Features
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 potential gains depend on air temperature. A filter installed directly in the engine bay draws in air at 60 °C or more: it is less dense and cancels out the gains it was supposed to provide. Serious 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 aluminum.
What to plan for
- Shield the filter from engine heat: use a heat shield and cold-air intake, otherwise the kit is purely decorative.
- Check the MAF sensor connection: the diameter must match to avoid surging.
- Reconnect the crankcase ventilation hoses left by the original airbox.
