Had a custom intake fabricated for my RCF.
had this made while I was on vacation in August.. dropped my car at a local speed shop and they fabricated this for me, this is stage one there will bee
car was data logged during the fabrication both on the factory and on this intake, results show a 15° temp decrease with this design.
haven't had a chance to put it on a dyno yet want to get my exhaust in place first.
The fabricator is not (yet) a forum vendor so I will not post any details about them or the pricing. you can PM me and I can direct you to them, but I don't want to run afoul of the forum admins publicly posting until they have setup their vendor status.

yes, that unit is built into the factory air box.
if you look at my image you will see the vacuum line capped off with an orange cap. essentially it is like doing the solenoid disconnect mod allowing the secondary air door to remain open at all rpm levels, the only purpose for it is noise reduction.
for purposes of warranty work swapping back in the factory intake takes about 10 minutes. everything is basically plug and play with the exception of having to unscrew the MAF sensor from the aftermarket intake and reattaching it to the factory air box.

hope it doesn't eliminate the noise made when stock secondary intake opens up

since the stock air box is completely removed that 'sound' happens across the rpm band now, not only above 3,700 rpm. however the sound is minimal until you go WOT.

I doubt very seriously he'll have any difference in the dyno numbers, this is just to let your car breathe a lil' better & it also makes your engine look a lil' better! You probably saved about $500 from what i spent & your's serves the same purpose, but i think mine looks Better & i probably saved an ounce or two because of the titanium!

this is basically a "proto type" if you will, there will be some further tweaks to it, smoothing out of the welds, make a different color (maybe blue to match the intake manifold), this was a first run, the guys that fabricated it up want to put together a kit for the RCF so they will be making their molds and such from the design. As I said I don't want to get to much into that aspect of it because they are not vendors on this forum yet, I know they are in talks with the admins about it, so I can't really give too much information publicly.
just throwing it out there as another option, these guys are top notch in what they do, intakes, headers, exhaust, etc. for all makes and models, from a 1963 Stingray to a 2016 Chevy 3500 HD diesel dully. from a 1971 Skyline (I think that was the year they had sitting in the shop might have been a 1972) to a 2015 GT-R, and everything in between Toyota, Nissan, Chevy, Ford, VW, Audi, Etc.

yes you can hear it across the rpm range. It's mild at low speeds but you can tell it's there. I've seen a few heads turn in opposing traffic when I've made a right or left turn and opened it up, no one expects that sound from a Lexus.
