Specs At A Glance

Good To Know

Q: Does this line come with clamps? A: This listing covers the breather intake line itself; reuse your original clamps or fit new ones if the old hardware is worn. Check your specific engine bay routing before installation.

Q: Can a bad breather line cause a check engine light? A: Yes, a leaking or disconnected crankcase breather hose can lead to unmetered air entering the system and trigger lean or misfire codes. Replacing the failed line often clears the related symptom once codes are reset.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
