Rep Power: 368

well I was going to write something about this a few days ago but forgot..

anyhow after 1 and a half tank of gas, (about 600+ miles) later... I'm happy with my drop in filter.

it has increased my average mpg of 30 mpg to 35 mpg.

I do mostly city and highway driving... and although most of the time I shift at the appropriate point... I do occasionally redline or downshift into high rpm ranges for accleration.

so 5+ mpg is pretty awesome! I did 400 miles and I still have about 2 gallons left.

it should pay itself off pretty soon. so far in that tank of gas, I save a buck or two... pretty soon it'll even out... and not to mention when the time I'm suppose to get a new filter.. I can keep using the K&N.

so buy it NOW NOW NOW.

heh.

um... 36 shipped at http://www.martelbros.com/cgi-bin/st...ore=direct.KNN

or was it 38? something like that.

More oxygen into the engine equals better MPG? [IMG]i/expressions/face-icon-small-confused.gif[/IMG]

More O2 results in more fuel being burned to prevent running lean, but results in more power.

With my paper filter and deleted resonator I get 48mpg highway.

I see an improvement in my mpg as well. Although I get only about 25mpg on average now. I used to get about 22mpg. I drive hard though.

geez you drive hard grey.

yeah, this is a high flow air filter.. so I suppose its weird that while its suppose to put out more power and use up more fuel.. (which I dont really think it does.. or make any significant difference).....

but the mpg dont lie. heh. I remember there's quite a few explaination on it... but the only thing I can think of now is a more efficiently flowed intake... thats all.

Hi all,

With K&N drop-in, the air sucking sound is much better than before. I also can see the MPG improved as well as performance. The better airflow will require less engine power to intake the air. So, less_load = more_power + better_MPG. Not bad for $37+/- investment.

Yeah, I also notice an improved sucking sound. Especially when turning the car off. It sort of sounds like an AEM CAI now. You know, that weird turbo BOV sound the intake makes. I now hear that.

I think to understand the increase in mpg you have to think of it this way. You basically increase the horsepower without increasing fuel consumption since you're not adding any more fuel. You're just removing the restrictive stock air filter and replacing it with a high flowing K&N. With the gain in horsepower you don't need to step on the gas as much as you did before to get the acceleration that you were getting. So in effect it's you that's increasing the mpg, not the car. That's how I see it working anyway...

I don't know about performance increases for this filter since I don't have on my car. Imo, the fact that it will last the life of the car is more than adequate justification for purchase. Even if you don't care about performance, we all care about our money.

Cap: I can't possibly fathom how you got 5mpg increase from that filter. A tank in a half isn't a big enough sample to draw that conclusion. Plus, I am sure the cooler weather is playing a factor. Not sure how much you use your ac. 5mpg is just hard for me to swallow. Heck, that would be a miracle.

My mileage went up when I went to PA, cause the weather is cooler, (colder air to engine), and I didn't have to run the AC as much. If you really want to compare filters for mileage, you just about have to run a couple tank fulls on each, on the same roads, same weather conditions. Eliminate as many variables as possible.
