• Designed for naturally aspirated E36-based Z3 platforms

Performance & Design

Airflow Optimization: The intake system replaces the factory air box with smooth, high-flow aluminum intake tubing that reduces turbulence and restriction. Improved airflow supports increased volumetric efficiency across the RPM range.

Throttle Response: Reduced intake restriction allows the engine to respond more quickly to throttle input, resulting in sharper acceleration and improved drivability during both daily driving and spirited use.

Power Gains: Under optimal conditions, gains of up to 10% in horsepower and torque are possible. Actual results may vary depending on vehicle condition, altitude, ambient temperature, and supporting modifications.

Construction & Materials

T304 Aluminum Construction: The intake piping is manufactured from mandrel-bent T304 aluminum, offering excellent corrosion resistance, durability, and improved heat dissipation compared to factory plastic components.

High-Flow Air Filter: The included washable and reusable air filter is engineered to increase airflow while maintaining effective filtration. The open-element design enhances induction sound while remaining refined during normal driving.

Features & Benefits

• Boosts horsepower and torque by up to 10% (conditions dependent)
• Improves throttle response and acceleration
• Mandrel-bent lightweight T304 aluminum intake piping
• Reduces intake restriction versus factory components
• Replaces factory air box and intake tube
• Maximizes airflow through the stock intake manifold
• Produces a deeper, sportier intake sound
• Washable and reusable high-flow air filter
• No ECU tuning required
• Will not void factory vehicle warranty

What’s Included

• Mandrel-bent T304 aluminum intake pipe
• High-flow washable and reusable air filter
• Couplers, clamps, and mounting hardware
• All required installation components

Installation

• Direct bolt-on replacement for factory intake system
• No cutting or drilling required
• Uses factory mounting points where applicable
• Estimated installation time: under 60 minutes
• Basic hand tools required (screwdrivers and socket wrenches)

Installation Note: It is recommended to disconnect the negative battery terminal for at least 60 seconds after installation. This allows the ECU to reset and adapt to the increased airflow. Always install on a completely cool engine.

Filter Maintenance

Inspection Schedule: Inspect the air filter every 5,000 miles and clean if necessary. Driving conditions such as dusty environments, urban traffic, or spirited driving may require more frequent inspection and cleaning.

Cleaning Procedure: Remove the filter from the intake tube and gently tap to remove loose debris. Apply an appropriate air filter cleaning solution to both the inside and outside of the filter element, working it into the filter media. Allow the cleaner to soak for approximately 10 minutes. Rinse thoroughly with low-pressure water from the clean side outward until water runs clear. Shake off excess water and allow the filter to air dry completely in a clean environment. Once fully dry, apply air filter oil evenly according to product specifications and allow the oil to wick through the filter material for approximately 20 minutes before reinstalling. Ensure the filter is completely dry before applying oil.

Sound Characteristics

Intake Sound: Removal of the factory air box combined with the open-element filter produces a deeper, more aggressive intake sound during acceleration while remaining controlled during cruising.
