Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.

Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.

Kit contents:

Lower temperature thermostat - 70c (158F) vs Factory 110c (230F)
Low temp thermostat spring

Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure.

For the BMW enthusiast seeking an aggressive upgrade for their 2010–2012 X5M or X6M without the drawbacks of "stinky" exhaust or frequent error codes, Active Autowerke offers the Aflow Catted Downpipes. These units provide the performance benefits typically associated with track-only pipes while maintaining high-flow catalytic efficiency. This design prevents the raw fuel odor and excessive cabin drone often found in catless setups, making them the ideal choice for a performance-oriented daily driver. Each set is custom-made in Miami, ensuring an exact, surgical fit to the factory mounting points. By utilizing high-quality casted V-band flanges and premium materials, these downpipes offer a reliable, leak-free solution that enhances the sophisticated V8 exhaust note without triggering the Check Engine Light (CEL). Key Features: No CEL Guarantee: Advanced Aflow catalyst design avoids catalytic efficiency warnings on the dashboard. Refined Exhaust Note: Enhances the natural V8 growl while maintaining high-end luxury refinement. Cast V-Band Connections: Precision upper flanges ensure a perfect, factory-like seal to the turbo housing. Direct Bolt-On: Replaces bulky OEM ceramic converters with no cutting or welding required. Thermal Management: Efficiently handles the high heat output of the BMW twin-turbo V8 platform. U.S. Manufacturing: Fabricated in-house to meet Active Autowerke’s high standards of quality control. Specifications: Primary Material: TIG-Welded 304 Stainless Steel. Manufacturing Location: Miami, FL, USA. Inlet Type: Casted Stainless Steel Flange. Weight Reduction: Significantly lighter than the heavy factory ceramic catalytic assemblies. Finish: Industrial brushed stainless. Build Time: Custom made-to-order (Approx. 2 weeks).
