Drop In Filter ... I had some extra cash (very little) so I decided to buy the K&N Drop In!!!

Yes I've heard of the "possible" filtration problems ... but I did want to try it out!!


Quite Frankly, I'm Impressed ... after a WHOLE night of driving, and almost Half a Tank of Gas used ... I've done a Lot of testing in one night!

Results:

Increase in Throttle Response, NO JOKE ... I can feel a Difference, when I step on the Gas, the car gets in motion a bit faster! NOTHING DRASTIC of course!

Very slight difference top end, MERGING on the HIGHWAY!!!

More SWISHING sound hehehe ...

I'm pretty happy with the $60 Canadian I spent ... I can feel a slight difference ... Hey ... its only $60!!!

 

If you threw in a bit more you would've had the JWT. Then you would've really liked it. Hehehe...

 

But for a mere $12.00 US more, he could have a Air Silencer Cold Air Intake that performs as well or perhaps even better than the JWT or SI. Contributors to this forum steadfastly ignore the Air Silencer CAI. They're probably p!ssed off that they spent a whole lot of money on a JWT Popcharger or SI or Place Racing CAI when a simple, inexpensive mod could have given them equal or better performance, but the results speak for themselves. If I had to do it all over again, there is NO WAY I would have purchased an aftermarket intake until I had given the Air Silencer CAI a try.

Check it out, Empz. The thread is in my sig.

 

Air silencer CAI is interesting... I want to see pictures of the setup, but I guess he didn't get to them yet.

 

Man... the way you be pushing that thing its like you get commission. Someone needs to do a pictorial conversion FAQ.

 

I wish I did, punkdork. Actually, I'll bet somebody could come up with a kit for it and make a few bucks in the process. Basically all you'd need is three pieces . . . tubing, a clamp or two, and a K&N or Amsoil drop-in air filter. Add a few simple instructions and a couple of pics and you'd be in business!

PS: If you decide to do this, don't forget where you got the idea from.

 

You guys are the Best ... THANX ... I'm gonna go buy the parts this weekend ... and my Buddy is gonna help me do the install ... its always better to have 4 hands instead of 2! hehe

This idea looks REAL sweet ... U guys just saved me BIG bucks if it works ... won't have ta spend another $160 for a damn CAI or POP CHARGER! hehe

 

And take some pics of the install while you're at it.

 

Sounds GREAT!! But why do I need the drop in filter? I plan on doing this sooner than I can get a drop in, so will the stock filter work temporarily?

 

In a word, yes! But you won't get as much air flow as you'll get from a K&N or Amsoil. Still, you should be able to notice the difference even with a paper filter.

 

Cool! Can you describe what I need and how to do this? I'm going to see if I can do it tomorrow. Thanks in advance!

y2kse,

Have you dyno'd your findings yet compared to a true CAI setup? Has anybody? I am curious because I am going to start my performance mods soon and was seriously considering a PR CAI.

Do you have to reset the computer (e.g. disconnect the battery) to realize the gains when making this change?

Also, why use this "box"? I have not actually looked at it myself: I have only read the posts. If you are changing the input hoses into the "white box", basically, then why not by-pass the "white box" altogether? Perhaps if I get in the engine compartment and dig around my question could be answered.

 

To answer your questions, mdeal, (1) no-one that I'm aware of has dyno'd their findings compared to a "true" CAI because, among other reasons, the Air Silencer CAI was just discovered, (2) I doubt you have to reset the computer to realize gains when making this change, and (3) the Air Silencer CAI bypasses the "white box" altogether.

 

Be careful where you put the intake - you don't want to suck up water - otherwise a great idea.

 

I have used the drop in in my 95 Max and 2000 I30 and just like Empz have notice the same positive results.

I was also concerned about the letters/posts about the "filtration problems" and wrote a note to K&N and here is what they wrote back:



Dear customer,
It is a fake. Note the date, 1995 and still going around. How do I
know you ask? We DO NOT make filters for mining or construction equipment.
If he used a small Honda filter on a turbo charged V12, no wonder he had
problems!!! Here is the truth to it.
Our filters are tested by an outside, independent laboratory. They
have been proven to stop at least 99% of particles on a SAE dust test. This
test uses particles in the 0 - 5 micron range and goes up to 20 microns.
For comparison, a paper filter also stops 99% on the same test and the OEM
minimum standard is 96%. Foam is generally the worst media with a typical
efficiency rating of 75 - 85%. To get higher ratings, the foam must be more
dense and therefore way more restrictive. The "tack" characteristic of a K&N
allows for increase filtration without loss of flow as well.
The testing procedure used is SAE J-726 using ISO Coarse Test Dust.
This test is the standard of the air filter industry. The test procedure
consists of flowing air through the filter at a constant rate (airflow rate
is determined by the application) while feeding test dust into the air
stream at a rate of 1 gram per cubic meter of air.
As the filter loads with dust the pressure drop across the filter is
increased to maintain the prescribed airflow rate. The test is continued
until the pressure drop increases 10" H2O above the initial restriction of
the clean element (in this case .78" to 10.78" H2O). At this point the test
is terminated. The dirty filter element is then weighed. This weight is
compared to the clean element weight to determine the total Dust Capacity.
The amount of dust retained by the filter is divided by the total amount of
dust fed during the test to determine the Cumulative Efficiency.


The K&N filter achieved the following results:

Dust Capacity: 305 grams

Cumulative Efficiency: 99.05 %

We got started over 30 years ago making filters for motorcycles and off
road racers. The filters did so well that these guys wanted them for their
cars and trucks. We started making filters for these applications and here
we are today. If they did not work, we would not still be here and growing
every year.
We now make filters for Chrysler/Mopar, Ford Motorsports, Edelbrock,
Rotax Engines, and Harley Davidson. We come as original equipment on the
2000 Ford Mustang Cobra-R. We even made the filters used in the Apache
helicopters used in Desert Storm and the US Marine Corps new Osprey
tilt-rotor aircraft. If they work in these conditions they will work for
you. This leads me to the Ford post. The dealership may not void the
warranty per Federal laws. The Moss-Magnuson Warranty Act of the Fair Trade
Commission states that if a part is not covered under warranty, the consumer
may use any brand they choose to. Air filters are not covered under the
warranty so you are free to use any brand you choose. The real clincher is
the fact that Ford carries and sells a line of our filters at the
dealerships. We make the filters for Ford Motorsports and they even took
out a 1 page "ad" in our catalog. In fact, we are original equipment on the
2000 Mustang Cobra-R. I find it highly unlikely Ford would endorse a
product that causes problems with their vehicles. In fact, Honda and Toyota
only recommend K&N filters when using aftermarket high flow filters as K&N
is the only brand of filter the oil does NOT come off of.
You may post any or all of this if you like, in fact, it would be
appreciated. I would be interested in seeing the responses. Bottom line,
the internet is opinions not facts. Don't take all you read as accurate.
Thanks for writing, Rick

 

Point well taken, wdave. Fortunately, it is practically impossible to suck up water with the Air Silencer CAI. The reason, of course, is that the cold air inlet attaches directly to the stock air inlet. It doesn't replace the stock air inlet. Now as we all know, water is heavier than air. As a result, even if the cold air inlet becomes completely submerged, the stock air inlet will still permit air to enter the throttle body. The only way water will enter the throttle body is if both inlets are submerged . . . which, of course, means that the vehicle would have to be submerged to the hood. At that point, I doubt anyone's chief concern would be water entering the throttle body!

In my opinion, the Air Silencer CAI is probably the best bang-for-the-buck performance mod available for 5th Gen Maximas. I wish I had known about it before I purchased my SI.
