Air Intake Pipe

Air Intake Pipes and Breather Hoses for Passenger Cars A-Z Car Parts Halifax supplies high-quality replacement Air Intake Pipes (also known as intake boots, ducts, or bellows) designed to restore the sealed airflow path your engine needs. Whether you need a standard rubber hose for a daily driver or a reinforced silicone pipe for a turbo application, we have the correct part for your vehicle.

Function of the Air Intake Pipe The Air Intake Pipe is a flexible tube that connects the air filter housing to the throttle body or turbocharger inlet. Its primary function is to transport clean, filtered air into the engine without allowing any "unmetered" air to enter.

• Sealed System: Ensures all air passing into the engine has been measured by the Mass Air Flow (MAF) sensor for correct fuel injection.

• Flexibility: The concertina (ribbed) design accommodates the natural rocking movement of the engine while the air box remains fixed to the chassis.

• Vacuum & Pressure: Must withstand high engine vacuum (naturally aspirated) or boost pressure (turbocharged) without collapsing or expanding.

Symptoms of a Defective Air Intake Pipe Rubber intake hoses are the most common cause of vacuum leaks. Signs of failure include:

• Rough Idling: Splits in the hose allow extra air in, causing the engine to run "lean" and struggle to idle smoothly.

• Hissing or Whistling: Audible sucking noises coming from the engine bay during acceleration.

• Check Engine Light: Often triggers fault codes P0171 or P0174 (System Too Lean) due to unmetered air bypassing the MAF sensor.

• Engine Stalling: The engine may cut out when coming to a stop or dipping the clutch.

• Poor Acceleration: Reduced throttle response due to air turbulence or loss of boost pressure.

Causes of Failure

• Thermal Aging: Constant exposure to high under-bonnet temperatures causes the rubber to become brittle, hard, and prone to cracking.

• Vibration Fatigue: Engine torque movement flexes the ribbed sections of the pipe, eventually leading to tears in the deep folds.

• Oil Contamination: Oil from crankcase breather systems can pool in the hose, softening the rubber and making it spongy.

• Improper Installation: Over-tightening hose clamps (Jubilee clips) can cut into the rubber, creating leaks.

Replacement Advice

• Inspect Carefully: Squeeze the hose while the engine is off; hairline cracks often only appear when the rubber is flexed.

• Check Clamps: Always replace corroded hose clamps when fitting a new pipe to ensure a hermetic seal.

• Sensor Transfer: Some intake pipes house the MAF sensor or breather connections; ensure these are transferred carefully during replacement.
