Has anyone tried replacing the stock air filter with a K&N in the stock turtle shell air handler?

 

I did. Made no difference. I replaced the whole setup with Airaide intake and filter. Made alot of difference.

 

I did also. I wasn't looking for a performance increase though. I already had filter cleaner and oil, so I got a K&N filter. It should save you money in the long run, since K&N filters are supposed to last 100,000 miles.

 

I changed stock filter with K&N. Found no difference.
Changed to K&N Intake, and observed mileage increase and better sound.

 

that got me thinking so i got my manual and started looking for turtle shell air handler........then i realized..."blonde moment" LOL!!!!


i have a kn air filter in the stock box....but hopfully after paying off some bills with income...that will change...

 

I have a K&N in the stock air box of a 2.4 auto. Is there a second part to this question?

 

Do you like it or not?
Does it work any better than the stock air cleaner?
More power?
Better mileage?
Is it cost affective?

 

I like K&N filters. I've put them on the last three cars I've owned.

It works pretty much the same.

Nothing you'll notice. Maybe like 1 or 2 hp max if that.

At first I seemed to be getting 1 or 2 MPG more. After driving with it for a while it seems like I'm getting 1 or 2 MPG less.

If you plan in keeping your HHR for a while and look at the cost of multiple disposable replacement filters versus a the initial cost of a K&N, the number of times you'll need to charge it, and the cost of recharge kits then yes.

 

Isn't the stock filter good for like, 50,000 miles anyway? You figure $14 bucks a pop for every 50k comes out way less in the long run than a $45 K&N once plus recharging every 50k?

 

You are supposed to recharge at 100K in normal daily street driving conditions. I only paid like $30 for the K&N replacement and it comes with its first oiling from the factory. My stock filter was dirty as hell by 30,000. That's about when I switched to a K&N. The way I look at it the K&N pays for itself within your first 100K or so.
