Air intake elbow hose. Porsche 914-4 1.7L US Spec  ❭  022129967L

Air intake elbow hose by OE Match for the Porsche 914-4 1.7L US Spec. This moulded intake component connects the air box to the throttle body and replaces an ageing, cracked or poorly sealing hose.

Fits

• Porsche 914-4 1.7L US Spec

What This Product Does

The elbow carries filtered intake air between the air cleaner assembly and throttle body. An intact hose helps maintain a sealed intake path, reducing the risk of unmetered air entering the engine and disturbing the air–fuel mixture.

Functions

• Connects the air box to the throttle body
• Provides a sealed path for filtered intake air
• Accommodates the angled routing between intake components
• Helps prevent air leaks within the intake tract
• Supports consistent idle and throttle operation

Symptoms of Fault

• Visible cracking or splitting when the hose is flexed
• Rough, hunting or unstable idle
• Hissing or whistling from the intake system
• Hesitation during acceleration
• Stalling or difficult low-speed running
• Lean mixture or intermittent misfire symptoms
• Loose clamps or poor sealing at the connections

Why Replacement Matters

Repeated heat cycles, vibration and age can harden the original hose or open cracks around its bends and connection points. Replacing a leaking elbow restores the sealed passage between the air box and throttle body. Inspect the adjoining clamps and fittings during installation, as distorted or corroded hardware may prevent the new hose from sealing correctly.

FAQs

• How can a damaged intake elbow be identified?
  Inspect the hose while gently flexing it, paying particular attention to the folds, bends and clamping surfaces. A smoke test can reveal leaks that are difficult to see.
• Can a split hose cause poor running?
  Yes. Air entering through a crack may upset the intended air–fuel mixture, particularly at idle and low engine load.
• Should the clamps also be replaced?
  Renew clamps that are corroded, distorted or unable to apply even pressure around the hose connections.
