1. Dynos show they do add about 3 to 5 RWHP.

2. There are many more oiled air filters in use than dry filters.

3. Yes they do flow better and as for "not very good at filtering air" that's a load of

. Oil filters have been in use since the early 1960's and there has NEVER EVER been the failing of any engine as a result of using oiled air filters, so their filtering must be doing something right.

You know I first remember when this misnomer about oiled filters inability to filter the air well first started.....it was when the first manufacturer of those thin rubber filter covers first hit the market about a decade ago. All of a sudden all their advertising propaganda suddenly sprang up overnight. And like the usual thing that happens...some armchair uninformed reader picks up the advertisement and then starts to propogate it all over the auto forums...and then pretty soon the false misnomer becomes "the truth" as a result of just the shear volume of spreading it all over the web.

The Z store has the K&N's for $41 each. I just ordered mine on Friday.

Installed the K&N's this afternoon. I only took the Z for a short drive, but throttle response does seem to be a bit better. From inside the car I can't tell a difference in sound under acceleration. I will report back after a few hundred miles.

Do you guys remember what part number they are?

TonyBPD · 11-02-2009, 02:50 PM

K&N Part # 33-2399

drop ins and modshack vent diy should get good results for litlle $$$$$. drop ins get about 4-5 hp gains alone and the diy vent should gain a couple extra with the better air flow to stock box. I plan on doing the diy in the near future and thats it for my intake till the SC.

I got mine at Pep Boys. Down here most everything's more expensive (transportation charges+politicians' duties/taxes!) than at the Continental U.S. I have no regrets on the drop in unit, so far. BTW, the throttle response IS better, now that you mention it. I hadn't thought of it...The power band does feel more beefed up, if I may use that expression! The extra MPGs was my main concern, though (I'm 60 years old). Greetings!

Got mine in the mail today. I'm off the next two days but will add any pertinent comments after I drive it for a week or so.

j.arnaldo · 11-13-2009, 11:54 AM

...any comments, tin-man?!

Put mine (K&N) in yesterday and noticed a very subtle (very slight) difference. I need to drive the car a little more to really figure how much of a difference.

After 16k miles the old (OEM) filters looked pretty bad...yuk, glad to toss those.

I really like being able to clean and re-use the K&Ns......nice.

j.arnaldo · 11-13-2009, 12:22 PM

Don't forget the recharger kits, dudes! I clean mine out once a year (my wife's Pathfinder's, and my Z's).

Been driving a few days now and I really can't tell any difference. I thought there'd be some placebo effect, but not even that. Fuel economy via the onbard computer seems to be the same too.

Chan Chee Hoe · 11-15-2009, 05:23 AM

Oh yes,i also use K&N drop in filter in my car,very 'slight' power increse is noticed,only thing is can wash & reuse,save $ & enviroment[less rubbish],fuel economy is the same...

From the info' provided by some of the more knowledgeable dudes here, the difference seems to be in the torque power band; a slight improvement, still an improvement. Where I did notice a sweet difference, was in the MPG. I went from 11-12 days on a tankful, to 14-15! That, in and of itself, justifies the modest investment.
