this is on area that I disagree with Dave here. The Stillen is probably as good or better than the oem airbox. The v-stack is designed around a huge 6" diameter. But I've run both and have already stated my opinions. Really no need to rehash it for the 10th time.

To the OP, sorry but I don't think you've searched enough. If you have't read that thread, you need to. If you have already read that thread, not sure what questions you would have or what additional conclusions you are seeking. Probably no one is going to dyno these as the gains or delta differences are well with dyno error so it's all "noise"

 

^ You're on my **** list this year, Chief!

 

OP....Try em all, and see what you like the best, that's what most of us have done. They are all basicaly the same as far as gains/losses/intake temps are concerned. You aren't out flowing the OEM airbox, rev up or not, so don't expect any real gains from anything else including a drop in.

IMO.....rev-up box with a dryflow drop in if you really want(Amsoil and i believe AEM or HKS makes one). K&N doesn't filter well thus the reason it "flows more". But if you aren't outflowing your factory box and filter to begin with, then why sacrafice filtering?

Take a look at yrou factory airbox design. It's already a CAI, more so then a short ram, it just doesn't look "cool", or make a neat noises. It's straight through, with a large panel filter, and is completely sealed off from the engine compartment. Obviously you still have radiant heat to deal with. But i can't imagine a more efficient design over OEM.

<----2 cents

 

I usually use Stillen... but I bought the revup back half intending to do before and after with Stillen, stock revup and stock non-revup...

car was in body shop for several weeks and when I got it back I ran the revup box for a week - car seemed a little lethargic, but I hadn't driven it in a while and ecu had been reset (from long term bat unplugged) so I didn't think much of it... after a week I put the Stillen box on with pop charger - and noticed much stronger pull in lower to mid rpm... the car felt the way I'm used to.

So the revup box has been in the garage every since and I'm not even going to bother with dynos (because my mind it totally made up).

I don't care to debate this with anyone - I run what works best on my car, and the revup box is not it.

btw it is for sale at a loss... I have no need for it, but I'm glad there are people that do... $50 (one week old, but had been painted)

 

My intake temps are within a few degrees of stock. Not a coincidence. Stillen airbox does a good job shielding heat.

 

Here's my .02 I have tried the stock box, the revup box, and the JWT pop. Kept trying different things because I still wasn't happy and thought there was something better out there. Haven't tried the Stillen, but a lot of members here have it and like it. I opted to try the R2C and have been very pleased. Has one of the best filters on the market and the box seals against the hood to help prevent heatsoak. My mileage has gone up a smidge since I installed it, and of course it makes a healthy sound over 4000 RPM's. If you are interested contact Marinelli Motorsports for a great price. W/O their tube it's about the same price as a new popcharger.

 

Thanks for all of the responses guys.

I have indeed looked through that thread (and it helped too) but I was wondering if there are any direct comparisons b/t the Revup and aftermarket intakes.

Plus I don't feel like doing all the extra installation work for the long tube CAI...so I crossed that out awhile ago. I just haven't heard much about the R2C intake ( link )

Does it change the sound noticeably versus the stock air box? Could you elaborate?

I've heard the K&N Filter recommend and not much else...so I'm not sure.
Yeah, some of the better aftermarket intakes and the stock seem to be similar in performance (what I've read)...but I can see what you're saying. Hmm..
That's good to hear...do you think the intake alone makes the difference for your car? Or would your other mods play a part? (what color is it painted?)

What did you think of the stock vs revup or revup vs R2C?

So you haven't noticed any loss in power with it? I like the way it looks... Already contacted him for the cheaper price too

 

I'm confident that the success I've had is a combination of the mods I use... I have no idea how any one thing wold work on another car - but what I'm using works very well...

painted metallic black - it was an attempt at black chrome, but the shop didnt quite get the look I was after - the color in my engine bay now is what I wanted... the quality is superb and the color is actually nice - it just wasn't what I was after... and as it turns out it didnt matter since I don't use it (otherwise I would have had them repaint it like some of the other stuff) ~

 

Judge for yourself. The setup is the Revup airbox, stock G-tube, slightly enlarged Powerduct cover, bypassed lower airbox resonator, HR y-pipe, and 06 sedan midpipe.

Heavy throttle

Heavy throttle (VDC on, dumba$$!)


50% throttle then heavy throttle

 

A'PEXi makes a drop-in now too...

 

Sounds nice...I assume you like the G tube sound over the Z tube right?

I guess I need to keep looking for videos on each intake and see which sound I like the best I suppose...but like I said before, none of the R2C. :/
---

How does A'PEXi compare to K&N?

 

A'PEXi is dry and they've been known to have the best flowing dry cone filters, so i'm sure thier flat panel is great too.

 

In terms of sound and gas mileage R2C>revup>stock. In terms of performance there is no noticeable difference.

 

Avoid any metal if possible. ESPECIALY the intake tube. Plastic gets hot too, but it doesn't retain the heat like metal does.

 

^how long have you had that intake?

How do you clean the filter?
