Hi guys,
just curious on what brand are you guys using for the engine air filter? I been using those generic brand and I just noticed on the filter that I just bought are all fuzzy and all. It is not a clean, smooth groove and my gas mileage isnt that great either. I might have to order from Acura and see if that's help on my mpg or not. Do you guys even use oem brand or don't bother and get generic brand instead? Thanks all.

 

a dirty or clogged air filter wont affect MPG. so, a fuzzy one shouldnt. but thats why you should stick with OEM.

 

I did not know that. I always thought that dirty filter affect the gas mileage lol. I used generic brand on my Accord and never had issue with mpg but this Acura is. Thanks justnspace. I'll order a new one from Acura.

 

A very common misconception; back in the days of carburated engines a dirty air filter would in fact hurt fuel economy, however, with modern fuel injection systems the air to fuel ratio stays constant relative to the amount of air moving through the throttle body.

Said another way, modern engines weigh the intake charge downstream of the filter, and dole fuel out accordingly.

 

So there is no different if I get OEM or generic then? I'm lost lol

 

a generic air filter will be less "finished", by that i mean, it will have "cheaper" materials. for example, it's fuzzy. or the rubber gaskets will be of lesser quality.
but by no means will it affect MPG, or the ability to filter particles.

 

i use aftermarket filters, and I have found that sometimes the rubber gasket doesnt fit into the airbox. a slight modification to the filter allows it to fit nice and snug.

or instead of the filter being 2 inch thick, it's like an inch thick. it still filters and does it's job

 

Got it. This cleared up. Thank you both.

 

Plenty of OEM grade filters to choose from on RockAuto online.

 

I did checked out with rockauto, they seems to be same or slightly less than amazon. I'll just stick to what I got, the beck/arnley for now hehehe. Thanks Sam Axe.

 

Yeah, the misconception of an air filter affecting MPG is still propagated from auto parts stores. Apparently it works, because just about everyone I've spoken to that isn't mechanically inclined always reverts straight to the air filter issue when their MPG's aren't very good. I've probably explained it a hundred times, though I think it's gone in one ear and out the other 90% of the time. The explanation of air/fuel ratio's remaining the same regardless of filter condition seems to cause a brain fart with most people.

 

You can't fix ingrained ignorance
