I installed the intake on my 2021 3.5 Ecoboost today and wanted to know what the CCV tube insert does?

I just installed my S&B yesterday, but from my understanding of the instructions, the CCV tube was only for the 2022 2.7L; not the 3.5. So I didn't install it.

That's what I thought at first, but step 20E (image 2) shows a 3.5 engine.

I found this in another forum which I think answers my question:

I imagine you’re probably getting a P04DB.

That is from the intake effecting the amount of vacuum the CCV sensor is designed to see. You can pick up a tube insert that supposedly fixes that code.

Well, I could never tell that was a 3.5 from the photo. I didn't install mine so I guess if I start throwing error codes I'll install it.

My Roush intake didn't come with it for my 21, but my AFE intake on on my 2016 did. Without it, it would throw a code.

Just installed the S&B 75-5122 on my 3.5 today, I didn't have the tube in the box nor did I install it. Maybe they were just using the image of the 3.5 for the cover description to put the cover back on. I haven't driven enough to know if a code will come on yet.

I was installing this on my 2.7 tonight. Came to the steps of rerouting the vent hose and orienting the cab tube insert and thought I’d do some research first. Previously I’ve never done this on older models.

Anyone else install on a 2.7? Did you complete these steps?

Those of you above with 3.5, any error codes?.

So other than throwing a code, is there any possible issues that could arise from not installing the tube? Specifically for reliability?

I've been running the intake now for 9 months without installing the tube on my 2021 3.5 Ecoboost and never had a code.

I know this is late as crap, but the good news in all this time I have not thrown a code since the install. I added MBRP cat back 4" a week later and have been fine with it as well.

So I just installed mine today. I have a whining noise now. I hear most from the drivers side. Any ideas? I have a 3.5 didn't install the tube either.

Put about 10 miles and no CEL.

I have a 2022 3.5 and put this intake in and i didn't put the tube in because what the online instruction said to get at O'reilly's was not correct. I have had no codes or issues and on day 4 after installing. Glad i found this site and thread!😎👍
