Audi B6/B7 S4 (2004–2008) Upgraded Throttle Body Inlet Hose

The Jackal Motorsports Upgraded Throttle Body Inlet Hose is designed specifically for the 2004–2008 Audi B6 and B7 S4 platforms to deliver improved airflow, durability, and reliability under demanding performance conditions. Plus - A MUCH better look than the OEM  piece.

Unlike the factory corrugated inlet hose — which was built for cost efficiency, not performance — this Jackal-exclusive design features a thicker, reinforced construction that resists collapse under high vacuum or heavy load. Each hose is custom-made for Jackal Motorsports, ensuring a perfect fit with the Jackal Performance Intake System while maintaining compatibility with the OEM Air box, throttle body and MAF housing.

Constructed from high-temperature, multi-ply silicone, this inlet hose provides a smooth, unrestricted internal surface to enhance throttle response and airflow consistency. The refined design also eliminates turbulence and airflow separation found in the stock ribbed hose, helping your 4.2L V8 breathe more efficiently — whether you’re running a stock tune or a custom performance calibration.

A clean, gloss-smooth exterior offers an aesthetic upgrade for any S4 engine bay, complementing the Jackal intake and delivering a purposeful, performance-focused look. Each kit includes two stainless steel band clamps for a secure and professional installation.

Why Upgrade

The stock corrugated inlet hose in the Audi S4’s intake system was designed for basic operation — not for the airflow demands of tuned or modified setups. When upgrading your intake, filter, or ECU tune, the OEM hose can restrict airflow and even deform under vacuum.
The Jackal Motorsports Inlet Hose eliminates those weaknesses with a performance-ready construction built to withstand the increased flow and pressure of a high-revving 4.2L V8.
