Fuel Coarse Filter – A high‑capacity filtration device that removes large particles, water, and contaminants from diesel fuel before it reaches the high‑pressure injection pump. Manufactured with a durable steel canister and a pleated synthetic media with a controlled micron rating (typically 10‑15 µm absolute), this filter ensures that only clean fuel enters the fuel system. Its integrated water separation feature collects moisture that can cause corrosion and injector damage, and a built‑in drain valve allows for easy water removal. The filter is designed for spin‑on replacement, making maintenance quick and straightforward. This fuel coarse filter is a direct replacement for the original factory component, offering identical flow and filtration characteristics. It is critical for protecting the injection pump and injectors from premature wear, ensuring consistent engine performance and fuel economy. Regular replacement at the recommended interval (typically every 30,000‑50,000 km) is essential. This filter is an integral part of the WP12 fuel system, and its high‑quality construction ensures long‑term reliability even in the presence of poor‑quality fuel. Its robust design withstands fuel pressures up to 10 bar and temperatures up to 100°C, making it suitable for the most demanding operating conditions.

Hexagon Screw Plug – A precision‑machined threaded plug used to seal oil, coolant, or fuel ports in the engine block, cylinder head, or other components. Manufactured from high‑strength alloy steel with a zinc‑plated or zinc‑nickel coating for corrosion resistance, this plug features a precision‑cut thread that provides a tight, leak‑free seal. Its hexagonal head allows for easy installation and removal using a standard socket or wrench, and many variants include an integrated sealing washer or O‑ring for enhanced sealing performance. The plug is designed to withstand high pressures (up to 150 bar) and temperatures up to 150°C, ensuring reliable operation in harsh engine environments. This hexagon screw plug is a direct replacement for the original factory component, offering identical thread dimensions, sealing characteristics, and material strength. It is essential for maintaining the integrity of fluid systems, preventing leaks that could lead to loss of oil pressure, coolant loss, or fuel contamination. Regular inspection for corrosion or thread damage is recommended, and replacement is advised if any signs of wear are detected. This plug is a versatile and durable component, used in various locations on the WP12 engine, and its high‑quality construction ensures long‑term sealing performance.
