Nice write up and another way to get air into our gen3

NICE i am going to try this on my G37

Just did this finally! Thanks for the write up :tup: it was tough getting the bumper back on with the big oil cooler lines and the ducting on the passenger side but if you push hard enough, anything will fit lol. I'll report on intake air temps, I've been watching them without the ducting so I'm interested to see if the difference is major.

UPDATE:

After going for a cruise and monitoring the new intake air temps, I can confidently say that the ducting for the G3's does work. It is 18 degrees Celcius here today, and after everything was warmed up (oil at 90 degrees, coolant at 83) while idling the intake air temp was around 38-40 degrees Celcius. As soon as I started driving again I could watch it dropping to around 27 degrees, and once moving faster 23 degrees Celcius. That's about where it stayed with Highway driving, 4-5 degrees C hotter than the ambient air temp.
This is a reduction of about 5 degrees from before I had the ducts. (I would see about 28C as the low temp on the hwy given the same ambient temperature) It'll be interesting to see come next summer how close to ambient air temp the IAT stays as I used to see intake temps of 58C when it was 28C outside

Just curious, does anyone run, or have thought about running the Varis or Mines air ducts, for this purpose?

I think they would work and be helpful for getting more/colder air to the G3's. The tradeoff is they'll also dump driving rain into your G3's (if you drive in the rain on the street). That and they're kind of expensive for little plastic edge-pieces. It would be cheaper to fab up your own or buy something generic that has the same basic shape.

Also, both of them as installed in the pics above are too far apart. Even the narrower Varis layout would be at the rear edges of the cones. It would help, but it would be more ideal to have the inlets closer to the center.

My friend (no longer on this forum) did that with some off brand ducts, he offset them so rain wouldn't hit the filters. Honestly, I think it looks REALLY bad...

Sorry... Um... I forgot the member that I think has these on his car, lol

do those 2 black pieces (where you put those pipe ducts) screwed on or clipped to the bumper or do I have to cut it out?

I’m gonna post on this old thread & see how others have introduced more air to their CAI’s.
Here’s my air guide I built to direct it through radiator & wraps around to filters....currently all foam is in place;but thinking of removing section in front of filters or either piping in from fangs.
