Custom Cold Air Intake

Looking nice. So that plumbing is all just ahead of the factory airbox? What did you do about the MAF housing? I'm quite willing to work with someone to design a MAF housing for the Micra.

I will be replacing the entire system from the throttle body. The second diagram is the most accurate example of what it will look like.

Everything I'm going to be installing behind the inline filter are just random off the shelf pieces. I was hunting for a long time for a solution for the MAF. Everything is so expensive!

I just sucked it up and ordered a MAF mount and attached tubing (2.48" OD) from China and will have to wait a few weeks til it gets here. Silicone couplers aren't cheap either so it will at least give me time to source out a few of those for a reasonable price.

Here is the piece I ordered: http://www.ebay.ca/itm/2-48-Inch-OD-...19.m1438.l2650

Here are the other options I was considering:
1. Flange adapter: http://www.ebay.ca/itm/261372030660
2. Adapter with tubing: http://www.ebay.ca/itm/2-5-OD-Slot-S...0AAOSwMmBV5Hrs

Here are the pieces I have so far:


I know it's super ugly but it should flow well when the setup is complete. It was my first time ever working with fiberglass/resin and in an effort to cut costs I only used the stronger but messier stage 2 glass cloth. I might slap some more coats of bondo and paint on the top visible portion to "purdy it up". If I already had any fiberglass tools/material on hand it would have been much cheaper and I probably would have staged two different layers of cloth.



Luckily even with stage 2 glass cloth it turned out quite smooth inside where it was against the wax/tape & mold.







The last few things to order are:
1.) 3.25" to 3" reducer
2.) 3" to 2.5" 90 degree reducer
3.) 2.5" to 2.5" coupler
4.) Vac hose and adapter
