here are some pix of the 'gap'.

Rockin!

Thank you x ∞ !!!!

They say a picture is worth a thousand words... well, that picture is worth twice that plus dozens of hours of searching and reading and head-scratching and nose... nevermind.

This is great! You have no idea how long I've been looking for something like that. No problem! I can seal that off easily. Thank you again for taking the time to contribute so much! People like you and Gothchick and Wired make this forum rock.

You guys are assembling the ultimate end-all thread of CAI and high flow filters. They said it could never be done, but heck... here it is!

Great information! Thanks to everyone who is working on this issue and reporting results.

Good thread fellas! I would def agree that the Jim Wolf Pop Charger
is very prone to heat soak, I took my car out for a spin yesterday at around 3:15 pm. The car had been sitting all day up until this point and noticed that from the get go if I layed down the gas it would feel a bit sluggish until I hit highed speeds 3rd/4gear +. I belive the outside temp was in the low 80's here in VA, not very hot but its enough to see the change in performance when you are running around with this JimWolf kit in a somewhat hot enviroment. My engine did run idle for a few minutes before running but still I will have to consider going with something else, I noticed this problem last summer with the pop charger. I do also do feel a difference in the engine as far as performance goes when I leave for work early in the AM when its nice and cool out not hot AT ALL! This is just something I have seen over time and because of the times of day I drive my vehicle. Iam no engineer with degree but it's just my .2 from my personal experience!

The stillen has an opening at the bottom, but I believe (and I may be wrong) that this is there for a reason. I think it's there to keep air circulating through the airbox chamber portion. The GRUPPE_M intake I had back in the day had a similar opening at the bottom, when air is being pushed through the duct in the core support towards the filter, you need a constant circulation of air or the intake system will starve.

Picture opening a window of a closed room. Then, with the same window open, open a door to the same room, and you should get a current of airflow. I believe (and again i may be wrong) that this is the purpose for such openings...


Sound wise, i've found most open element filters to have a similar sound, however the longer the pipe (such as on nismo or AEM etc), they tend to have more of an echo effect and the intake sometimes sounds louder than under hood intakes IMO... And i've gone through 5 intakes, too

Track

Very good point! And great info to know about the Gruppe M too! Thanks for the info and your time. I will definitely use this information in my decision-making process once I get the Stillen in my grubby little paws.

Thanks again. To everybody who has contributed in this thread!

This should be a sticky. I've learned more about the CAI issues in this thread than in the dozens and dozens hours of searching I've done in the last few weeks.

Screw it, next time newb asks "what's the best intake" I'll just say stillen

Although I am still apprehensive spending $80+ on a piece of plastic that I could make myself if I felt like it.

Hence stillen = "stealin"

That's exactly why i bought the popcharger first. Then i got and realized how much i didn't like it. Then 6 months later i said screw it, i'll just buy the one i wanted from the start.

Yep, I've been too lazy to get out the arts & crafts materials and start cutting plastic

From what I've read (most of it written by you!), that is not too bad of an answer. It seems, at least, that we have here two very good options: One for the driver concerned about cost and wanting the best sound and growl from the engine, and one for the driver who is more concerned about the engineering and the physics involved than the cost or "growl," even if that involves doubling the price.

I know you were kidding, Mike, but seriously, it looks like this question is really getting buttoned up here with two very good, distinct options for tuners at each end of the spectrum. I never thought this would be possible and people have joked about this for years, but thanks to some fine research done by yourself and a few members, we really seem to have some answers now.

Um..... Has anyone checked the Weather Channel? I wonder if it is snowing in Hell. No reason.

Has anyone actually tried using the Varis Duct along with the Stillen box and filter??
I would like to see how much of an improvement in the butt dyno, sound, and temp.

Wired 24/7

It should make a difference at speed, but not on a dyno. Sound = no difference really.

I think this was asked in another thread and I didn't see an answer there, but would the JWT filter work in the Stillen box (size wise) and would it even make a difference. The JWT filter has an open element top whereas the Stillen filter has a closed plate top.

Track

If someone measures the dimensions of their JWT filter element I'll measure and report the inside dimensions of the Stillen air box when it arrives (already ordered it) and then we'll all know.

If someone gives me their Stillen air box, we'll all know jk. i'll get it to you when i get home.

JWT Pop Charger Dimensions.

World Famous Z

The JWT filter is 100% exactly the same as the Stillen one, it's just that the stillen is a true K&N filter and red, while the JWT is blue. JWT filters will fit the stillen air horn adapter.

and you can't go wrong with a K&N filter IMO...

And yes, a air duct such as the VARIS should help feed some air to your airbox too, but again will only work at higher speeds

Track

That's a tough call on which would be better.

If you had a Varis duct, then the Stillen seems to have the advantage since it is a straight shot from the duct to the metal plate on the front of the stillen. The plate may increase the longevity of the filter or keep the middle from crudding up before the rest is halfway dirty (just a wild guess).

Without the Varis, the JWT design would probably make better use of the factory cutout and perhaps even make a better intake sound, since the high pitched "slurp" would be a very "directional" sound, an open end would prevent as much of the sound from being dampered by the thick plastic enclosure (this way, the sound would be directed through the factory opening and to the outside rather than the thick plastic walls of the housing).

Again, just speculation... (but that's all we can do so far).

alot of info on this thread! thanks

my conclusion to this is;

stillen air box + popcharger filter + varis duct = best intake

I have also decided.

My stock 06 airbox with CF Z-tube
A custom velocity ring for the inside of my 06 box

can we just order the stillen airbox without the filter?... where?
