Hose Breather Head To Intake (Topran) (M271) (Mercedes-Benz C-Class W203 / W204 / E-Class W211 / W212 / CLK-Class W209 / SLK-Class R171) serves a crucial role in the engine’s crankcase ventilation system. It connects the breather hose to the intake, allowing controlled ventilation of gases from the crankcase back into the engine for combustion. This helps maintain proper pressure within the engine and reduces emissions.
This component is designed specifically for Mercedes-Benz models equipped with the M271 engine, including several key model lines such as the C-Class (W203, W204), E-Class (W211, W212), CLK-Class (W209), and SLK-Class (R171). When replacing, it is important to ensure that the part matches the exact engine type and model references to maintain effective ventilation. Buyers should compare the old breather hose connection, location, and design against this unit.
As part of the cylinder head assembly region, this part interfaces directly with the engine intake system. Look for signs of wear, cracking, or damage on the existing breather head, which can cause rough running or emission issues. Replacement units like this one should be inspected for compatibility with the M271 engine and the specified Mercedes-Benz vehicle ranges.
- Check fit and connection points on the existing breather hose
- Confirm vehicle engine type (M271) and model codes for correct match
- Consider professional assessment if unsure about compatibility
