What is the main benefit of this larger inlet tube?

The 4.5-inch diameter tube is designed to remove a primary restriction in the intake path. This can help increase throttle response and allow for better airflow to the engine.

Can this inlet tube be upgraded later?

Yes, the S-FLO Carbon Inlet Tube is part of a modular system. You can upgrade to a full AWE S-FLO Carbon Intake System, either open or closed, down the line.

Does this inlet tube fit with aftermarket turbo inlet pipes?

The included coupler fits the factory 3-inch turbo inlet pipe. A separate 4.5-inch to 4-inch coupler is available for aftermarket turbo inlet pipes that are 4 inches in diameter.
