OK...I maybe the only one out there who is experiencing this issue…but I would like to hear from everyone…
For those of you out there who have installed an aftermarket CAI I want to know if you are experiencing the exhaust leak / ping noise that I am having resonate through my aftermarket CAI. I currently have a K&N 77 series intake. It is my understanding that most 05-08’s with an aluminum tube CAI will experience this.
There are two fixes that I am aware of…first being disconnect EGR valve but live with a check engine light…and possible engine damage. Second being purchase a EGR Valve Baffle…which I am unsure of its long term effects….or you could just live with it…and hope that at some point our buddies at Mopar will come up with a fix….
Please post what CAI your truck is sporting

 

I have no ping......K&N FIPK Intake, its a plastic tube I dont know how much of a diff that would make...

 

It is my understanding that the plastic CAI's absorb the noise...hopefully someone who has more knowledge of this issue will verify...

 

ok that makes sense.......anyone going to fill us in on this?

 

I have an 04 4.7 w/ a custom made aluminum intake. No ping, but it does "gasp" as some on here put it, thats the reason I put other. Unfortunatly, I'm not one of the "educated" ones who'll be able to tell you about your specific problem. Good luck

 

I do not have an intake but this issue has been addressed before. Those with the metal intake tubes are much louder than the plastic ones. I have got no idea why but I have heard this many times. Hope this helps....

 

Using the AFE High Breather set-up; excellent quality and performance but does not perform the miracles that other CAI's"seem" to claim.
The benefit of not having ANYuseless additional noise was an aspect that I appreciated with this choice and I've been usingit successfully since 11/06'.
The stock Hemi airintakesystem is really quite good for mostpeople but we all like the freedom to experiment and choose where we want tospend our $$$'s!

Happy New Year***

They all amplify the EGR to some degree, you just usually don't hear it over the exhaust with the plastic tubes. I have the K&N 77Series as well, and yes that nice shiny steel tube amplifies the hell out of the EGR. The addition of LT Headers kinda makes it a little harder to hear now though...

 

I've gotclatter/rattle but mine's completely stock...no it's not the hemi tick. I have no idea where it's coming from...could be the EGR I guess
