Description
Intake air filter connector for 1.8 and 2.0 16V Citroën and Peugeot vehicles. It is from Peugeot 407 1.8 16V (6FY).
This intake air filter connector (airbox-to-intake coupling) is designed to ensure a sealed, vibration-resistant connection between the air filter housing and the engine intake tract on 1.8 and 2.0 16V Citroën and Peugeot engines. Built to match OEM geometry, the part restores proper airflow routing, helps maintain accurate Mass Air Flow (MAF) sensor readings and prevents unmetered air leaks that can cause rough idle, decreased performance and increased fuel consumption.
Ideal for professional mechanics and knowledgeable DIYers, this connector is commonly fitted on Peugeot 407 1.8 16V (engine code 6FY) and is also used on compatible Citroën/Peugeot applications that share the same intake components. The listing includes the main manufacturer product codes so customers searching by part number can find the exact match quickly.

Installation Recommendations
- Inspect Surroundings: Clean the airbox area and MAF sensor before removing the old connector to avoid contamination.
- Removal: Loosen clamps on both ends, carefully detach any attached vacuum lines or sensors, then remove the old connector without twisting excessively to avoid damaging adjacent components.
- Fitting: Fit the new connector ensuring correct orientation and full seating on mating flanges. Use new stainless clamps if originals are corroded; tighten clamps until snug—avoid over-tightening that could deform the connector.
- Final Checks: Verify all clips and hoses are reconnected, check MAF wiring, then start the engine and listen for air leaks. Clear any related fault codes if present after replacement.
- Tools: Basic hand tools—screwdriver or nut driver for clamps, and a clean cloth for sealing surfaces.
Common Failure Causes
- Aging And Material Degradation: Rubber and plastic connectors harden, crack or split over time from heat cycles and engine bay conditions.
- Vibration And Movement: Repeated engine movement or loose mounting can wear attachment points and cause leaks.
- Oil And Dirt Contamination: Excessive crankcase vapors or spilled fluids can degrade the material and soften seals.
- Improper Previous Installation: Incorrect clamps or twisted fitting may stress the connector and shorten service life.
There is no fixed service interval for this connector. Inspect it during routine air filter replacement or any time the engine exhibits symptoms such as unusual intake noises, unstable idle, loss of power or an illuminated engine warning lamp attributable to air/fuel mixture. Replacing a damaged connector restores correct airflow and helps prevent related drivability faults.
