Cold Air Intake / 2016-2019 CX-9, same engine bay?

:
South Florida

2016 GT
Hi all,

Does anyone know if the OEM air box (or mounting positions) changed between the 2016 and 2018+ models?

I have the 2016 FWD GT, and I’d love to get more blow off (BPV?) noise from the intake, however I’m worried about engine temps and water getting into the system as I live in hot 100+ degrees and rainy/hurricane prone South Florida. Anyone in hot climates use the Corksport short ram? Any problems?
I know corksport claims the SRI is far enough away that temperature is not an issue but I’m skeptical in extreme heat environments.

Has anyone tried these?: https://www.knfilters.com/69-6034ts...MIvOrNt8Op6QIVAobICh3D8QDdEAQYASABEgJk2vD_BwE
Or
good results?
They are only listed as compatible with 2018+. So did the engine bay or mounting points change from the 2016&2017models?

Thanks in advance and loving this community/forum thus far!

Everything should be the same. Mazda hasn't changed anything structurally and won't until there is a 3rd gen. Also everything in the 2018+ Mazda 6 engine bay is also the same. When Cork Sport was coming out with their SRI I took some measurements between my 2016 CX-9 and the 2018 Mazda 6 and everything is identical. I am not sure why AEM and K&N don't list 2016-2017 since they are the same.

After looking at a Mazda parts website for about 2 minutes, it appears that the part numbers for the intake tubes, housings, and MAF are the same from 2016 through the present. I'd guess it will work without issue.

Of course, I'd call corksport or k&n and ask before I bought anything.

I would like to know anyones opinion of the AEM intake once they installed it. I like the fact that it is true cold air intake with a sealed air box. I have a Cork Sport SRI Which does have some improvement but I don't like the fact that it does pull warm air and makes some noises from time to time since there is no air box. Both AEM and K&N use the tube that pulls from the outside. I am curious to know if anyone knows what the CFM rate is for the cold air tube is. Mazda has always used a flattened out intake tube somewhere in the system before the turbo.

I would also be interested if anyone could report on the performance with the AEM intake.

IMO, both versions won't offer a significant improvement over the CorkSport. The K&N version looks like it reuses the OEM "snorkel", but not in a meaningful way since the "box" has no top/lid, thus the intake draws ambient air in over the battery and from the lower bumper area. In essence, it would basically be doing the same thing that the CorkSport intake is doing. With the AEM, you have more of a "box" that also encloses the intake tube, using the OEM snorkel to draw air in from the area in front of the radiator, but the opening in the box near the headlight/lower bumper is quite large, so the majority of the air drawn in wouldn't be from the snorkel anyway.

I'd want to know if the extra materials are worth the $100 extra for the K&N or $136 for the AEM.
 
I am not sure how much gain would get when reusing the OEM cold air intake. The air path from the OEM air intake is very restricted, I don’t think any improvement “behind it” would account to much.

i am talking specificically at the air path in front of the snorkel. That area is all sealed off with the exception of the holes surrounding the latch in the center. unless I am missing something but this has puzzled me a bit for some time. I am surprised there is enough airflow to deliver the stock performance as it is.

Thanks for all your inputs!
I went ahead and ordered the Corksport. Like Sm1ke said- all of the boxes are open and taking in warmer air anyways. I was told by Zach @ Cork; “We do have a isolator for the intake coming out really soon!
I don't have an exact eta, but they are in production.” Production confirmed, hopefully its available before mid summer.

Have any of you guys done the Cork axle back exhaust? I think Chris may have. Was install as straight forward as it looks? A couple jack stands and wrenches can get it done without issue it seems. Anyone experience leaks or other issues?
Any other recommendations beside Cork? I don’t have the AWD model so the cat back isn’t possible (and maybe too loud). Anyone replace the downpipe or blowoff/by pass valve? Is this even possible on the Skyactive?
Thanks again for any input, u guys kick ass!

Besides the CorkSport exhaust, there are a couple of members who did custom exhaust work, which I believe amounted to removing the rear mufflers and replacing them with only exhaust tips. Any muffler shop could also cut off the OEM mufflers and weld on a pair of aftermarket mufflers from Magnaflow or the like. Aside from that, I'm not aware of any other options.

I did do the Cork Sport axle back and I think it is perfect. I bought the first one out of the gate that was the turbo back. The turbo did spool faster but it was as loud as my 08 speed3 with a 3" turbo back. I still have the the mid-pipe which is brand new. If anyone does the axle back and decides they want the mid-pipe let me know.

I have the axelback Corksport exhaust installed and was thinking to complete it with the midpipe section. Speed3chris1 what was the reason you didn't also install it?

When I got my cat back one of the exhaust hangers wasn't positioned in the right spot. Cork Sport shipped me a new system but I didn't put the mid-pipe back on because it was too loud for the CX-9 I liked the performance when the Cork Sport mid-pipe on because the turbo spooled faster but when you increase the diameter to 3" the sound increases and it doesn't make a difference if you add a second resonator or not. So bottom line is I have a new mid pipe collecting dust.

Hey Chris- do you know if the mid pipe only fits the AWD models? How much are you looking to get for it?
