Description

This is a used air intake resonator designed for the 1.4 VTI and 1.6 VTI petrol engines fitted to selected Peugeot and Citroën models. The resonator reduces intake noise, smooths airflow into the throttle body and contributes to stable engine response at low and mid-range rpm. Supplied with original mounting points, this part is a direct replacement for vehicles using the corresponding OEM part numbers and is suitable for professional fitters and DIY mechanics who require a cost-effective repair solution.

Fitment And Function

• Function: Dampens intake tract pulsations and reduces cabin intake noise while helping to stabilise airflow toward the throttle body and mass air flow sensor.
• Engine Fitment: 1.4 VTI and 1.6 VTI petrol engines.
• Typical Symptoms Of Failure: Increased intake noise or whistling, rough idle, reduced low-end smoothness and, in some cases, degraded engine response if vacuum leaks affect sensor readings.

Replacement Procedure

Replacement is straightforward for a competent mechanic. General steps:

1. Allow Engine To Cool And Work In A Clean Area.
2. Remove Any Engine Covers Blocking Access To The Air Intake Tract.
3. Loosen Hose Clamps And Remove Intake Hoses Connected To The Resonator.
4. Unclip Or Unscrew The Resonator From Its Mounting Points, Taking Care Not To Damage Nearby Sensors Or Wiring.
5. Compare Old And New Parts For Correct Orientation And Fitment. Replace Any Damaged Seals Or Hoses.
6. Install The New Resonator, Reattach Hoses And Clamps, Ensure Secure Mounting And Proper Seal At All Connections.
7. Start The Engine And Inspect For Air Leaks, Abnormal Noises And Stable Idle.

Installation Recommendations

• Inspect Associated Hoses, Clamps And The Air Filter Housing When Replacing The Resonator; Replace Perished Hoses Or Worn Clamps.
• Clean Mating Surfaces And Ensure The Mass Air Flow Sensor Is Clean And Properly Seated—contaminated or loose connections can mimic resonator faults.
• Use New Hose Clamps Where Possible And Tighten Evenly To Avoid Distortion. Follow Manufacturer Procedures For Accessory Removal.
• After Installation, Check For Vacuum Leaks And Confirm Engine Runs Smoothly Across The Rev Range.

Why The Part Fails Most Often

• Material Degradation: Plastic Resonators And Rubber Connectors Harden And Crack Over Time Due To Heat Cycles And Oil Vapor Exposure.
• Mechanical Damage: Road Debris Or Impact Can Crack The Resonator Body Or Break Mounting Tabs.
• Loose Or Broken Hoses/Clamps: Poor Sealing Leads To Vacuum Leaks And Increased Intake Noise.
• Age-Related Leaks: Seals And Joints Lose Elasticity Resulting In Reduced Effectiveness.
