Went to Advance auto to get one today and none on the shelf and no longer a tag for them.

 

I work for a Chevy dealer and I don't think they are discontinuing it. If you can't find a PF35 look for a PF1218. It's the same as a 35 but it has an anti-drainback valve in it so it can be mounted sideways. I've used it for 3 years now and haven't had a problem.

 

They just changed the number. I think it is the PF1218, at least that is what the Wix filter cross reference indicates.
