Why This Part Fails Most Often
Intake Hoses And Necks Are Exposed To Engine Bay Heat, Vibration And Occasional Oil Vapors, Which Over Time Cause Material Fatigue, Cracking Or Hardening. Common Failure Modes Include Small Cracks At Bends Or Attachment Points, Clamp Loosening, And Deformation From Prolonged Heat Cycles. Contaminants From The Breather System Or Accidental Impact During Maintenance Can Accelerate Deterioration. Regular Visual Inspection During Service Intervals Helps Detect Early Signs Of Wear.
Purchasing Tip: Customers Frequently Search By The OE Numbers 9641464480 And 143421. Including These Codes In Your Search Will Speed Up Finding The Correct Intake Neck For The 1.4 HDi 66 kW Applications.
