Air Filter / MPG improvments ?
 

Anyone have a favorite brand of a air filter for their HHR ?
also besides proper psi in your tires , and regular oil changes etc.
any good idea's for getting the best fuel mileage . with gas prices inching near $3 near me.

The best advice is to ease off on the gas pedal a bit. No hard accelerations, whenever possible run at 60 instead of 65, 65 instead of 70, etc.

I agree with Doc brown. Easy does it on the gas pedal always works for better mileage. Seems gas here in So Cal is always $3.00 or more. I do use a K&N air filter and keep the tires inflated to what the sticker says on the door jamb. Have a 2.4 and it seems to run a bit better on premium.

i had a k&n on my previous car, but i had a short/ram air intake on that car.
this car im keeping with the faactory air box for now ..
is the $48 k&n factory shape filter worth the money , since its last the lifetime of the car and washable, instead of spending $12-20 eery 6-12 month's on a filter i guess it pays off in 2-3 years.
crazy that gas prices that much higher in cali here it fllex's from 2.63 - 2.83 back and forth..
and all 4 tires are usually around 34psi, right?

Regular air filters should last a few years and quite a few thousand miles unless you live in very dirty/dusty conditions.

ive been replacing mine every 12 month's, i did it last summer
and opened it up today and in the hose and the box there was leaves and so much dirt in there, so i cleaned it out well..

If you are gonna hang onto it for a while the K&N makes sense in savings..

I'm running one in my stock 2.4 box..

Also running 2.4 stock w/ K&N filter.

Just changed my air filter today for the first time, bought the car used with 19K miles last March........ 22K on it now. I seriously think I just pulled the original factory filter out of there...... what a mess it was. :eek:

I used a Purolator because I didn't have a preference and that's what the parts guy handed me.......

I've been getting great mileage, wonder how much it will go up now that it can breath. :cool:


EDIT: Just went for a test drive with the new purolator..... huge difference in performance.... :steering:

We used to have a 1/2 ton 4WD GMC Pickup with a 350. From day one, it was slow and it got around 16MPG. People I knew told me they put in a K&N and gained all sorts of mileage. I bought a K&N, it was slow and it got 16MPG. Then, these people told me to get a Flowmaster, and it would make a huge difference, so I did. The truck was now loud, slow, and got 16MPG. I was then told that the cat was the problem and if I removed that, it would make a world of difference. Now the truck was really loud, slow, and got 16MPG. What I found was that the people who made these claims never actually checked their mileage.

19 years later, I still have that K&N. It's on it's 3rd truck now. If you're looking for MPG, save your money. If you never want to buy another air filter for your HHR, buy a K&N.
