Has anyone tried the air filter upgrade on their Pat? If so, what results did you have? Worth the cost?

I installed just the K&N filter, and after several miles of driving, I averaged one extra mpg. Noise stayed the same and it seems like it responds a little better too.

It's a small improvement from the stock one, and it's reusable/washable. If you have that extra to spend, I think it's worth it.

It's a downgrade,sure it flows better but filters worse and the PCM and mechanical insides of the engine will only accept so much air coming in.You'd need to mod the engine internals and have the PCM re-programmed to take any effect it may give.

Thanks for the insight. K&N claims better mpg and 6.3 additional hp, which sounds good (more power AND better mileage?!), but I don't want to be playing around with computers and such...definitely not my forte.

You may till the PCM learns around it and adjusts back to stock in a few drive cycles.Hence why PCM tuning is required.

A better flowing air filter does not increase mpg's,a very dirty air filter will actually increase mpg's in any vehicle bought after 1996(gas only),you will loose some power but if driven lightly will actually increase mpg's with up to a 85% clogged air filter.How someone will ask and it's due to the PCM reading the restriction(via engine sensors like MAF,MAP, and O2 sensors) and adjusting the pulse width of the injectors to run leaner,less air equals less fuel hence the better mpg's.

I have the K&N intake (which includes the filter) on my 2012 Compass, I have had ZERO issues with driveability, my fuel economy has gone up and my throttle response is smoother, I also have a custom catback exhaust as well, that may make a difference as well.
