Mass Air Flow Adapter Pipe for Coyote Gen 2

[tbl100]

This part has been on back order for almost a year. FF has given me several dates at which it was supposed to be available. The latest being mid Dec. 2019. Still no part.

16403 - Mass Air Flow Adapter Pipe

I'm hoping to be starting my engine within the next few weeks and need to come up with an alternate solution for this part since it doesn't look like FF is going to come through anytime soon.

I'm using an Gen 2 Coyote with FF supplied Silicon 90 degree intake (see photo) and FF supplied air filter. Any suggestions on what to use?

Thanks again,
Tim

p.s. - I'm not opposed to scrapping everything FF supplied (or hasn't supplied) and going with a complete new cold air intake provided it doesn't require a special tune. Looking at all my options. thanks.

Not sure if the Housing is all you need.

Here's what I used.

From Summit
SPE-9741 - Coupler 3.5" to 4.0"
SPE-9771 - Coupler 4"
SPE-9799 4" 90 degree
SPE-9705 - MAF Sensor Housing
K&N-RU-2520 Air Filter

From JLT Performance. Would have to look up parts numbers, if you go this route.
PCV & CMCV Fittings

I have the same exact Spectre parts Ducky2009 lists on my 20th Anniversary Roadster. Those are the ones listed on the Factory Five Gen 2 Coyote instructions. All are available for immediate shipment at Summit and probably elsewhere. I didn't use that particular air filter. Plus I see it's not readily available right now. I used a K&N RC-5149, which is available. Slightly longer but it fits. If you have a newer Gen 2 (2016+) you won't need the JLT CMCV connector to the intake. They've vented to the atmosphere and you don't need to do anything except hook up the vacuum. You will need the JLT PCV connection however. Not sure what Factory Five is supplying. Maybe that part is in their completion kit.

Won't need a custom tune? Basically any time you change the stock cold air intake to anything from stock the MAF calibration is going to be off. Your Gen 2 will start and run OK with the stock tune. But it will run a lot better with a custom tune. Lots of us have gone through that.

Thank you for the parts list. I'll look up all this. Really nice to know what people are using and what works.

From what I can tell my engine was produced in 2017 even though I got it from FF in 2019. I'll check on all the parts and more than likely will need more info on the vacuum connections. If I need a custom tune then so be it. I;ll need to figure out where to get that done. Thank you for the feedback.

Production of the Gen 2 Coyote ended in 2017. Almost for sure that's the latest version and you don't need the CMCV connection to the intake. You should find only one hose from the back of the engine through the intake to the front. That's the one that needs to be attached to a vacuum source.

Ok thank you.

So in looking at the parts you and Ducky2009 used there are no vacuum ports on the 90 degree tube. By CMCV connection are you referring to this connection (see photo) If not connected to the intake what do I do with the open port? Some sort of valve cover breather filter or something?

This is a photo of the hose (blue tape covering the opening) that needs the vacuum connection. Where is the best place to find a vacuum source for this connection?

I found the post where you described the CMCV system and its function. Very nice write up.

It probably would be simpler to find a MAS adapter tube to add to the existing parts FF supplied but now I think that grey 90 silicon tube they supplied is kinda ugly. LOL

Thank you again for your support.

That intake tube you have has two connections. Neither are vacuum ports. The large one on the left side is for the PCV hose from the LH head. The hose in your picture attaches to it. The one on the right side is the vent for the old style CMCV vent which your newer engine does not have. You need to cap it.

Much has been written about the CMCV vacuum connection. If you don't plumb it properly (1) the system won't work and (2) your engine will throw DTC's (error codes). Unfortunately the subject is not addressed in either the Factory Five or Ford Performance instructions. Something I don't understand. Very simply, the hose circled in green below (the one with blue tape in your second picture) goes to the vacuum port with the red arrow in the second picture below. FYI, the hose circled in red is the one your version of the engine doesn't have. And the one circled in blue is not included with the crate engine (nor should it be) but shows how the vacuum port in the Mustang is used to power the CMCV circuit as well as the power brakes.

Thank you. I think it's finally starting to make sense to me. I sincerely appreciate the help.
