Woohoo, glad to see everything fit up great and that its working with no CEL. Thanks for testing Spacewolf!

As for the splitting issue, that should be an easy fix. In order to keep the print...

Spacewolf has agreed to test out the MAF housing on his up and coming CAI setup! For this he gets a free MAF housing. Thanks Spacewolf!

I just assembled it this morning. Fit up still isn't where I'd like it to be, but that doesn't stop them from working, its just an assembly thing. I really just need someone to test it out now,...

I just started printing the new version of the MAF housing. This time it'll finish in about 5.5 hours. Not nearly as bad as 7!

Yes, it should fit quite well. The OEM housing is 62.5mm in diameter which is 2.46". With a clamp, it'll cinch down very nicely.

I worked on version 2. It eliminates some excess material, makes it look a little prettier IMO. It should also reduce printing time, reduce material use, and therefore also reduce the cost to make...

Thanks guys! Its been a fun project thus far.

I may need some help testing out the product since I do not have a Micra handy to throw one on. This would involve working with me a bit, taking...

Yep, its printed in two separate pieces that come together. The fit was not good and I had to shave some material off each piece to get it to fit together nicely.

The parts are now off the 3d printer! Phew it takes a while to print this thing, 7 hours. I'll be attempting to tweak that with subsequent runs. It also didn't fit up very nicely at all, so I'll...

That is a good question. I'm not 100% sure yet. I still have to get parts 3d printed and see how long it takes to do so. That'll help determine cost.

Thanks spacewolf. I appreciate you willingness to help out.

I've continued the development. Using a digital caliper for accuracy, I measured up and then modeled the MAF housing. I'm a...

Ah, gotcha.

This piece goes right where the airbox used to go. The MAF sensor stays exactly where it is in the OEM setup. So you would plug the MAF housing into the rubber piece right off the...

The MAF housing has to be OEM sized. If it isn't, it throws off the MAF readings and you'll probably get a CEL. Upstream of the housing you can change to whatever size tubing you would like.

Its been mentioned a few times on the forum, but I've been wanting to develop a part for our Micras. I'm starting this thread to show the development process because I think its fun and interesting....
