Cost isn't a factor here, just wanting the best option to improve airflow and performance. Also there's a possibility I'll go SC soon and Renntech's system appears like it will obstruct fitment of the SC; does anyone have any knowledge if that's the case?

Thanks in advance!

Since cost isn't an object....go ahead and buy both and then dyno test them for us all

Carbonio doesn't do anything and RENNtech gains will not even be noticed when you're running a 'charger. Save your money.

CheckOrHold

Lol, it's not an issue for one. Not spending $5K on ROW airboxes although I'd love to test both. If someone sponsored it, I'd test them all haha

BLKROKT

I’ve used both. Carbonios are just marginally better than ROW boxes. The RT intake is very clearly better than both.

Dont have before/after dynos, just tons of track time with all three.

Carbonio, you have 30% more intake capacity for better air flow.

BLKROKT

No you don’t, this is wrong

Based on what data?

PeterA90

The ROI on both boxes isn’t worth it. Seriously how can you gauge 5-10 whp on 500 hp car... save your money and buy a blower instead.

also I don’t think the carbonios seal perfectly. They leak at the MAF. Some members needed silicone to hold MAF so they won’t wiggle.

The magic spacers will do more than any air box. Probably 100 more hp.

PeterA90

lol don’t get jim started

Just remove the air filter. Way more horse powers for zero dollars...

The Renntech's did seem to add power but I had a sealing issue like some others that led me to go back to ROW's...... althought the newer version is "supposed"to be tighter compression fit......
for a Sc'er it's a non-starter..... just run ROW's and AFE filters and save the $ for gas ......

I understand why you all are sayign the ROI isn't worth the 10HP gain on the Renntech system, however I'm looking to make a few 'minor' modifications to the engine which when adding everything up gets me about 60HP gains before octane boost. And I think I'm going to pass on the SC and instead get the exhaust system I want with a wide body kit and wider wheels.

Is the latest version the one with the domed/bubble lids (read somewhere on here that the photos currently on RT's site are not accurate)?

Seeing 3 different designs out there:

-Flatter lids, separate runners into the manifold.
-Flatter lids, merged runners/Y-Pipe design " ".
-Domed lids, runner design unclear from the photos I saw.

Then of course there are the MAF location variances. I'm going to give RT a call to try and get some clarity. Will report back anything of interest.

wider rear and bigger tires truly transform the ability to get power down.... I did most of the things I could to maximize NA power .... the E85 kit along with the headers were the two biggest gains... I think 85mm TB's would be the last thing I'd do assuming they ever get a plug and play kit avail with pleniums....I suspect it'd further enhance the E85 gains...

zeus_luis

you think they dont seal perfectly?! Well those member either did the instalation wrong because I have carbonios for nearly 2 years and I have zero issues I disassembled 4 times to do maintenance to the filters and never hade any issues. I did mod the stock oem boxes so many times , I had the spacers too I had ROW too. The carbonio change the exaust note. To my opinion the carbonio was a good investment base on the power modes I have on the engine.

Where did you get your boca CF air intake? The only one I found is this, which doesn't have any credibility afaik: https://modbargains.com/carbon-fiber...tyle-mbin0401/

Jasonoff

You can buy BOCA items direct. http://www.bocadesign.de/w204-c63

I know a couple people have the Boca clone. From what I gather there is not perceived difference from the intake, just small gains from the air boxes themselves.

And regardless of their efficacy, they definitely pretty up your engine bay!

Carbonios are worth about 0.1s/1mph in the 1/4. Same with the GruppeM-knockoff cold air intake.

CheckOrHold

What do you think Renntech's airbox system would run as a comparison?

BLKROKT

I don’t have any data to support an informed opinion on the RT box, sorry. My gut tells me it’s materially better, but I can’t back that up with facts, just hundreds of hours on track.

(I put the RT box on after retiring the car from drag racing - I have tons of data for the Carbonio and cold air intake)

Panzerbiscuit

The RT intake is widely believed by many on here to be the only intake that nets any appreciable HP gains. For the price, you would be better off getting a set of headers, or some exhaust work done, as that will yield more HP, make your car sound better, in turn tricking you into thinking your car is faster.

Mods don't yield cumulative gains in the real world, headers(60hp) + tune(40hp) + intake(10hp) dont necessarily equal a gain of 110hp. It would be nice if it worked that way.

if you want to make your engine bay look nicer, get the carbonio and save your coin.
