I went to change mine ina 2003 GMC Envoy. it had the port for the filter but no filters were in there. When I went to put the filters in I had a problem sliding the second filter up. The filters had a thin layer of foam around them, I had to remove the foam on the side between the two filters. It worked , I suppose you could just put some smooth tape over the foam.
Can you tell me what year and model it has left so I can order them and put some on it since I have a 2002 GMC envoy and it doesn't have it and I want to know what other GMC it has left because it gets a lot of dust without them I would greatly appreciate it
I went to auto zone and the guy couldn't find the airfilter and he ended up going thru all the trims and couldn't find an airfilter. Thanks I'll ask for a GMC Sierra
