Intake manifold Jinling 250 JLA-21B ATV 300 JLA 931E Quad

Intake Manifold – For Jinling Racing ATV 250 JLA-21B & 300 JLA-931E 

Rubber Connection Piece Between Carburetor and Cylinder Head

This Intake Manifold (Intake Boot) is an essential spare part for the correct fuel mixture delivery to the engine. It was specifically developed for the sporty Jinling Racing ATV models, including the Jinling 250 JLA-21B and the Jinling 300 JLA-931E.

The intake manifold connects the carburetor to the cylinder head in an airtight manner. As this component is usually made of rubber or rubber-metal compounds, it is susceptible to embrittlement, cracking, and leaks due to heat and aging. A leaky intake manifold causes the engine to draw false air, resulting in a lean mixture, poor throttle response, overheating, and in the worst case, severe engine damage. Replacing this part is critical for flawless engine performance and reliability.

Top Features and Benefits:

• Sealing: Restores the airtight connection between the carburetor and the engine.

• Precise Mixture Delivery: Prevents the intake of false air and protects the engine.

• Exact Fitment: Directly compatible with the mentioned Jinling Racing ATV models.

• Performance Restoration: Solves issues such as poor throttle response and rough idling.

Important Installation Note:

• Seals: Ensure that all sealing surfaces are clean and use new gaskets if necessary (if not included in the scope of delivery).

• Tightness: Tighten the clamps and screws evenly and firmly to ensure optimal sealing without damaging the material.

• Check: After installation, the tightness of the intake manifold should be checked with the engine running (e.g., using brake cleaner).

Secure the correct fuel mixture preparation and the performance of your Jinling Racing ATV!
