hey guys i was thinking about installing air filters to increase mpg because i find myself at the gas station a lot =x.

what you guys think?

your driving style is the only thing that will save you money at the gas pump.

K&N might give you a percent or two improvement but being gentle on the throttle/brakes, timing lights, etc, etc can give you significant savings.

kevinwithdabenz

yeah i guess. i just been doing a lot of driving though lately, so anything that might help would be helpful right? or maybe im just looking for an excuse to have another mod on my car =x

plus theres the myth about added horses =x lol thanks for the quick input though guys !

I can't imagine it will make a significant difference at the pump.

Blazeitup123

the money you spend on the filters will take ages to get back in gas savings. and who knows if they even improve mileage. i'm sure someone will come along and say they do, right after someone says they don't.

i have noticed with these k&n things is that there are just as much negative reviews as there are positive.

that is why i am staying away.

Thy didn't work out for me, I had some hesitation while they were installed. Ended up switching to Green filters. BMC's are good also

kevinwithdabenz

why green ? and yea i heard of bmc too ont too much on them though

Blazeitup123

Formula 1 apparently uses BMC. So i'm sold. Spensive tho.

kevinwithdabenz

yeah i know that azn has them, but idk where to buy them .

Do not use any oil impregnated filters - they WILL foul o2 sensors etc sooner or later.

Tire pressure, drive style is everything re mpg

You could get the part # on here http://www.bmcairfilter.com/and probably search that through Amazon. I have these for the E55 airbox I'm about to install..

dynomite05

That only happens when people re-oil them with too much oil. If you do it the correct way you should be fine. The BMC's are washable so you should be able use over.

BMC filters

thats for the 350 motor. we share the same airbox so we can both use these. PN: 262/01

What are the pro and cons of K&N filter? Any link to the reviews?

thanks

If not very carefully oiled K&N filters mess with the MAF & O2 sensors.

Spec_Davis

I have K&N and they work great

denot

Great as in?

Spec_Davis

MPG save some gas during long trips

denot

Ooo... not really worth it then. No performance benefit at all?

Spec_Davis

a little but you can not notice it at all but it will save you some MPG.

K&N work good for me

I have also heard that the oil will cause sensors to go bad over time, What happen if you just dont oil the filters at all?? I have found out that paper air filter like ours are the best type of filtration, might not be the best air flow but definitely best filter. I thnk I rather have a clean engine than save 1-2mpg.

K&N's on M-B's are usually known to do more harm than good.

Any "gain's" are usually negligible, if they even exist.

M-B's stock filters are known to be about as good as it gets for the particular motors. I'd use that money on something else.

BTW, tire PSI, clean injectors, clean/serviced air filter, driving style, etc. will affect MPG's a lot more usually.
