Air Filter?
 

Since I don't have one yet, what type of air filter does the HHR have stock? Flat rectangular or round cylinder?

I found a close-out on K&N's locally and wanted to see if there was one there that could be easily adapted. Can't beat the $15 price if I could make it work.

I haven't taken it out yet so I'm not sure but if I had to guess I would say square. The GM part number is 22731072 if that helps.

K&N is currently working on a replacement kit that will increase both mileage and performance to a degree. It should be available by the end of the year if not sooner.

I'll post pictures as soon as it's done.

it is a square filter i went to k&n site today and it is square

K&N #33-2339
 

My local parts guy got one for me overnight. Only bad thing is I don't have the HHR yet. I just ordered it Tuesday. Oh well, that gives me more time to buy more goodies. :hhr:

when someone gets one I'd like to know if it actually helps milage or performance noticeably.

I don't have one but I can answer your question. NO! It's just an air filter. :roll: It may help gas milage and add HP but nothing you'll notice. ;)

K&N display
 

Has anyone seen the new K&N displays in the parts houses. Pretty slick.
They have a Lexan box with a place in the top to install a filter. You turn a switch on and a fan pulls air through a Fram filter and exhausts the air out of a round Lexan tube at the rear. You then replace the Fram with a K&N filter, and when you turn it back on the increase in air flow causes a ping pong ball, that has K&N printed on it, to rise to the top of the exhaust tube. Of course with the brand X filter in place you never see the ping pong ball. It seemed like a good reason to go ahead and order my filter and renewal kit. :roll:

Stay away from a oiled filter, unless you like cleaning the MAF all the time. Go with a high quality paper filter.

That is the first time I have heard anyone state that you can have sensor problems by using an oiled filter. I have known quite a few people that have used K&N filters on other applications without any problems. Do you know this from first hand knowledge?

Yes. Also, the MAF is located close to the filter on the HHR, making this a very real possbility.

Yes the oil on the filter makes it's way up the intake tubbing and puts a fine coat on everything including the fine wires on the MAF used to calculate air flow into the engine, plus it gets on the throttle body, etc. I ran one on my Camaro, but the MAF was easy to get to, so every oil change I cleaned it. I've seen many cars come into the dealer with oiled air filters that exhibit drivablity problems due to oil from the filter coating the MAF. Just run a high quality paper filter.

What a bummer. And I thought I was getting a jump on things by buying goodies before my HHR gets here. Oh well, c'est la vie. By the way , I talked to the dealer today. They ordered last Thursday but don't have the confirmation back yet.

INFO FROM K&N FITERS

The last couple of K & N filters that I have bought are none oiling type. I believe most K & N's are that way now. I changed my oil the other day at 15,000 miles and thought I'd throw in a new air filter, but the maintenance manual mentioned changing the air filter at the 50,000 ile oil change. I thought this was really interesting. I didn't really understand the directions for changing the filter to be honest and I'm not completely mechanically challenged. Is it as difficult as it sounds?

No. It is really pretty easy.

1. Unplug the MAF sensor.
2. Loosen the clamp that connects the engine intake to the air box
3. Pull! - The airbox will pop right out of the rubber grommets
4. Loosen the clamp to the fresh air inlet to the air box.

Installation is reverse. Don't forget to re-plug in the MAF sensor. I forgot but noticed as soon as I got on the road. The service engine light was on, and it was shifting really rough.

N&N only makes air filters that you have to oil. Check out their site if you don't believe me http://www.knfilters.com/. There is no such think as a dry K&N filter, every single one they make is a reusable oil type. :roll:

10-4 I wonder why the filter has such a long schedule between replacement?
Thanks, Tex

Chevy is using ALL the current replacement filter elements in the assembly line so they will have enough to continue building HHR's.
They're hoping that by the time you get 50k on your car - they'll be caught up!

Seriously, the element is pretty well shielded and has a long air duct (in passenger fenderwell), this should help extend the filter life somewhat. I live in SoCal, and filters get full of crud from ALL the cars in front of you. I make it a practice to change mine at least every 10k. :)

YMMV :thumb:

That all depends on your actual operating environment. The default air intake setup is really pretty protected. You aren't going to get a lot of "dirty" air coming in the way it is set up. Therefore it should last a long time before it needs to be changed. However, if I still lived in West Texas it would never last 50,000 miles. The entire month of March and most of April there is just one big dustbowl. Remember the pictures of the dustbowl in the roaring 20's from Jr High History Class. It still exists in West Texas every year during that time. Soooo, everyone changes out filters around May EVERY YEAR in that climate.

I stand corrected. I bought a screaming eagle intake for my Harley. It used to be made by K&N. It is now being made by a competitor. The filter rivals K&N's performance, but does not need oiling as the K&N does. You may now pin a pork chop on your ass. :bow:

rotflmao! :beer:

I have been unable to find the K&N air filter at all in the area. Nobody carries it yet! :(

Welcome to the site NY HHR

I was in an O'rileys autoparts and they said they could order it for me said it would take 3 weeks to get though.

Thanks, just found it last night while surfing! :beer:

I've used K&N filters on my last three vehicles and never had a problem with them. My uncle is the service manager at a Chevy dealership and the only thing he commented on was not to "overload" the filter when renewing it. A light coat of the oil was all that was needed. Again, they've worked great for me in the past and I plan on getting one for the HHR when they come out.

CBL

They are out.

Just a head's up; the stock replacement filter is out, but not an entire intake system.

If my local mom & pop parts house can get it in 2 days, here in little ole Owens Cross Roads, Alabama, surely living in NY they can get it as quickly.
I think mine was around $34 or $35.

I've almost alway's used K&N Filters and have been very happy with them. But recently I've been doing research on the various oils, oil filters, and air filters, from independant labs and was shocked at what they're saying. Although the K&N rates very good (especially over paper) the foam type (like ITG) actually out perform the K&N (and other gauze type both oil and oiless) filters in both air flow and filtering.

Both Mobile one oil and oil filters are in the top three, so I'll stick with M1.

That's why we are going with AEM. Their oiless paper filters can flow twice the required airflow for each application without pressure dropping. This means the element will always provide more than adequate flow for your engine - even after you start modifying it. They also filter down to 1 micron (99.4% efficiency), and cleaning them is very simple.

Of course, no oiling is a big plus too! :thumb:

I can't wait till we can get one. Im pretty sure this was asked before but is aem doing it for both engines?

It will work on both models. I am going down to AEM next week to get the "first article" test fitted. It has already been test fit on the 5-speed and is nearing final production status.

More details when they are available...

is there a cold air intake in the make?

I order me a k&n filter for my new 2006 hhr, Will be getting on the 31st by fedx.
