Air Intake Boot
OE Match air cleaner elbow hose for the Porsche 914-4 1.7L, linking the filter housing with the throttle body. Reference 022129967P identifies this replacement intake connector.
Fits
- Porsche 914-4 1.7L
Check fitment for your specific vehicle (model, year, engine) before ordering.
Diagram reference number 1
What This Product Does
The elbow carries intake air between the air cleaner assembly and throttle housing. Its connections need to remain sealed so that air cannot bypass the intended intake path through damaged hose walls or poorly seated joints.
Functions
- Joins the air cleaner outlet to the throttle inlet.
- Provides the elbow-shaped connection within the intake assembly.
- Helps maintain a sealed passage for incoming air.
Technical Details
- Part reference: 022129967P.
- Brand: OE Match.
- Application: Porsche 914-4, 1.7L engine.
Splits, hardened hose walls or connections that no longer seal warrant inspection. An intake leak may accompany an uneven idle, stalling, hesitation or a hissing sound. These symptoms can have other causes, so confirm the leak location before replacing components.
Why Replacement Matters
Renewing a damaged elbow addresses leakage at this connection rather than leaving a deteriorated hose in the intake assembly. During fitting, inspect the adjoining connection surfaces and retaining hardware for damage or poor seating. OE Match focuses on Porsche replacement applications, using original references and application checks to guide component selection.
FAQs
How can a split be identified?
Inspect the hose around bends and connection ends. Gentle flexing may expose cracks; an intake smoke test can help locate leakage.
Do the clamps need changing?
Inspect them during removal. Replace distorted or corroded clamps that cannot secure the joint correctly.
Is the general 914 model listing enough to confirm compatibility?
No. Match the 1.7L application, part reference and engine-number restrictions, and compare the existing intake arrangement before fitting.

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
Technical Details
- Product type: moulded air intake elbow hose
- Location: between the air box and throttle body
- Reference number: 022129967L
- Application: Porsche 914-4 with 1.7L US-specification engine
- 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.

Air Intake Boots – Durable Airflow Connectors for Porsche Engines
Air intake boots are essential components of your Porsche’s intake system, connecting the air filter housing to the throttle body or intake manifold. These flexible connectors ensure that only clean, filtered air reaches the engine, maintaining efficient combustion and smooth performance. A high-quality air intake boot helps prevent unmetered air leaks that can lead to poor drivability, reduced performance, or increased emissions.
At Design911, we stock a comprehensive selection of genuine and high-quality air intake boots for numerous Porsche models like 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each boot is built from durable, heat-resistant materials and designed for an exact fit to provide airtight sealing and long-lasting reliability.
What Do Air Intake Boots Do?
Air intake boots form a critical part of the engine’s air
management system. They:
- Deliver
clean, filtered air from the intake system to the engine.
- Maintain
airtight sealing for accurate air-fuel ratio control.
- Reduce
turbulence to improve engine efficiency and throttle response.
- Protect sensors like the MAF (Mass Air Flow) sensor from contaminants.
Properly functioning intake boots ensure stable idle, consistent power delivery, and efficient fuel combustion — key to maintaining Porsche’s renowned performance and responsiveness.
Why Do Air Intake Boots Fail?
Over time, air intake boots endure constant exposure to
heat, pressure, and engine vibration. Common causes of failure include:
- Cracking
or splitting from heat and age.
- Loose
clamps or fittings leading to air leaks.
- Oil
contamination softening or degrading the rubber.
- Vacuum
leaks causing unmetered air to enter the system.
- Improper installation or wear due to engine movement.
Symptoms of a failing air intake boot include rough idling, check engine light warnings, engine misfires, or loss of acceleration performance.
Why Replace a Damaged Air Intake Boot?
A cracked or leaking intake boot can allow unfiltered air into the engine, upsetting the air-fuel balance and potentially causing long-term engine damage. Replacing the boot restores correct airflow and maintains efficient engine operation.
Benefits of replacement include:
- Restored air-fuel ratio for improved performance.
- Reduced risk of engine misfires and stalling.
- Enhanced throttle response and smooth acceleration.
- Long-term reliability with manufacturer-quality construction.
All air intake boots available from Design911 are made from high-grade rubber or silicone compounds, ensuring superior resistance to heat, oil, and vibration for dependable performance in every driving condition.
