This Crankcase Ventilation (PCV) Breather Hose is a critical emissions control component designed for the Mercedes-Benz M102 engine series. It facilitates the safe transfer of blow-by gases from the crankcase back into the air intake system. By maintaining a sealed environment for these vapors, the hose ensures your classic engine runs smoothly while preventing environmental contamination and internal pressure imbalances.

Dual-Diameter Configuration: Features precision-engineered internal diameters of 16.5mm and 12.8mm to ensure a secure, airtight fit across different connection points.
Engineered Dimensions: With a total length of 100mm and external diameters ranging from 20mm to 24mm, this hose follows the original equipment geometry for a perfect fit.
Oil-Resistant Material: Fabricated from high-grade synthetic rubber specifically formulated to resist the corrosive effects of oil vapors and fuel mist.
Thermal Stability: Designed to endure the intense heat of the engine compartment without hardening, cracking, or collapsing over time.

Optimized Engine Performance: Replacing a brittle or leaking breather hose restores vacuum pressure, which stabilizes idling and improves overall fuel efficiency.
Prevents Oil Leaks: By maintaining proper ventilation, this hose helps prevent excessive pressure buildup that often forces oil past sensitive engine seals and gaskets.
Seamless Installation: As a direct-fit replacement for OE 1020941987, it eliminates the need for universal hoses or modifications, making it ideal for both professional mechanics and restoration enthusiasts.
