BMW B46 B48 Motiv ReFlex Plug-n-Play Ethanol Sensor Harness simplifies the integration of an ethanol content sensor into your BMW's Re|Flex system. This harness is designed to enhance your vehicle's performance by scaling the sequential port injection based on real-time ethanol content, eliminating the need for manual adjustments. Key benefits include:

  • Effortless Installation: Plug-n-play design makes it easy to connect an ethanol content sensor without extensive modifications.
  • Real-Time Adjustments: Allows for automatic scaling of port injection based on real-time ethanol content, optimizing engine performance.
  • Seamless Integration: For CANbus integrated vehicles, it facilitates integration with the factory DME/ECU (pending feature release by tuning platforms).
  • No Manual Flashes Required: Removes the need for ground disconnection or map switching on your port injection controller.

Please note that the ethanol sensor is not included with this harness.

These adapters are machined from high-grade aluminum and anodized for corrosion resistance. QDAs incorporate Viton© o-rings which are compatible with most types of fuel, solvents and oils. QDAs maintain a reliable leak-proof seal under normal fuel injection system operating pressures. This particular QDA is sized perfectly to adapt right between the fuel line you were going to connect to your ethanol sensor. 3/8" (9.5mm) female quick disconnect 3/8" (9.5mm) male quick disconnect 1/8" Female pipe thread port * Viton© o-rings Crecent-lock system E-85 compatible Black anodized aluminum

When building a car for the track, one of the most important factors to consider is weight. Stock batteries can weigh up to almost 50 pounds and are unnecessarily large, designed to power a host of systems not normally used in a track car (radios, lighting, etc.). What can you do to cut weight the weight without affecting your car's operation? This is where Braille Battery comes in with their long line of performance lightweight battery options! Designed to provide the highest cranking power possible while being up to 75% lighter, Braille Battery is one of the foremost leaders in automotive racing batteries with nothing but high quality, high output batteries in mind! The B3121 battery from Braille is their lightest do-everything battery available, offering 1380 pulse cranking amps that can crank over V8 engines with ease while still coming in at under 22 pounds, half of the weight of a standard Group 34 battery! This is thanks to their Advanced AGM racing technology that allows them to put a ton of power into a very small package. Physical Specifications: BCI Group: All sizes Weight: 21lbs / 9.5kg Length: 6.6" / 168mm Width: 5.2" / 132mm Height: 6.8" / 173mm Polarity: Right Side Positive Terminal Type: Steel terminal block with M6 bolt Performance Specifications: Voltage: 12v Recharge Voltage: 14.4V – 14.6V Maintenance charge voltage: 13.8V 5s Pulse Cranking Amps (PCA): 1380 10s PDC: 124 Amp Hour (Ah): 31 Watt Hour (Wh): 372 Life Cycle @ 10% DOD: 3100 Charging Temperature 0C to 50C Discharge Temperature range -40C to +60C Storage temperature -40C to +60C *THIS BATTERY REQUIRES A CUSTOM MOUNTING SOLUTION. The size and weight are significantly smaller than a stock battery and will not be held in place by the stock battery mount*

Presenting the perfect addition to our X5M, XM intake system to optimize the flow path all the way to the turbos. Our carbon inlets have a larger volume than the stock inlets by maintaining a larger diameter all the way to the turbos. The stock inlets narrow down immediately after the connection to the intake which creates a restriction especially at higher boost levels. We have alleviated this restriction and also designed the curvature to be as smooth as possible allowing the turbos to function with reduced resistance. Made from prepreg carbon fiber with CNC machined flanges, the inlets also provide an aesthetic improvement to the engine bay. Benefits of the inlets are apparent with tuned vehicles where the boost pressure is higher and therefore the flow demand form the turbos is greater. This is where the larger volume of the carbon inlets help provide that extra flow. The performance gains are produced from providing the turbos with a less resistive flow path which allows them to reach peak boost sooner in the RPM range. When comparing to the stock inlets the differences are clear to see. Where the stock tubes narrow down immediately after the connection to the intakes, our tubes maintain a larger diameter and the reduction to the stock turbos is achieved with an internal radius on the machined flanges. This allows for larger volume whilst maintaining a smooth flow path. One of the drawbacks of the oversized inlets was the more aggressive reduction in size to match the stock turbos which created some flow constraints. NOTE: Some photos show our optional F9X X5M / X6M / G09 XM / G0X M60i Intake system available separately. Each inlet inlet set consists of: Prepreg Carbon Inlet Pair CNC Machined Turbo Flanges CNC Machined Breather Valve Assembly Compatible Models: F95 X5M Pre-LCI F96 X6M Pre-LCI G09 XM Pre-LCI G05 X5 M60i Pre-LCI G06 X6 M60i Pre-LCI G07 X7 M60i Pre-LCI ** This item is not eligible for return **

Maintaining proper oil levels in your engine is crucial for peak performance. Undetected leaks can cause your oil to drop to dangerously low levels between oil changes, leading to severe engine damage.

One common culprit for oil leaks is the valve cover. Over time, exposure to extreme temperature fluctuations can wear down the gaskets, causing them to fail. Prevent oil leaks and protect your engine by replacing these vital components.

Comprehensive Kit Includes:

Valve Cover Gasket Set - Left & Right High Pressure Fuel Pump Gasket (2) O-Ring Seals (6) Torx Screws (6) Replace your old gaskets with our high-quality kit to keep your engine running smoothly and efficiently.

If your engine has higher mileage, don't neglect rod bearing replacement! These bearings are sandwiched between the connecting rod and crankshaft journal and are prone to failure due to overheating, lack of lubrication, or general wear. Replace your rod bearings and prevent a spun bearing.

Starting with ACL’s high-performance bearing shells, our Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Kit includes

Turner Motorsport WPC-Treated Race Series Rod Bearing Shells (16) Genuine BMW Connecting Rod Bolts (16) Hardware for Oil Pan & Oil Sump Oil filter Liqui-Moly Molygen 5W-40 (6L) Drain Plug Turner Motorsport Oil Reminder Sticker Oil pan gasket RedLine assembly lube (4 oz.)

Maintaining proper crankcase ventilation and positive oil retention is crucial for the performance and longevity of BMW’s high-output twin-turbo 4.4L V8 engines. Extreme engine bay heat cycles cause original plastic covers to warp and internal PCV components to degrade, compromising engine seals and vacuum pressures.

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug. To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance! See kit contents below for a complete list of included components.
