The product is engineered with extreme precision through 3D scanning technology, CAD design, and CNC machining, guaranteeing perfect fit, maximum durability, and an extremely compact design. It is the ideal solution for a wide range of applications on Jeep models — such as Cherokee, Wrangler, Grand Cherokee — as well as for other custom transmission conversion projects.

This technical solution is created specifically for off-road builds, transmission swaps, and custom applications where strength, precision, and space savings are critical.

Important Note / Technical Requirement:

Due to the extremely compact design, the adapter does not include an intermediate shaft (adapter shaft).

Installation procedure: The transfer case must be disassembled, and the input shaft that meshes with the transmission must be sent to us for spline modification/machining.

Ensure perfect and durable sealing with stainless steel hose clamps (Inox 304). Designed for demanding applications in wet, industrial, sanitary or automotive environments, these clamps with worm-drive mechanism offer excellent corrosion resistance and high mechanical strength. The rounded edge of the band protects hoses against cutting or wear during tightening.

Key Benefits

• 100% Stainless Steel (Inox 304): All components (band, housing and screw) are made from 304 stainless steel, offering superior resistance to rust, moisture and weather compared to standard galvanized clamps.
• Maximum Hose Protection: Raised and rounded edges with smooth inner surface that prevent pinching, damage or cutting of rubber, silicone or PVC hoses.
• Precise Worm-Drive Mechanism: Continuous threaded design allows uniform and smooth tightening without locking, maintaining secure sealing even under intense vibration.
• Versatile Multidrive Screw Head: Hexagonal head with combined slot allows quick tightening with a straight screwdriver or tube wrench (7 mm).

Bosch 0450905021 is a high-quality inline fuel filter designed to protect fuel injection systems by trapping impurities, rust particles, and water before they reach the engine.

Key Features

• High Filtration Capacity: Layered synthetic filter media stops microscopic dirt and water particles.
• Pressure-Resistant Housing: High-strength aluminum construction withstands high fuel system pressures without risk of leaks.
• Corrosion Protection: Exterior coating treated against moisture, chemical agents, and road residues.
• Exact Fit (OEM): Manufactured to original equipment standards for easy installation and perfect sealing.

Unlike standard plastic oil pans — where the filter is cast directly into the pan body — this aluminum pan features a modular design with a detachable and replaceable internal filter.

Key Features and Benefits

• Durable aluminum construction: Manufactured from cast aluminum instead of composite plastic material, offering superior resistance to impact from road debris and stones.
• Enhanced thermal cooling: Aluminum acts as a heat radiator, helping to dissipate transmission oil temperature more quickly.
• Reduced long-term costs (Reusable): Because the filter is not permanently integrated, during subsequent oil changes only the gasket and filter cartridge are replaced, without replacing the entire pan.
• Complete kit: The OEM kit includes the aluminum pan body, dedicated gasket, separate internal oil filter, drain plug, fill plug, and new mounting bolts.

Popular Upgrade (OEM+ Retrofit)

Because standard non-M BMW models (and other vehicles with ZF 8HP transmissions, such as Toyota Supra or standard 3/5 series) come from the factory with disposable plastic pans, this part is frequently used as a direct upgrade. Replacement with this pan allows transition to an easy-to-service filtration system and provides enhanced transmission protection.

Key Features and Technical Specifications

• Automatic Checksum Calculation: Includes automatic checksum calculation for supported engine computers (such as Bosch, Marelli, Delco, Siemens), preventing ECU lockout during writing.
• Tricore & Boot Mode Support: Allows working in Tricore Boot Mode (for microprocessors TC1762, TC1766, TC1796 etc.), useful when rewriting through the OBD2 port is blocked or unavailable.
• Automatic ECU Detection: Automatically identifies the computer type and processor model upon connection.
• Extended Compatibility: Covers a wide range of petrol and diesel vehicles, especially European brands (VAG Group – VW, Audi, Seat, Skoda, as well as BMW, Opel, Fiat, Alfa Romeo).

Main Uses

• Chiptuning & Remapping (Stage 1 / Stage 2): Reading the original file from the ECU, modifying engine maps and writing optimized software back to the computer.
• Special Software Modifications: Cancelling or modifying error codes (DTC), DPF, EGR or Immo Off for motorsport-oriented vehicles.

System and Hardware Requirements

• Housing and Connectivity: OBD2 cable on one end and USB connector for laptop on the other.
• Operating System: Works optimally on Windows 7 (32/64 bit) or Windows 10. Manual driver installation from Device Manager is recommended and temporary antivirus deactivation during installation is suggested.

Writing Caution: During the reading or writing process on the vehicle, battery voltage must be stable (connecting a quality rectifier is recommended). A voltage drop during writing can permanently damage the engine control unit (ECU).
