Specs At A Glance

Good To Know

Q: Do I need to replace clamps when installing this hose? A: Reusing the original clamps is often possible, but new clamps are a good idea if the old ones are corroded or stretched.

Q: Can a bad breather hose cause a check engine light? A: Yes, a leaking PCV vent hose can introduce unmetered air and trigger lean-fuel codes, so scan for faults before and after the repair.

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