Keep crankcase vapors in check and your intake air clean with the BMS Oil Catch Can Oil Filler Cap Dual Vent Connection Kit for the Gen2 B58. This upgrade ditches the flimsy factory venting in favor of a precision CNC-machined billet oil filler cap and dual-vent fittings engineered to handle increased crankcase pressure under boost. By diverting oil-laden vapors into a catch can instead of back through the intake, this system helps minimize carbon buildup, reduces oily contamination, and promotes more consistent performance as power levels climb. High-quality hoses and fittings ensure a secure, leak-free install that won’t collapse under pressure and maintains a clean, OE-plus appearance in the engine bay. An easy, effective upgrade for B58 enthusiasts looking for cleaner operation, improved engine longevity, and proven performance-focused design

This is a complete plug and play solution to replace your stock Low-Pressure Fuel Pump (LPFP) with a new E85 certified bucketless assembly.

This solution provides up to 25% more flow than our standard Stage 2 LPFP upgrade and up to 150% more flow than the stock pump.

This pump will support up to 550whp running 85% ethanol and 600whp running 50% ethanol.

The Stage 2 bucketless kit includes the following:

- A custom anodized billet fitting for the pump output and stock fuel line connection.
- Our custom billet aluminum anodized bracket for the pump and float assembly
- Two cotter pins to secure your float assembly
- A new E85 compatible Walbro 450 pump
- Spare vent tube clip
- A new Walbro filter

If you still need more flow, the Stage 3 upgrade is also available and can be added to your Stage 2 bucketless pump.

The Stage 3 upgrade kit includes:

- A complete plug and play solution by simply adding the secondary module
- Our custom billet aluminum fitting to run both pumps in parallel
- A new E85 compatible Walbro 450 pump
- Wiring harness for the secondary pump
- Spare vent tube clip
- A new Walbro filter

Recommended accessories:
- Lock Ring Removal Tool
- Hobb's switch
NOTE: These kits include a basic filter assembly. When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump. In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns. Again for those applications we'd recommend one of our standard pump applications.

Features & Benefits: Direct-fit adapter harness & mounts for straightforward B58 coil installation Plug-and-play design — no cutting, splicing, or permanent modifications Secure coil seating & alignment for consistent performance and reliability Improved ignition stability under high-load or tuned conditions, helping reduce misfires Applications: Stage 1–3 N55 builds, turbo upgrades, ethanol blends, track use, and aggressive daily driving Drivers looking to eliminate heat- and boost-related ignition issues Anyone seeking an OEM+ quality coil upgrade without a messy DIY install Result: A clean, professional installation that modernizes your ignition system and delivers reliable spark performance under all conditions. If you provide the kit’s brand/part number and whether your valve cover is stock or aftermarket, I can refine this description for precise fitment and application.

Standard Kit Includes: A brand new OEM LPFP bucket that is upgraded with a new Walbro 450 or 525 pump and filter. A new E85 compatible Walbro 450 pump (F90000274) that flows 50% more fuel than stock Optional A new E85 compatible Walbro 525 pump (F90000285) that flows 65% more fuel than stock NOTE: Owners with I-Drive may get a Fuel pump warning on the screen that says "Continued driving is possible. Have the system checked by your BMW center as soon as possible." As long as the car is running fine and does not exhibit any other symptoms, there is not an issue with the pump and this can be ignored. If you have any questions about this please feel free to contact us. Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced. If this is a concern for you check out our Stage 3 fuel pump upgrade kits that retain the stock LPFP and add a secondary pump.

Clean, Safe Installation: Includes a 12 V adapter and inline fuse for hassle-free integration. How it works: This harness links your JB4PRO tuner to your flex fuel hardware. It’s not a complete flex fuel kit—you still need a compatible ethanol sensor—but it gives your JB4PRO the accurate readings it needs to adjust timing, boost, and fueling for E30, E50, or E85 blends.

