how much of a difference would installin a K&N air filter make as far as fuel efficiency n performance are concerned?

It would likely improve both a little. Probably not a noticeable change, though. Mabye 2-3hp. A full intake would be more effective in combination with an exhaust, if you want an improvement you can feel.

 

I didn't notice either; I mainly bought it is a cost savings measure because just buying two stock filters would cost more than this reusable one.
Don't expect a world of difference.

 

It could be just me but after I installed mine, I felt like it performed a little bit better... probably just my mind justifing the purchase but hey... in the long run I will save money too because my baby is paid off and mine till the end...

 

I can tell you that when I installed mine it made a good difference, mpg went up by 2 and the top end was higher, plus, I don't have to worry about buying a filter for the rest of the life of the car.

 

I felt maybe slightly better throttle response and maybe better upper end power, but that was it.

 

very very minimal

 

i notice a bit more pep when i step on the gas but it's just a bit. i got it for not having to buy another filter.

btw have any of you guys put on that k&n sticker on ur air filter cover that lets people know that you have an aftermarket filter? i haven't just cuz i'm thinking maybe some no-good acura mechanic might swap it out with an OEM one when i bring my car in for major servicing.

 

I put the sticker on... and when I bring it in I will remind the service people of its exsistence... and it will be checked when I pick up the car too...

 

i think if you drive on the freeway most of the time, you'll probably notice a little difference.

 

It felt a bit smoother after I dropped the filter in. Maybe just my imagination. But I am positive I gained 2 or 3 mpg!
