Rated 4.5 out of 5 stars.
Protect your Mercedes' electrical system with this simple but important relay surge protector.
It's a 5-pin unit that replaces OEM numbers 2015400845 and 1265404745.
Basically, it stops voltage spikes from frying your relays or other sensitive electronics.
Common on older Mercedes models.
It's an aftermarket brand, but it does the exact same job.
If you're chasing gremlins or just want to prevent issues, swapping in a fresh surge protector is cheap insurance.
Plug-and-play if you know where it goes.
