Royal Enfield Continental GT 535 Euro 3 Air Filter Box Outlet Pipe – 573140/A

Restore the intake connection between the air-filter box and throttle-body side of the original Royal Enfield Continental GT 535 Euro 3 intake system with this genuine air-filter pipe outlet. Exact part number: 573140/A.

The factory parts catalogue identifies this component as NR61 Air Filter Pipe Outlet. It is the shaped intake connector fitted at the clean-air outlet of the Continental GT 535 airbox. A cracked, hardened, loose or incorrectly sealed outlet pipe can allow an intake leak and may let unfiltered air enter downstream of the air-filter element.

Important: This is the air-filter box outlet pipe. It is not the air-filter element, airbox inlet cover, drain hose, breather hose, complete airbox, throttle body or intake manifold.

Confirmed Product Details

Confirmed Compatibility

Registration year alone is not enough to confirm this intake part because market specification, emission version and previous airbox or throttle-body modifications can change the required connector. Confirm 573140/A, the original pipe shape, both end diameters and clamp position before opening the package.

Do Not Order For

• Royal Enfield Continental GT 650
• Royal Enfield Interceptor 650 or any other 650 Twin model
• Royal Enfield Classic, Bullet or Electra 350/500 unless an independent model-specific catalogue confirms 573140/A
• Himalayan, Scram, Guerrilla, Meteor, Hunter or current J-Series motorcycles
• Motorcycles converted to a different carburettor, pod filter, custom airbox or modified throttle body without physical verification
• Any intake requiring a different pipe shape, diameter, angle or mounting arrangement

The term “535” or “UCE” by itself does not confirm fitment. This listing is specifically for the Continental GT 535 Euro 3 NR61 air-filter box application.

What the Air-Filter Outlet Pipe Does

Air first passes through the filter element inside the airbox. The outlet pipe then carries that filtered air from the clean side of the airbox toward the engine's throttle-body and intake system. The pipe also allows a small amount of controlled movement between the airbox and engine-side intake components while maintaining a sealed connection.

If the pipe splits, becomes loose or no longer seals at either end, the engine may draw air that has not passed correctly through the filter element. This can disturb the intended intake path and expose the engine to dust or debris.

What You Will Receive

1 × Genuine Royal Enfield NR61 air-filter pipe outlet – 573140/A

The clamp, air-filter element, airbox seal, inlet cover, drain pipe, drain clip, complete airbox, throttle body and installation labour are not included. Order those components separately if inspection shows they are also required.

When Should the Outlet Pipe Be Replaced?

• Visible cracks, splits or tears in the pipe body or ends
• Rubber has hardened and no longer conforms to the mating connection
• An end is stretched, swollen, distorted or no longer retained securely
• Dust tracks or contamination appear downstream of the air filter
• The connection repeatedly loosens despite using the correct undamaged clamp
• The pipe was damaged during airbox, throttle-body or engine work
• The original part is missing after a modified intake is returned to standard

Diagnostic Note

Do not replace the pipe solely because the engine runs poorly. First inspect the air-filter element, airbox cover and seal, outlet pipe, retaining clamp, throttle-body connection, injector system, intake manifold and vacuum-related connections. A blocked filter, loose clamp, damaged seal, fuel-system problem or another intake leak can produce similar symptoms.

Remove the filter element and inspect the clean side of the airbox for dust. Contamination beyond the filter indicates that the full sealing path should be checked before the motorcycle is used further.

Installation Notes

• Work with the motorcycle secure, ignition switched off and engine cool.
• Remove the surrounding panels and airbox components only according to the applicable workshop procedure.
• Prevent loose dirt, fasteners or cleaning material from entering the throttle body or intake tract.
• Compare the new 573140/A pipe with the removed part before installation.
• Inspect both mating necks and the separate 573141/B clamp for damage, corrosion or distortion.
• Clean the sealing surfaces without using chemicals that can damage the pipe.
• Seat the pipe fully and align its moulded shape without twisting, stretching or kinking it.
• Position the correct clamp in the factory location and tighten only to the applicable specification.
• Do not use household adhesive, excessive sealant, wire or an incorrect clamp to compensate for damaged components.
• Confirm that the throttle operates freely and that no hose, cable or wiring is trapped after reassembly.
• Start the engine and inspect the complete intake connection before road use.

Important Return-Prevention Check

Before opening the package, confirm all of the following:

• The required item is the air-filter box outlet pipe, not the filter element or drain pipe
• The exact required part number is 573140/A
• The motorcycle is a Continental GT 535 with the applicable Euro 3 NR61 airbox
• The existing intake has not been converted to a pod filter, different carburettor or custom airbox
• The old and new pipe shape, length, angles and both connection diameters match
• The fault is not caused only by clamp 573141/B, the airbox, throttle body or another intake component

We do not offer exchanges. A correctly supplied item is not returnable or refundable after delivery, opening, installation, testing or use. Wrong model selection, confusing this outlet pipe with a drain or breather hose, or ordering for a modified intake does not make the supplied part incorrect. Record a complete unboxing video and report a wrong, missing or transit-damaged item within 24 hours with the required proof.

Frequently Asked Questions

What is Royal Enfield part 573140/A?

It is the NR61 air-filter pipe outlet fitted at the clean-air exit of the applicable Continental GT 535 airbox.

Which motorcycle is confirmed for 573140/A?

The confirmed parts-book application is the Royal Enfield Continental GT 535 Euro 3 with the original NR61 air-filter box assembly.

Does it fit the Continental GT 650?

No. The GT 650 uses a completely different twin-cylinder intake and airbox system.

Is this the air-filter element?

No. The replaceable GT 535 filter element is a different part, referenced as 573139/B.

Is the retaining clamp included?

No. Clamp 573141/B is separately catalogued and is not included with this outlet pipe.

Is this the airbox drain hose?

No. Drain pipe 573142/B and its clip 573143/B are separate smaller components.

Does the outlet pipe connect the airbox to the throttle-body side?

Yes. It forms the clean-air connection leaving the airbox and leading toward the original engine-side intake system.

Will it fit a carburettor-converted GT 535?

Not automatically. Carburettor type, adaptor diameter and airbox position can differ. This listing guarantees the original 573140/A application, not universal conversion fitment.

Can a cracked pipe affect engine running?

Yes. A leak downstream of the filter can disturb the intended intake-air path. However, poor running can also have filter, fuel, ignition or other intake causes, so diagnose before ordering.

Should the clamp be replaced at the same time?

Replace it if it is stretched, corroded, distorted or cannot secure the pipe correctly. A new pipe cannot compensate for a damaged clamp or mating neck.

Can sealant be used instead of replacing a split pipe?

No improvised repair is recommended for an intake component. Replace damaged parts and restore the factory-style connection.
