Drop-in K&N filters - a waste of time/money?

Nismo 370z · 01-16-2009, 02:15 AM

^ Do u think the VVEL on the VHR's do anything to the ECU when adding aftermarket intakes on the car? I mean that could cause a drop in hp from what people are seeing right?

Here they are for $83.90 a pair

No... CIA will not affect that. The air intake temperature sensor comes after the filters. Meaning, the temperature of the air will not mess with the computer. It would be no different than going from cold weather to hot weather. The AIT senors will adjust accordingly.

K&Ns are a waste of money, IMO. If you're going for track use, you MAY get 1/100th of second better times, but they won't be as consistent. I got more consistent times with paper filters than I did with the K&N. Also, they're REALLY made for off-road use.

Not all oil-based filters are good.

The Stillen gen 3's were producing a good 16-18 hp on various cars. I think these would be a great addition.

Those are Stillens claims. I dont think any intake setup will add 16hp. If we are lucky we will get maximum 5-7whp.

In for an opinion after install.

semtex · 01-18-2009, 08:26 AM

Haven't really driven it enough since install to form much of an opinion. Initial impression is that throttle response is slightly improved. Nothing earth shattering though, not that I was expecting any huge difference. This might sound stupid, but for me, this was more a matter of principle than an expectation of real gains -- I just don't like paper filters!

Will look stock dude. Its stock air box with a drop in filter. Go look at a stock motor, there's your picture.

I had a drop in on my 350z before I got an AEM CAI. I liked it.

Intakes wont be any noticeable power though, just gives a louder growl out of the engine.

semtex · 01-19-2009, 08:17 AM

I should have probably phrased my original question about whether or not it'd be a 'waste of money' a little better. I know that we get better airflow through a K&N vs. paper filters, so from that basic standpoint it's not a waste of money. What I was really trying to work through in my head, however, is how far off we are from getting a good CAI from, say, Stillen on the market. Because if we only need to wait a month or so before they release one, then it'd be a waste of money to spend $100+ on drop-in K&Ns only to take them out just a few weeks later, not to mention spending another $400+ on the CAI. On the other hand, if it's going to be like 6 months before a decent CAI will be released, then it makes more sense to go ahead and get the K&Ns. Of course, I'm guessing that none of us are clairvoyant about future release dates on this stuff, so ultimately there's no way to answer this question objectively anyway.

Well... If I had my Z now, I would get the K&N's. I would not settle on a CAI until we have a bit more tangible gains that are dyno proven. Just because the Stillen made power on the G37 doesn't mean it will make power on the Z.

Just my thinking...
