if you get one be sure to get the plain paper filter had oiled filter and maf became a prod got paper (no oil) and all has been fine for a year or so have evo air box all is fine

 

Evo air box system uses a paper cone filter?

 

I wouldn't hesitate buying a v-flow. I have had mine on for approx 4000 miles without any problems at all. I have the newer version with the waffle and a dry filter, so that may be the reason I haven't had a problem. I feel that it adds some power compared to the OEM paper filter, and I wouldn't switch back to stock for any reason. As far as the noise, there isn't much of a difference from stock IMO. I do hear the diverter valves working now, but other than that, it's the same as stock.

 

I have a slightly used EVOMS V-flow - if someone would like to buy it, make me a reasonable offer (pm me)
(The class we race in does not allow this modification, so I had to remove it and run stock)

 

Hi

Can you please email me on wojtecki@gmail.com

thank you

 

Agreed.

I'm a Protomotive guy as well, but even I'll admit that when my car was a IA Stage 2, the V-low (with dry filter) gave me some noticeable power increases. Heck, as far as I know my Stage 2 trap speed of 126 is still the fastest ever for a K16 car.

To generically imply that the V-Flow won't add value to engines making under 600 hp is ridiculous. It'll add value at any horsepower level.

 

To generalize that the v-flow will add power at any hp is ridiculous

 

I don't buy into the Vflow working.....All I ever got from it was CEL.I am sure it has worked for some.......Just not me, it was a waste of $$$, I gave it to my buddy and he also went back to stock. Dan from Vivid Racing has a new Carbon Fiber box coming out shortly, I am waiting on that one.. I cant lie its looks great.

 

John: I ran an EVO V flow on my preivous car....and it made no difference in performance at all....it did provide some pleasing sound feeback thru the filter, but that's about it.

I have never raced or built a racingn engine....so my comments were from personal observation and talking to other P car guys at the meets. Some swear by the advertised HP enhancement....but to be perfectly truthful, with all the threads on blown MAFs and other issues, I can't seem to justify spending that kind of money on a product that has a history (not with everyone) of causing problems that the stock unit doesn't cause. If it does cause a problem, you have recourse thru the dealership....but not if there's a V flow on it. I just don't see the value in taking a chance, and the pro/con comments on a number of forums would seem to bear that out. MAF's are not cheap....and Im informed that unless you're going for the big HP numbers, the stock unit can adequately handle 550 to 600 HP...

 

wanna buy some headers to go with your air box?

 

John, My guess is you wouldn't notice that difference with the other mods like DVs/Wastegates/tune/DGI exhaust... I know when I installed the AP box, all I got was noise, and a CEL. You might have cleaned up your throttle a little bit and felt like it was spooling quicker, but more effective mods (Like DVs/wastegates) would pay longer term benefits, and from what I've seen of the filter elements in these aftermarket boxes, the surface area for filteration isn't there... Not to mention the biggest limiting factor of all, the throat of the MAFS tube at the TB... Unless you change that size, you're sucking the same air down the same hole...

I'd have to see an independant (NON-VENDOR) dyno of a before/after of any of these boxes, because I'm not buying that it's a large gain... We'll have to agree to disagree on that one...

Oak for President...

 

Oak's too smart for president...pull my finger

 

I have an EVO box on the way only because I am going to be swapping MAFs to a Ford setup. Though at the hp level i am at it should work fine although that Proto intake kit is super sexy!!!

 

Our Agency Power airbox has been out since October ish. We have sold 75 intakes to customers here on the forums and internationally. We have not had 1 MAF failure caused from our air intake. Out of those 75 we have had 2 returns for customers not liking them. We have a new batch being made right now which has alot better QC to make sure parts are something you will want in your 996TT. We have tested them on 3 996TT with K16's and then 2 996TT with K24's. 1 was a Tip. All cars netted big peak HP and TQ gains in the mid range RPM's. There are many prominent members on here that run our Airbox such as Tom Kerr and others who run their cars heavily on the TRACK and see results.



Also we have a new design that is being released in the next week. This box is all carbon fiber. The process to make these is a bit tougher. So first come first serve. Same performance, cooler look. It will retail at around $900 meaning street price of about $825. If interested, PM me.



Both air boxes will FINALLY have an integrated and optional purchase of a second air snorkel too.
