Air filters
 

I am currently running a k&n in my air box of my Aveo. Would stock filter be better or is there not much difference in how much the car takes in? It will only allow so much anyway... I bought the upgraded filter to get away from buying new ones all the time.I commute pretty far adds up. Just wondering if stock would be better or not.

You won't notice a difference in mileage from switching filters.

Why is that Daox? They rave about there product and then I come to ecomodders and other sites and they say no difference??? Did I waste my 50 bucks 3 years ago? Why no diff? Computer related?

The K&N will allow more air to flow through it. However, the stock filter doesn't become a restriction until you are really trying to pull a ton of air through it (if it does become a restriction at all). In order to pull that much air through the filter you need to have the pedal mashed to the floor and your rpms need to be near redline. If you are in this situation often enough to effect mileage I highly doubt you are worried about your mileage. If you redline through the gears on occasion its not going to kill your mileage drastically. I occasionally have fun in my Paseo and still manage decent mileage I'd say.

Was it a waste of money? Eh, you don't ever have to change the filter, and you don't have to go buy new ones so that is a plus.

Thanks,Just wanted to know if I would be better off stock... At least I don't have to remove the air box lid for a while. K&n will stay

Btw,Why haven't you gotten that great of numbers with the prius? Wifes car? jk

Haha, actually it is. But, its also much harder to beat the EPA rating with hybrid vehicles since they automatically do a lot of what hypermilers do.

Do you have any mods to the prius to help you out? Can you explain the kill switch mod to me? Or a place for me to read it? Does it just take the place of physically turning the key off ?

It seems kind of sneaky and backhanded to me.

The Prius is basically running w/o mods right now. I have done a few things to it, but nothing is currently in the car. A list of my mods are in the garage, but as I said, most aren't on the car right now. Theres no grill block, no phev, the block heater isn't being used, and the EV switch really doesn't help w/o the phev. So, I basically have a new set of LRR tires on it. :)

The kill switch mod is just to make it easier to kill the engine. Most people do it with the key by turning it off and back on (need the car powered up for airbags and some odometers). The kill switch just makes it easier by pressing a button. There are lots of threads on how to do it.
