Detailed Description

The Gates ANTK117 is an engine air intake hose engineered to match OE specifications for the BMW intake system. By replacing a cracked, softened, or leaking hose, it helps restore measured airflow so the engine can run with the correct air-fuel balance. This can support better fuel economy, improved power delivery, and lower emissions when the original hose is no longer sealing properly.

This part cross-references Dorman - OE Solutions 696-060 for the same application. It is a direct-fit intake hose for BMW 323i, BMW M3, and BMW Z3 applications where the hose runs from the MAF to the throttle body.

What It Helps Fix

• Air leaks in the intake tract
• Cracks, splits, or dry rot in the original hose
• Rough idle caused by unmetered air entering the engine
• Reduced throttle response from restricted or leaking airflow
• Check engine concerns related to intake sealing issues

Installation Notes and Tips

Verify the hose routing and port sizes before installation. This part is listed for MAF-to-throttle-body applications on select BMW models, including 1995 BMW 320i, 1996-1999 BMW M3, 1997-1999 BMW Z3, 1997-1998 BMW 328i and 328is, 1998 BMW 323i and 323is, and 1999 BMW 323i. Some 1996 BMW 328i and 328is applications note traction control, and 1999 BMW 323i applications note E36 chassis.

Inspect adjoining clamps, sensors, and mating surfaces for wear before installing the new hose. A clean, properly seated connection helps maintain a secure seal and consistent airflow.
