Help R2C Intake Installation
R2C Intake Installation
So I'm about to install my R2Cs.
I already have them all assembled, now it's just a matter of taking the stock air boxes out and putting these in.
Looking through all the screws and pieces, I noticed that there are two plastic pieces that I don't know what they are for, and the instructions don't show where they are used. One is a Y shaped piece, and the other is an L piece. Anyone know what they are for?
Also for installing them onto the throttle body, did you guys install the coupler onto the TB and then put the tube on, or put the coupler on the tube, and then attach to the TB?
Any other install advice is appreciated. Thanks!

The L piece should be a metal L bracket, which is used to support the filter assembly.
It goes on the same mount that the stock box bolt to nest to the fenders.
The Y shaped?? I dont have that, can you post a picture???
Slide the coupler on and lightly tighten the clamp, then the tube. Finish tightening when all is mounted.
Meaning loosely mount every piece then tighten everything while lining up.
Make sure the passenger side air shield does not rub on the upper radiator hose, and the power steering hose.
Theres a DYI here somewhere that shows you how to route the PCV vent hoses more easily.

no, it's definitely a plastic piece. I'm in the middle of the intake installation now, but i can't figure out how to route the hoses on the driver side area that come off the side. i'm looking through a DIY to see how others did it. i'll post the pics of those pieces afterwords.
the L and Y fittings are for the breather lines. On the 07-08 sedans, those pieces are needed to get the breather hose from the intake tube to the air resonator chamber (black plastic boxes) on both sides. if you dont need them, you dont need them. Some do.
So were all guessing until he show us pics!!!

I just installed the R2Cs yesterday... I have 07-08 G35 sedan. Our engines only have 1 crankcase valve (on the driver side). The G37 have 2 crankcase valves... so the tubings are different. bat6wc is correct. The Y hose connector is for the driver side and the "L" aka the 90 degree hose connector is for the passenger side. This is only applicable to the G35.
As to the 2nd question... I installed the coupler on the tube first, then when I was ready pushed the coupler onto the TB.
The only other thing I'd like to point out is to make the "L-shaped" bracket (the one that connects the heatshield to the car frame) face up. ie. the nut/washer is above L. That way, you can force the intakes up higher to better shield against heatsoak.

Hey guys, so I got them installed.
Yeah, they aren't the resonators, they were pieces that came with the intake, and like bat6wc mentioned, they are the fittings for the sedan. I didn't end up needing them.
I did have some trouble on the driver's side installing the tube. The extra hoses that came weren't long enough so I just used what was there stock, and looking at another install just moved the tube that connected to the engine a little bit off and that helped fit right up.
I will eventually check to ensure that there is a seal on the hood liner, but I didn't bother with that yet. Everything else was pretty good.
I took it out for a quick spin, and let me tell you, it completely changes the sound of the car when you get on it. COMPLETELY. It is this deep growl, and I love it. Driving normally, you'd be hard pressed to tell a different from stock. I'm enjoying that aspect.
I read that others said the tubes stay cool during driving, but I did notice that the tubes were pretty hot to the touch. They weren't burn my hand off hot, but I wouldn't want to keep my hand on it for an extended period of time. The temps right now are in the mid 60s, so it's not a super hot day or anything. Is this normal? Only reason I ask is because others said that the tubes stay cool to the touch.
Other than that I am loving it. Attached is a picture of the final step.

Woo nice!
Who said they're tubes weren't hot? Mine are pretty darn hot...
My FILTERS were hot after spirited driving until I re-aligned the heatshields to touch the hood liner. Now they arent hot... but the tubes still are...

I just did the baby powder test, and my right side one was barely touching. I had to twist it quite a bit, and put some washers to where it connected to the fender to raise it up a bit, but now I can get the powder to transfer to the top hood liner. So it's all good.
I'm just worried about the hose on the driver's side. I have this fear that it will pop off on one side while driving. If it does, what's the worst that would happen?

Alright, another update.
So after I drove home from work, I decided to check on that hose, and as I had feared, it had come off. Not completely off, but I could see the hose barely on the tube it was supposed to be connected to.
So to remedy this, I took the two short tubes that came with the Intake, as well as that L bracket, cut both hoses down a bit, and stick it on. I wasn't able to put the fasteners on, but it's definitely a secure fit.
The issue I noticed this morning when driving it, is that there is a vibration when moving from a stop. It's probably from about 900-1500 rpm, and after that either the engine is too loud for me to hear it, or it stops. I'm fairly certain that it is coming from that L bracket hitting some part of the engine, but I can't be certain. I will be checking it when I get home from work. I may use some of the cut up hose I have and zip tie it to the L bracket on the side where it's touching the engine. That should eliminate the noise. Hopefully it's nothing more serious.
Any thoughts?

You need to secure the PCV hoses with the supplied clamps.
The vibration are the R2C shields aganist the hood.
