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 the longest and best performance for the price.

BMW N63 4.4L Vent Pipe

The BMW N63 4.4L Vent Pipe addresses common issues with oil separators freezing in cold weather conditions. This problem often occurs if the vehicle is driven before it is fully warmed up, leading to a howling noise and multiple oil leaks. The crankcase breather valve in the vent pipe purges oil vapor from the engine block into the valve cover. However, condensation can sometimes cause the valve to freeze, which may result in the oil separator system failing, cracking, or disintegrating. This replacement vent pipe ensures proper function and prevents costly damage by maintaining the integrity of the oil separator system.

Benefits:

• Prevents Freezing Issues: Reduces the risk of oil separator failure in cold weather conditions.
• Eliminates Oil Leaks: Helps prevent leaks caused by frozen oil separators.
• Ensures Proper Ventilation: Maintains effective purging of oil vapor from the engine block.
• Durable Construction: Built to withstand harsh weather conditions and engine stress.
• Direct Replacement: Designed to fit seamlessly with BMW N63 4.4L engines.

R55-R59 Oil Catch Can Kit for N18 MINI Engines

Introducing the newly updated R55 through R59 Oil Catch Can kit for MINIs equipped with the N16 or N18 engine. This kit includes a "designed-to-fit" stainless steel bracket, mounting hardware, and pre-assembled hoses for easy installation—no drilling or special tools needed. Note: This kit has been redesigned to fit directly behind the outlet of the airbox on the firewall, using the factory tab located on the firewall.

Despite skepticism from "forum experts and social hysteria," an Oil Catch Can (OCC) is essential. Many MINI owners suffer from carbon buildup on their intake valve due to oil being recycled through the intake tract. With the M7 Oil Catch Can, your MINI Cooper's engine will be protected from excessive oil and hydrocarbon buildup, preventing performance-hindering oil film and sludge. Direct injection in 2007 & up MINIs exacerbates the issue, leading to oil blow-by burning onto intake valves, resulting in power loss and expensive repairs.

By capturing excess oil vapor and particles, the M7 Oil Catch Can ensures optimal engine performance. 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
• Eliminates intake tract oil contamination and intake valve damage
• Prevents premature sensor failure
• Maintains engine performance at peak levels
• Carbon Fiber canister with billet bright aluminum top and bottom

The M7 Oil Catch Can is not only functional but also a work of automotive performance ART! It features a 100% carbon fiber housing with CNC machined billet aluminum top and bottom, adding a sharp look to your engine compartment.

All hoses, brackets, clamps, necessary fittings, and easy-to-follow detailed step-by-step instructions are included, along with an oil drain plug and an easy-to-view sight tube. The sight tube allows you to monitor the oil level in the can. The hoses are high-quality "Made in the USA" automotive grade, designed to withstand the rigors of the under-hood environment without degradation.
