclusive "Exact-Fit" pre-assembled hose kit and brackets, installation is super-easy. All hoses, brackets, clamps, necessary fittings, and easy-to-follow detailed step-by-step instructions are included. An oil drain plug and an easy-to-view sight tube are also provided, allowing you to monitor the oil level in the can.

Beware of other "low-cost" catch can systems that use silicone hoses, as oil and silicone are not compatible and silicone hoses will eventually deteriorate, causing a mess in your engine compartment. Access Secret Premium Dashboard

For your BMW's optimal performance, ensure the functionality of the hose connecting the oil dipstick to the crankcase vent valve. Positioned below the intake manifold, this hose is susceptible to clogging with oil film and condensation, leading to potential failure over time. Cracks and swelling in old hoses can result in oil and vacuum leaks, compromising engine performance.

• Essential component for BMW engine functionality
• Prevents clogging and potential hose failure
• Minimizes oil and vacuum leaks
• Convenient replacement when replacing crankcase vent valve
