I have a 2005 Outlander XLS, I was told that installing a K&N air filter would improvement the fuel MPG along with HP.
I'm not really concerned about extra power etc. but would sure like to increase MPG.
Any thoughts.

Brian,
I'm picking up a K&N air filter for my 2004 XLS Outlander today. I too am looking for more MPG. I'll let you know how it works.

 

I went on the K&N site, and couldn't find a filter for my 2008 outie. Do they evenmake them for 07/08 model year or not yet?

 

I've used a K&N on my previous 3 cars and I've never noticed a difference..

 

Just because you can't feel 5 extra hp, doesn't mean it isn't there. Believe me your a/f ratio will look a little different after the filter install.

 

I was thinking more in the MPG department..but it's never been much of a noticeable change in the power area either on my last 3 vehicles.The biggest advantage would possibly be in savings in air filter replacements if you plan on keeping it for a long time...but then there are people that say it lets in more dirt incrasing wear on the engine.

I'm not anti-K&N..I have one on my bike along with a hi flow setup and it made a huge difference..I've just not noticed the same with their drop in filters in cars...which lets me believe that the real bottlenecks aren't with filter.


Just went to K&N's site..and they no longer claim that their filters will give you better fuel economy over other types of filters..they only say that replacing a dirty filter can increase mileage...I'm guessing they got in some trouble over the claim
