Ordered the PowerFlow Intake and heater grid delete from Glacier; it arrived today. Installation was idiot-proof (my mechanical skills are roughly equal to a flat-head screwdriver)
//Shout-out to Richard...his cust. srvc is legendary...I emailed him 1/2 dozen times and he replied nearly as fast as texting.

I considered the CMF+, but opted for Glacier's due to cost and ratings were very comparable. (did I say Richard has great customer service?)

Attempting to load some before & after pics. Also loading a pic showing the clearly overly-constricted opening of the stock intake compared to the PowerFlow.

Pics should speak for themselves.

Install is only 2hrs old, so I don't have any performance comparisons...yet.

 

not sure how to load pics...?

 

 

..sorry..they're huge!....

 

WOW HUGE difference. This is good information. I just purchased an 07 RWD 3500 MC and engine is all stock, lookin to make some upgrades but nothing major.
