So I got my mopar performance air cleaner in today and got it on. Does everyone have that whistle sound? I think it went away mostly after it got warmed up but not too sure. Also I think mpg in town maybe a lot better but don't know yet. Took it out on the interstate and ran 70 and heads up display said i was getting like 10-11 which is what I usually get so idk. Maybe bad o2 sensor? It was a little wet in thottle body so prb plenum gasket? Could that make really bad gas milage. I was getting 8 in town and 12-14 interstate. Also I just reset pcm, so we'll see if that makes it any better. Should resetting pcm clear heads up display and stuff ?? Cus it didn't

 

yea i have that same whistle sound, it the throttle body

 

Yup, that is one of the downsides of the round air filter. It is noisier then the stock air assembly. But that is the trade-off you make to have a better flowing air cleaner.

Lets see some pics.

 

tomorrow for pics!!
