Air filter to boost HP??

I heard somewhere that there are Air filters that can add some 10 -15 HP to the Xterra. Is there any truth to this?

Yes, and the fabled "Type R" sticker is worth another 5-10hp... ;>
Naw, seriously. Get yourself a K&N filter and you'll forever be thankful. It's much more efficient, especially so when it's dirty - as compared to a stock paper filter. It'll filter out a lot more stuff, last a lot longer - and yes, increase horsepower and mileage.
But it certainly won't add 10-15hp! More like less than 5hp. It should increase your gas mileage ever so slightly as well.
Again, it's more efficient, and all-around better than the stock filter. It'll also last forever.

You must not have put the K&N sticker on the back of the truck...that itself have me about10 hp. ------------------ Joe No Officer, I'm not naked. I'm wearing my Xterra.

I heard that fuel economy actually suffers when you add the K&N. Maybe that was the pop charger. :}

I wasn't going to say anything till I'd gone thru 3 tanks of gas, but the K&N does seem to be working. I've been getting at least an extra 1.5/mpg since I've installed it. I know that might not seem like a lot, but when it'd been at 16/mpg, every little bit helps! ------------------ 2001 XE-3pk Auto Just Blue 4x4

There's something wrong in the analysis, then - because replacing the stock filter with a K&N improves mileage, if anything. Granted, like I said - you won't see dramatic changes, but they are there.
The other day I did a good mix of highway and local driving, with the A/C on 75% or more of the time, with two passengers (three people total). The tires were set to 34psi (a touch too high, IMO - go for 32). On the highway I drove anywhere from 65-80mph and I got exactly 17mpg. A couple of times I romped on 'er to show it off to the passengers (my parents). If I took off my BigPowderHound I think I could've gotten even a little more.

It's a K&N Filter, available from xterrastore.com or xterraparts.com. They have a size made for the Xterra. When you install it, keep in mind that you won't need the foam glue-on strips that come in the box.

The hp gain is proportional. 10-15 hp might be seen in an engine that already puts out a lot of power, but not on an X.
There is no such thing as cheap (tangible) horsepower.

You guys are great! I like this board because everyone is helpful and honest. thanks for the advice I will get one right away, it sad that I feel like I should have to replace a filter (nissan) with only 100 miles on the car (yes I already put that much one and it hasn't been a week yet). Not to start up anything else but whats this talk about adding an exaust to get more power. Just kidding!! I read all kinds of stuff on here and other places that makes me wonder how much truth is to anything. All I know is I love my car, but the gas mileage and power do kind of lack. Now I know where the money I saved buying the car is going to go. GAS!!!!! Seems like just to take it on the long trips I might have to add in the price of the frequent fillups. Go any where, spend any amount on gas that should be the slogan for the X.

Don't fret too much, it's quite normal in most vehicles to upgrade to K&N, even on Porsches. If all the parts in the X were upgraded, like a stock filter to K&N, they'd be more expensive! Please post your impressions when you get it. mikeT ------------------ 2001 SE 4X4 Rain+Dirt!

Not to beat a dead horse, but the performance gain with K&N is way debatable. I took my K&N out of my Frontier and never did put one in my X when I got it. I think my mileage actually got worse and my idle speed was always way too high. I had to step on the brake hard to keep the truck from moving when I was stopped at a light. Took the K&N out and everything was back to normal. I like the re-useability of the K&N, but without an aftermarket exhaust, the performance gain is more imaginary than anything. All just my .02 cents.....and some pocket lint to boot.

Well, I have two K&Ns in my race car, and one in the Xterra. It works for me - mileage, performance, longevity and effiency are all up. It's just a better filter. But hey, to each his own! Shaddup, Joe. ------------------

I was able to locate the filter locally for 2000 Xterra but none for the 2001. It should fit the 2001 fine right?

Yep, no change between '00 and '01.
Pep Boys has 'em for under $50. I've seen about $36 online, but after shipping it's pretty much a wash.

I got mine for $45 at Pep Boys and it is the same filter as the 2000 Xterra and Fronteer uses. ------------------ Joe No Officer, I'm not naked. I'm wearing my Xterra.

not to keep this thread going longer than necessary, but I got mine at Pep Boys and it was right at $45 as well. I've got nothing but good things to say about them.

has anybody tried the JWT Pop-Charger from xterraparts.com and if so, does it work better or worse than just replacing the K&N air filter? Are there better solutions out there for air induction systems?
Does it really matter about getting a different exhaust like the cat-back exhaust?
