BMW E46 trunk firewall

BMW E46 trunk firewall is a fire separation panel for separating the trunk from the cabin. It is especially relevant for race cars, drift cars, trackday cars and modified cars where a fuel cell, fuel tank, battery, fuel pumps or other technical components are installed in the trunk.

A trunk firewall helps create a safer barrier between the driver and the trunk. In the event of a leak, fire or technical fault, the fire separation panel can help limit flames, heat, smoke and fuel vapours from entering the cabin. This makes it an important safety part on a BMW E46 used for motorsport or hard driving.

This version is made from 1 millimetre aluminium, providing low weight and good strength. With a weight of only approx. 1.3 kg, it is suitable for performance and motorsport cars where weight saving is important. It is designed for BMW E46 coupe.

The fire separation panel is mounted between the rear seat area and the trunk, creating a more closed separation between the cabin and the rear section. It is especially suitable for cars where the rear seats have been removed and where a more correct motorsport-style build is desired.

Note: Installation must be carried out properly so the panel seals tightly against the bodywork. For motorsport use, the installation should always be checked against the applicable regulations for the class or series in which the car will be used.
