Frequently Asked Questions About the ID1750-XDS Audi/VW 1.8t

What does the final '.4' in the 1750.60.14.14B.4 part number signify for this kit?

The final '.4' signifies that this is a complete set of four injectors. This kit is sized specifically for the four-cylinder Audi/VW 1.8T engine, ensuring you receive a flow-matched set for even fueling.

Will the 60mm body ID1750-XDS fit into the factory fuel rail of a typical Audi/VW 1.8T engine?

The 60mm body is generally the correct length, but this kit is typically designed for use with aftermarket fuel rails common in 1.8T big-turbo setups. Using the specific 14.14B seals ensures a precise, leak-free fit.

What is the key tuning benefit for the Audi/VW 1.8T platform using the ID1750-XDS?

The key benefit is the injector's exceptional short pulse width linearity. This allows tuners to achieve a stable, low-RPM idle and reliable cruise control, which is essential when running such a large 1750cc injector on the small 1.8L engine.

Is upgrading the fuel pressure regulator (FPR) necessary when installing 1750cc injectors on a 1.8T?

Yes, mandatory. The high flow rate requires an adjustable, high-flow fuel pressure regulator (FPR). This is necessary to maintain consistent pressure and handle the significant fuel return volume under high boost.

Are the seals included with this injector compatible with both gasoline and high-ethanol E85 fuel?

Yes. The seals provided in this kit are made from materials (such as Viton) that are fully compatible with both standard pump gasoline and high-concentration E85 ethanol fuel, ensuring a durable seal regardless of fuel type.
