Good fit.
It worked well for my 2007 Jeep Liberty. It's a good alternative, since Mopar stopped manufacturing these 4-pin relays. Amazon's system says this relay does not fit a 2007 Jeep Liberty, but I knew that wasn't true, so I bought it. Only time will tell how good the quality is. I will update this review if anything happens. In the photo, you can see the old Mopar relay that I replaced.

Good genuine Bosch automotive relay
The Bosch part number of the relays I received is different than what’s advertised, but it has the same specifications and pin out, so it’s all good. It’s obvious that the casing is higher quality than cheap no-name “equivalents”, as are the gold terminals, but I did not disassemble it to examine the innards.

Be careful
Mercedes w164 , that relay's little bigger than original, both will not handle good. But they are working fine, no complaints of it

Great relays. 2006 Scion TC
I originally bought some generic ones but I returned those for the Bosch branded ones, came in Bosch packaging and appear to be high quality. they work great. I have one wired to a momentary push button switch for a starter kill relay.

Its a Bosch Relay
What can I say, it's a Bosch relay. There is one in almost every car made. They have always been a great product.