This is a complete plug and play kit to install a Bluetooth ethanol sensor in your E-Series BMW. (Check compatibility for your platform below) This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgrade -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer to monitor your ethanol content. This kit features a 0-5 volt analog output that integrates with the JB4, analog gauge, or any other ECU or tuner that supports 0-5 volt input. All of these kits utilize a custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed. For your fuel line upgrade, choose the option that supports your current configuration. HPFP to the fuel tank: (Stock) This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor. Port Injection to the fuel tank: If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel. Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup. Non-Fuel-It! port injection to fuel tank: Choose this option if you are running a port injection kit that we did not manufacture or sell. This kit includes a longer 18" feedline from the Y to the port injection rail. You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail. *These kits are available for off-road use only *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated. *For the BMW N54 E-series JB4 platform connect the white wire to position #15 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *For the BMW N55 E-series JB4 platform connect the white wire to position #16 on the JB4 25 pin harness.

Keep heat where it belongs and boost where it counts with a B58 Turbo & Intake Heat Shield for BMW and Toyota Supra—an OE-plus style upgrade that helps your setup stay cooler, more consistent, and happier when you’re leaning on it. BMW’s factory heat management is fine at stock-ish levels, but once you start turning the wick up, the turbo becomes a rolling space heater. That radiant heat soaks the nearby intake tract, nudging IATs up and making performance less repeatable pull after pull. This shield steps in as a dedicated barrier between the turbo and intake components, helping reduce heat soak so you can keep intake air cooler and denser when you’re driving it like you mean it. Built with a clean, factory-inspired mindset, it’s precision-formed to wrap neatly around the B58 turbo and intake area, and it mounts using factory locations for a tidy, OEM-level install. No cutting, no permanent changes, and fully reversible—just a straightforward bolt-on that looks right at home in the engine bay. Made from durable, heat-resistant materials, it’s designed to handle the heat long-term without turning into a crispy science project. Why it matters Cuts down radiant heat from the turbocharger into the intake area Helps reduce intake air temperature creep Improves consistency during repeated pulls and hard driving Adds protection for surrounding components exposed to turbo heat Features & highlights Designed for BMW B58 and Toyota Supra applications Precision-formed for OEM-level fitment Heat-resistant construction for long-term durability Bolt-on install using factory mounting points Clean, OE-plus under-hood appearance

Free Up Real S65 Power — Engineered the Turner Way Your S65 is already making the power. This kit simply lets you keep more of it. The Active Autowerke Power Pulley Kit for the BMW E9X M3 reduces parasitic drag at the crankshaft, trimming rotational mass and freeing up horsepower that would otherwise be consumed by accessory drive load. The result is a measurable increase in rear-wheel output without sacrificing the balance, cooling capacity, or long-term durability expected from a properly engineered BMW upgrade. The crank pulley is CNC-machined from billet 6061 aluminum and finished with a hard-coat anodize for durability under sustained high-RPM operation. Unlike undersized pulleys that compromise system function, this design maintains proper operating characteristics while delivering real-world gains. Late-2007 production E9X M3 models transitioned to a double-sided (DPK) A/C belt configuration. Rather than forcing a workaround, Active Autowerke developed a proper DPK-compatible solution — including the correct matched belt. Applicable kits also include a spare DPK belt for added insurance. Dyno testing on a Mustang chassis dyno confirms gains of 10–12+ rear-wheel horsepower on an otherwise stock vehicle. Installation is fully reversible and requires no permanent modification. Product Highlights 10–12+ RWHP gain verified on stock S65 engines Complete bolt-on system CNC-machined 6061 billet aluminum crank pulley Hard-coat anodized finish for durability Includes correct replacement drive and A/C belts Spare DPK belt included where applicable Compatible with manual and DCT-equipped E9X M3 Reduces parasitic drag and rotational mass Designed to maintain proper operating temperatures Works in conjunction with Active Autowerke performance software Available for single-sided and double-sided (DPK) belt configurations Fitment Information Confirm whether your E9X M3 is equipped with a single-sided or double-sided (DPK) A/C belt prior to ordering to ensure correct application. A properly engineered solution for enthusiasts who want measurable gains while preserving OEM-level refinement and reliability.
