Update on this. Emailed AEV with a video of the sound from the pre filter, then sent me a new one right away. 10/10
Same here no issues with the truck, no pcm updates.
I was wondering what the life was on those and if they were serviceable...?
That’s because it’s creating a restriction in the intake so the CCV sees normal vaccum. Not a good thing and losing any benefits of having a cold air intake in these.
It's still pulling cold air and ejecting dust/debris before the filter, so I'm not sure what you're talking about.
If there was a significant restriction it would also throw a code. These trucks are extremely sensitive to airflow. My truck runs at least as well with the snorkel and cyclone. I’m stock under the hood. I have mixed feeling about the cyclone’s noise. Cruising up the Blue Ridge Parkway or up Warbler Road it’s a bit annoying because I can’t hear the birds. You have to be going fast enough to spool up the cyclone but slow enough that you’re not getting a lot of tire whine for it to be an issue. That’s a pretty narrow band and otherwise it doesn’t bother me. Around town it doesn’t matter; same on the interstate. With the widow rolled up I can’t really hear it. I’m not sure how long the bearings last but the whole thing is pretty simple. There’s no real restriction in the cyclone. It’s not another filter. It just has a narrow bar that creates a vortex and kicks the dirt to the outside out of a slit in the casing. I’m happy with mine.
Yes theres a company with our engine's name of canada on FB that solves these issues.
The reason they throw a ccv/pcv code is less vaccum on the sensor with an aftermarket air intake. The prefilter/cyclone is causing a restriction which means more vaccum on your sensor. Atleast equivalent to factory. Its a snorkel so you get the high intake and water protection but your not going to see faster spool up, MPG, or improved anything else. Remember the pcv/ccv sensor measures "vaccum" looking for a leak or failure of its system. This is entirely emissions driven. More vaccum in your intake more suction on the pcv/ccv which can be good for ring seal and crankcase ventilation but that also means your turbo is not getting any additional air beyond factory.
Myself and I think everybody else is aware of all of this, as it has been discussed at, I'd say, considerable length in this thread.
Correct, mine is just hooked up to my stock air box. No codes, no issues, and I’d even hazard to say that it’s helped keep my oil temps down on long drives. Haven’t really changed anything else different since the snorkel, so don’t know what else to attribute it to.
