Performance Air Intake for BMW 3 Series & Z3 1.9L (1996–1999)

BMW’s late-90s 3 Series and Z3 models are celebrated for their balanced chassis, driver-focused engineering, and precise throttle control. Powered by the responsive 1.9L inline engine, these vehicles deliver a classic BMW driving experience. This Performance Air Intake is designed specifically for 1996–1999 BMW 3 Series and Z3 models with the 1.9L engine, enhancing airflow, throttle response, and overall engine efficiency.

By replacing the restrictive factory air box and intake tube, this system allows cooler, denser air to flow more freely into the engine—unlocking noticeable gains in horsepower, torque, and sound without compromising reliability or daily drivability.

Key Features & Performance Benefits

• Boosts horsepower and torque by up to 10%
• Constructed from T304 lightweight aluminum piping
• High-flow air filter engineered for superior filtration and airflow
• Improves throttle response for a sharper, more engaging drive
• Produces a deeper, sportier intake tone under acceleration
• Direct replacement for the factory air filter and intake tube
• Washable and reusable filter – service interval up to 50,000 miles
• Installs in under 60 minutes using basic hand tools
• Designed to not void factory warranty when properly installed

Why Upgrade the Factory Air Box?

The factory BMW intake system is engineered primarily for quiet operation. While effective, it restricts airflow that the engine needs to perform at its best. Upgrading to a performance intake reduces intake restriction, allowing the engine to breathe more efficiently—especially during acceleration.

• Increased horsepower and torque
• Better acceleration and throttle response
• Potential improvement in fuel economy
• Enhanced engine sound with a deeper, throatier tone
• Sportier under-hood appearance
• Lower long-term costs with a reusable, cleanable filter

Vehicle Fitment

• BMW 3 Series: 1996–1999 (1.9L Engine)
• BMW Z3: 1996–1999 (1.9L Engine)

Installation Notes

Installation is straightforward and typically completed in under one hour. The process involves removing the factory air box and installing the intake using common hand tools such as screwdrivers and socket wrenches.

For optimal performance, it is recommended to briefly disconnect the battery after installation so the engine control unit (ECU) can recalibrate for the increased airflow. Always disconnect the battery before performing engine work.

Built for the BMW Driving Experience

This intake system is engineered to complement BMW’s precision engineering, delivering improved airflow while maintaining reliability and drivability. Whether you are enhancing a weekend Z3 roadster or a daily-driven 3 Series, this upgrade brings sharper response and a more engaging engine character.

Upgrade your BMW 3 Series or Z3 today and experience improved airflow, stronger throttle response, and a sportier driving feel every time you get behind the wheel.
