Heater Core Drain Block Off Plates - F30, F80, F32, F82

Pre-cut plate and rivet hardware to block off the drain hole when deleting the heater core on F30 3-series, F80 M3, F32 4-series, and F82 M4.

Deleting your HVAC system leaves a hole in the trans tunnel where the drain tubes went. This aluminum panel is sized and shaped to block off the hole. In addition to the fire-blocking purpose, the panel also helps to seal out fumes and other gases that can make their way from underneath the car into the cabin.

This panel is riveted to the transmission tunnel for a secure and semi-permanent installation. Rivets are included. Silicone sealant should also be used between firewall and panel to improve the seal.
