Intake Tube Kit / Direct Intake Kit for BMW 2 Series, 3 Series, 4 Series with N20 engine code
Specifications
What this part changes
A direct intake kit replaces the airbox with a short intake pipe and a cone filter. Two things change: airflow, because the airbox restrictions are removed, and intake noise, which becomes clear and very noticeable under load - this is often the real reason for buying one.
All the actual gains depend on air temperature. A filter placed directly in the engine bay draws in air at 60 °C or more: it is less dense and gives back what the kit initially gained. Proper kits come with a heat shield and a cold-air intake; without one or the other, the gain is theoretical. Carbon conducts significantly less heat than aluminium.
What to plan for
- Shield the filter from engine heat: use a heat shield and cold-air intake, otherwise the kit is merely decorative.
- Check the MAF sensor connection: the diameter must match to avoid hesitation.
- Reconnect the crankcase ventilation hoses left by the original airbox.
