K&N filter

[VersaMG08]

I ordered a KN filter online and is expected to arrive on Thursday. I'm not replacing the stock intake box yet, I just want to utilize what I have until I feel like putting a Fujita/AEM coldair intake.Who here has one and how often do you normally clean it?

$?

[VersaMG08]

$3 for shipping and $3.83 tax...total $56.42 It's reusable, has lifetime warranty and million mile limited warranty, so I use it until I get a new car.

[AG]

Cool. Rather buy this one than the OEM one when I need to replace it. Might even turn out to be cheaper.

[VersaMG08]

Yeah, when I put the filter in my airbox, I'm gonna put the K&N decal on the cover itself so it doesn't get accidently thrown out if I ever bring my car in for oil changes and such.

There is a cleaning kit K&N sells for the air filter, it is supposed to be cleaned/oiled every 50,000 miles. I used to do that to my AEM shortram filter on my '98 civic every so often.

Does it really helps with the K&N filter?

Because some cars do make a big difference, but personally, I just don't like wet filters. Plus cleaning them to a clean clean level is another big headache... (Those dirt seems to stay on there forever)

[VersaMG08]

They're pretty easy to clean

- Spray the cleaner on the filter- Let soak for 15 minutes- Place filter under tap water, LOW pressure- Slowly rinse away dirt, air particles, outside elements- Air dry for 15-30 minutes depending on climate- Spray oil on filter evenly, preferably 2 coats

Looks good as new, it takes time but worth it in the long run. You actually save money over time compared to replacing with OEM filter.

I'm not really a fan of the K&N drop in filters - they don't really do much except allow more junk to fly into the engine. I tried one out for a little while and realized that it did nothing, and I felt that protecting my engine was more important than the 2 HP or whatever it said I was going to get.

Read that.

waste of money.

I personally cant speak for filters in a Versa, but I know for a fact that they do make more HP and TQ. It's dyno proven, by indenpendent shops. For example, my car got a 9HP increase just by adding a drop-in filter. So in short, THE DO WORK.

I really have a hard time believing that the filter gave you an ~ 8% increase in HP.

[AG]

Hm... It claims to add power %))Anyways, I was thinking about getting it when I need a new filter just because it would be cheaper than OEM.If its not that good, anyone knows good filters that are cheaper than OEM?

Way to do math. On a stock Evo VIII that would be a 3% increase, but I also have supporting mods.

Stock Evo: 9/271= 0.033 or 3.3%

My Evo: 9/390 = 0.023 or 2.3%

no quite 8%

Math can be hard for a lot of people, so I'll still give you an "A" for effort.

You're posting in a Versa forum - people are going to assume you have a versa and when you mention HP and TQ gains, they assume you are discussing the car at hand, not your other car.

The versa will not see a 9 hp gain from a drop in filter - the EVO has a highly modified engine, running at a much higher compression ratio that can benefit much more from the increased flow of oxygen. I still say it's garbage, and I would rather protect my engine than put on something that allows more garbage into my engine. You can't even feel 9 hp...

First off, I said in the beginning that I dont know about the Versa's gain and that I was refering to "my car."

Second I never said that a Versa would gain 9 hp.

Third, the reason Evo's get a better gain from bolt-on is because it has a "TURBO" not higher compression ratio, and last I read Evo's have a compression ratio of 8.8:1 were a Versa has 9.9:1 so according to your theory a Versa should gain more HP, just saying.

Fourth, K&N filters are not garbage. They are proven by independent shops to flow better, make more horsepower and filter just as well. Most people assume that because it flows more that it lets more crap in, but because it's a oil filter it's able to collect just as much dirt going in to the motor as a OEM filter, and even if there is a small amount getting to the engine, you must realize that it'll be so small and pointless to even reconizing because it'll be burnt up in a fraction of a second and out your tail pipe without you or your car even knowing a thing. Trust me, when it comes to turbo cars, filters are no laughing matter. We take them very serious, because what's the first thing that the incoming air flows through, our turbo. We (people and shops on evolutionm) do "a lot" of testing with filters because HP and filtration is very important!

Finally, are you serious about not being able to feel 9 HP increase. Most enthusists can feel a single HP increase, because they know their cars down to every single horsepower gained or lost, but I guess your not one of us. It's cool though.

A performance mechanic once told me, "300HP is fast, but 400HP is TWICE as fast, and 500HP is TWICE as fast a 400HP, so dont ever take a single HP for granted."

Hopefully "Z-rated Versa" will chime in and back me up.

I don't really believe in the intake mods either. More air through the filter element also means less filtration. That said, the K&N is not a wet filter. Go to the store and handle one, you'll see what I mean. And you don't have to make them pristinely clean either. Back in the day they even claim it works better dirty... which brings us to my first point regarding flow and filtration. Minimal power gain is not worth possible engine damage. The only way to get good power gain with this engine is with cams, exhaust, force induction and software. Most of which are not available... yet. So hold on to your money. Paper filters are not that expensive. Not enough to justify the K&N. The claimed benefits are not proven and they do not outweigh the negatives.

Misleading. The truth is that it depends on the car. I've personally witnessed power loss on the dyno with cone type filter vs. stock airbox on a naturally aspirated VW.

Let's talk about the same thing here - we're talking about a drop-in K&N filter - not a bolt on. WAI's/CAI's and stock airbox filters are 2 completely different things - you do not use a standard airbox on a turbocharged setup.

Again - read this: http://www.nicoclub.com/articles.php?id=180100

Talks about the real "benefits" of the all mighty drop in filter....

19 years old and already a pro...

You'd be hard pressed to find a real "enthusiast" than can feel 9 hp, let alone 1 hp. Butt dyno = about 10hp. Try asking around to the real "enthusiasts" on this forum that actually built their cars.

[WORKS89]

First off, I do build me car I just use strickly Works parts, and I work side by side with them sometimes on designing my car. I've probably done more technical stuff with a car then you could think of, oops if forgot how more complex a nissan Altima is then my Turbo car. Not to mention that I work on a 300zx too. Pain in the a$$ By the way I've taken and passed tech classes on engine performance, but you know what, I dont have to justify myself to you.

Hey, Evo's use plastic boxes too. Not like our cars come stock with a CAI or something.

Once again you have misread my post, Im not talking about CAI's, the gains found on my car was 9 HP. I've tested this, my class tested these filters, independent performance shops (builds 1000whp cars) test them, hell go dont to a parts store and look at the display. No matter what you say the K&N flows more air while still remaining safe.

I want to comment on CAI's really, be careful! Unlike drop-in filters, these can potentially be very dangerious for your car, and are not always tested in really world conditions. Example: Toyota celica owner have been experiencing hydrolock lately do to poorly build intakes. Some CAI's have been know to throw off MAF sensors in cars causing to run bad and loss HP. We tested a Honda civic in our class with a CAI, it lost 3 HP. Another test was dont showing that CAI's dont always do what they're suppose to do. A CAI was put on a EVO IX and did 3 passes, on the 3rd pass the air coming in throught the intake was at 120 degrees, then they whiched to a stock box with aftermarket drop-in filter, and did 3 pass (remember the car is already hot) on the 3rd pass the temp. of the air was 95 degrees. I'm not talking done CAI's I'm just want to say to everyone, be careful, and be sure to research your intake before you buy it.

Before you try again to get the last word in, answer this:

This is not a Evo forum, is it?What works on the Evo will always work on the Versa too?

Less filtration = more flow. That's a fact.

I like mine I drove to florida with out it to break the car in. Then on the way home I but it in and seen a difference in gas mileage. I check mine at every oil change and it still looks good as the day I bought it. Every one has there own opinion.
