Greybeard can you confirm, did that sticker come with your Trifecta tune?

To be succinct; 91 Octane is recommended for untuned 2.4L. 91 Octane is required for a tuned 2.4L.

Since yours has a sticker stating required, it has been tuned. If you can track down the PO's old posts you might be able to figure out what was done. I tried, but I don't remember how he spelled his screen name.

On the menu bar at the top of any page click on "members" (not hover) then look for the "search members" window (it is a bit hidden).

No I didn't get that sticker... Vince was shooting for 93 octane anyways with mine. I know it's not OEM though.

I don't recall what tune I had read about that came with that or something similar.

i contacted the dealer to ask him to ask the PO because he said he knew him real well. so i just have to wait. i got the owners book out to write down the date and mileage down when we got it and found out that the PO had changed the cabin filter and air filter about 10,000 mile ago. and he wrote down that the air filter was a K&N. how do i take off the cover to get the air filter to just verify that? thanks

The cabin air filter is behind the glove box door above the glove box there is a plastic door to pop open , I have the washable K&N cabin air filter it's nice to be able to wash it out anytime, I feel like it!
The engine air filter , well here's a video

Have you read your Owner Manual? You seem to have a lot of questions that are answered in it.

I found this with "air filter" in the search box http://www.chevyhhr.net/forums/%22ho...ght=air+filter
I'm pretty sure somebody has posted a how-to on the air filter, too. You might want to explore the site, you can't break anything by pushing buttons on your mouse.

Once again, I point to the link in my sig.
Online Owners Manual

After I posted this I made a How-To sticky in the how-to forum. How to replace engine air cleaner/filter

If you have the 2.4 just run 91 and above. They like it better.
