I've got a 2002 Maxima SE and I was wondering if a K+N air filter would be good to add to the car. I've asked my dealer and he said it would be ok and wouldn't avoid any warranty but might throw codes. Has anyone had any experience with a K+N air filter in an 02' Maxima? Does it improve fuel economy? performance? I'm not expecting much....I just want to improve my fuel economy without any trouble....thanks.

 

To be honest, you should look at it from the perspective of not having to buy a filter again...any benefits (which will be small) should be considered a bonus.

 

Hell, after 30K miles of use, or approx two years, I'm just gonna freakin buy a new one, screw that oiling crap. 40 bucks every two years, big freakin f'en deal. yea baby yea...

also, you can search K&N and it will come up w/ a bunch of hits.

good luck!

The K&N might help throttle response a little. I have one and like it. It will take a combo of things to increase fuel economy, K&N filter, synthetic oil, and proper inflation of tires. Most important,
time and distance beyond 10,000 miles.

 

I got one for my Max and its great! Noticed slight increase mpg. And a quicker acceleration. Go for it!

 

is this for sure? because if it is i will go out and buy one.

 

I have one too, worked great for me.

 

Not that much faster acceleration, but enough to notice it when you go back to the paper. Also, I got gas mileage increases of about .5-1 mpg per gallon, so it's not a huge amount, but enough to save a few bucks in the long run (I know because I track every tank). Not a bad buy for $40.

 

how do you properly install the K&N? i dont wanna void the warranty.

 

The Maxima Air filter is very easy to replace. Just undo the two metal snaps on top of the box and lift the tray. The air filter fits inside the tray and therefore the K+N should fit right in there, however there may be gaskets to use to make sure it fits properly. I'm going to go and get the filter today.

 

I put one in my 02 Alti SE. I picked up 2-3 mpg in mixed driving. Maybe a little increase in power..more mental (wishful thinking) on my part than anything. Quite a few people have blamed the K&N for MAF problems...including dealerships. So if you have a problem, before you take it in for service...Keep the old filter and swap them out.

 

On a 2K2, you undo the metal snaps. After undoing the snaps, slide the filter carriage out. Take out the old paper filter and install the gaskets for the K&N to go in. Install the K&N and then put everything back.

I have one on my '02, had one on my '94, and had one on my '88 Caprice. Need I say I love having them.
