ZeeVert, Yeah it'* a tight fit, good job. I didn't see the air flow arrow that you mentioned, but you know air flow is down through the filter obviously. You can get a push pin retainer rivet at Lowe'* for the location hole on the driver side. The ty-wrap works fine though. The Fram Cabin Air Filters have always been impregnated with charcoal to my knowledge. The oem filters you get from GM are not.

Ooops, I thought I checked all those links.

Here is a picture showing the arrows... PICTURE
I'm pretty sure the air goes the other way.

The air flow arrows appear to be pointing in the wrong direction, I agree.

hate to dig this back up I bought the bocsh and don't have a frame for it. can you do anything with the bosch or do you need the factory frame to use it and does it need anything to start with. my 96 sse died back in october 167000 mile and she blew something and I just got a 2004 SLE 2 weeks ago 43000 lmiles on her.

I think I read that some people have kinda laid it in there, put I can't see that working.

You could check the OEM price, but Parts America is still at $30.

I'd get a Fram w/ frame and save the Bosch for next time (if the frame will work).

It'* works OK Man, My first one was the cheap with fold one, it a little ackward but fits ok. And it got dirty so it did work. Fat half towards the cabin, skinny half towards the motor. It'* not a good a seal as the drop in but It kept debris out for me and by the dirt collected it also filtered. I dont have a pic of my frameless filter to show you, but here is a link to an old thread thats shows Sings Country'* (Tracy) old used frameless filter. You would think that for a $40,000 car, GM would put a cabin filter in the hole......or at the very Least, Tell you it needed one.
