What this part changes

A direct intake kit replaces the airbox with a short 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 - often the real reason for buying one.

The entire benefit depends 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 what it had just gained. 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 aluminium.

What to plan for

Protect 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 jerking.
Reconnect the crankcase breather hoses left by the original airbox.
