Brake Duct Inlets on OEM Bumper

fairladyATX · 11-26-2021, 01:36 PM

I just picked up the Z1 Brake cooling kit (it's $50 off right now BTW for Black Friday), but it doesn't come with air inlet plates.

Any advice on where to get the air inlet plates that'll work with a non-Nismo 2014 front bumper, and how to best route the ducting?

I think people have been using aluminum or plastic flanges of the correct diameter for the piping. I think the Z1 stuff is 2.5” so a 2.5” flange is what you’ll need. I picked up two off Amazon (used for vacuums I think) and should be good enough for warm temps. The aluminum ones used in the DIYs (http://www.the370z.com/diy-section-d...ur-airbox.html) are from an aircraft store. Most people place them at the fang vent opening (there is a little block off plate there). There will be some hole-making involved, so obviously do this at your own risk.

If you dig through my build thread. You will find pictures for routing the hoses.

Here is what I plan on using:
https://www.ebay.com/itm/14116778923...sAAOSw-Rlft97r

revotec inlet duct
63mm should be the right size for your ducting

There is also a filter on eBay for these ducts

Seems simple enough to mark and cut a round opening for these

The left side is easy, should have lots of room
Right side has the window washer fluid reservoir

If ur tracking u should probably have a vented hood and no longer need that reservoir, so once that’s gone I think routing is easy

Perfect, thank you! I just ordered the air inlets off of eBay, looks like they'll do the trick. Hoping I can fit them into the 'fang' area, if not, looks like I'll have to cut the bumper.

The washer fluid reservoir makes it interesting on the right side when routing the hose. The closer to the grill opening, the easier it is the route.
