They look kind of stock form, like someone modded the intake box into heat shields. If the dyno is correct, thay seem to hold up well, but something seems askew.

the air filter is a totally different design

take some time to read this

2007-2008 Infiniti G37 MaxxFlow Cold Air Intake System | R2C Performance Products

and this about the filters

Technical Advantages | R2C Performance ... World-Class HIgh-Performance Intake Systems & Filters

it's interesting, shumby got me interested in these

so what do you think??

Those filters look smaller than the stillens. How can you have reduced factory restriction, yet have a dyno similar to the Stillen, yet have smaller filters?

Is this just my perspective or the angles of the pictures? Or is stillen using a filter that is so large it is losing power?


Edit: I think they are BS. Just because their filters are similar to the ones in an Army tank doesn't mean **** to me.

They sure do talk about cotton gauze a lot.

stillen uses K&N oiled filters...to me they look the same size

IDK man, give them a try. I think I'm missing something here. :icon14:

they do give a nice rumble

I like the black pipes on them too... With the white filter...

I just dont get what that shield is for in front of the intakes... I mean if the idea is to get them out of the engine bay in the flow of fresh air from outside, then wouldnt you want that side of the intakes free from obstruction? Or is that a bug shield of some sort? And also, with the intakes blocking/sucking air in front of the radiator, does that effect it's efficiency at all? Less air going through = less heat transfer?

it's a shield for rain......if you think about it, air is coming from the same place....both are equally same temp around...so i dunno

Guess that works too.. Since its a dry filter = sponge...

I'm no engineer, or even a gearhead, so I could be way out of line, but:
If they actually provide the same horse as the g3, it's not because it's getting cooler air from down below like the G3, it's getting it by sucking more air. So we would have to ask ourselves why it's sucking more air, which could be the angles or size of the pipes, the surface area of the filter (less likely), or the filtration rate. I don't believe it's the first two, so my thoughts go to filtration. Less filtration = increased air intake. Unfortunately, that also means more junk into your engine.

K&N for example claims to be 99% as efficient as a stock filter. While 1% doesn't sound like jack shit, over the life of a 150K mile car, that could be HUGE.

i dunno whether to get or not..........the dyno shown the the r2c site is crap gain in torque

I was wondering the exact same thing. I really don't like the idea of having a good portion of the radiator blocked, especially with some engines prone to overheating.

I really like the looks of this one a lot better. Does the G37 model fit our cars? It doesn't say on their website. And how much is it?

the 370z has it's own model number for the stillen's

the g37 front grille is higher than the 370z


or are you talking about the r2C's??

Average person keeps a car 8 years, would you hit 150k in that time frame?

i dont like the idea of oiling the filters

I don't like the look of the Stillens. I am interested in the R2Cs.

Me either, I've had several that needed to be cleaned and occasionally I'd put too much oil on there and foul the MAF.

Does this cover(circled) serve any purpose or function?

i would assume they fit because the engine bay is exactly the same


from the radiator the the firewall, it's the same.

radiator to bumper is different, which is why the Stillen Gen 3 arent the same model# for both cars.

nogood, have you seen the price?

no, why lol

it's an engine cover..... :roflpuke2:

yes, it is 410 shipped the canada.........i just got the PM from the vendor

It looks good when you pop the hood!

i will PM the guy to see if it will fit on the 370z if you want


it's a group buy price.............i'll asked for priced shipped to which zip?? PM me with ur zip code if u want

Are they a sponsor here? I sent them an e-mail.

it's the kyle(houston) guy

he will include anyone on the group buy over at myg37

No, but probably over 100K. Still a lot

i'll send a PM

I'm curious about the R2C filters, I'd have to see them up close to offer an educated opinion. As for the intakes, I like the way they look.

But I agree, I hated oiling the filter I had in my Jeep. In the summer months I checked it regularly due to the dusty roads and driving conditions I would put it through when I lived in Michigan. I had 2 filters so I wouldn't be out of comision when I had to clean and oil one.

Okay well let's see if they have fit one on a Z.
