Injector extension kit 4 Cyl. - Inlet manifold nozzles + polyamide straws

An Injector extension kit (Inlet manifold nozzles + polyamide straws) is an essential tool for the professional installation of gas systems in vehicles. This specific component ensures that the gas is injected into the exact right position within the engine.

Why is an injector extension used?

• Optimal gas flow and combustion: If the gas nozzles in the inlet manifold are placed too far from the cylinder head, the gas can disperse unevenly across the cylinder within the manifold. The flexible polyamide "straw" extends deep into the manifold and delivers the gas to the exact right spot just before the intake valve. This results in the correct dosage of gas for each cylinder, ensuring smoother engine operation.
• Perfect solution for complex engines: For engines with a complex or compact intake geometry, it is often technically impossible to mount standard gas nozzles close enough to the cylinder head. These extended straws offer the perfect solution for a stable engine idle and run.
• High-quality Polyamide (Rilsan): The straw is made of high-quality polyamide. This material was specifically chosen for its excellent heat resistance, full chemical resistance to LPG and fuels, and high flexibility, which prevents the tube from kinking or blocking the gas flow.

Typical vehicle applications

The use of these polyamide injector extensions is highly recommended and frequently applied to, among others:

• VR6 / V6 engines: Such as the well-known VR6 engines of the Volkswagen Group (VW, Audi), where the intake runners vary in length and shape.
• American V8 engines: In various large American V8 blocks (such as RAM, Chevrolet, or Ford) where space around the inlet manifold is limited or the angle of the intake ports requires a deeper gas injection for optimal idling.
