This aFe intake component is the MagnumFORCE Intakes Stage-1 PDS AIS PDS VW Golf/Jetta 00-04.5 l4-1.8/1.9L for 1999-2004 Volkswagen Beetle. Confirm the complete vehicle, engine, filter-media choice, tube or opening size, sensor provisions, emissions status, and included hardware before ordering.
Key Features
- Application-specific airflow path and mounting configuration
- Filter media, sensor provisions, tube size, and emissions classification are model specific
- The 51-10831 draws cooler, denser air from outside the engine bay to maximize combustion efficiency, supported by a heat-shielded housing that keeps intake temperatures down even in stop-and-go conditions.
- This is a direct bolt-on intake requiring no cutting or modification, making it one of the highest-return modifications available for any build.

Will the MagnumFORCE Intakes Stage-1 PDS AIS PDS VW Golf/Jetta 00-04.5 l4-1.8/1.9L fit my 1999-2004 Volkswagen Beetle (aFe 51-10831)?
Match the complete year, make, model, engine, trim, drivetrain, sensor arrangement, and emissions notes shown for this exact product.
Which aFe filter media should I choose?
Dry and oiled media have different airflow and maintenance characteristics. Use only the media supplied or approved for the exact intake and follow its service procedure.
Will this intake require tuning?
Requirements vary by vehicle and intake design. Follow aFe's current application notes and confirm compatibility with any existing calibration or airflow-sensor changes.
Is this intake legal for street use in my state?
Emissions classification is product and application specific. Confirm the current CARB EO or competition-use statement for this exact part before purchase or installation.
Installation Instructions
- Confirm aFe part number 51-10831, the complete vehicle or specification-based application, and all required supporting components.
- Disconnect the battery when sensors or electrical connectors are involved, then compare the new intake path and hardware before removing factory components.
- Transfer sensors and seals carefully, install tubing, couplers, clamps, heat shields, and filter in the specified orientation, and keep every connection clear of heat and moving parts.
- Check for intake leaks, loose clamps, sensor faults, and contact through the full range of engine movement before driving.
