Does the brand matter?

Any comments on Walker vs Denso vs Bosch sensors

 

Nope. I just got the UNIVERSAL one from Walker and it was working fine before the accident. Bosch is what comes on our cars from the factory.

 

Brand doesn't really matter as Big D said... I would recommend getting one with the OEM connector - that way you don't have to worry about trying to splice in your old connector to the the sensor harness.... (not hard to do, just adds one more point of failure in the future).
