Part #311-212, SynthaMax Dry Air Filter
Fits 2011 - 2014 Jeep Grand Cherokee (or Dodge Durango) 5.7L and 3.6L
Bought at Amazon.com for $185.04 w/free shipping
This installation was for my 2014 GC with the 3.6L
I chose the Airaid CAI because I wanted to keep the stock plastic
intake (less heat transfer than an aftermarket metal tube), didn't want to deal with an oiled filter, low cost of product, and I did not want to modify the engine cover to fit some of the other brands of CAI's out there...including the Mopar CAI.
Here's what's included in the kit (hose is for 5.7L only, did not use)...
Total Time - 45 minutes, very easy for the average person to do
Tools Needed: 4mm Allen Wrench, 8mm and 13mm sockets
Instructions were excellent, very easy to follow with nice pictures...no suprises. Here is a picture of the stock V6 airbox removed:
Here's a picture with just the Airaid heat shield & stock air intake installed:
And here's a picture of the completed project:
Weather: 50 to 75 degrees, combination of city & highway driving (mostly driving back & forth to work like usual, bumper to bumper on the highway at times), "ECO" mode on 100% of the time.
After a full week of having this installed, I have to say I'm very pleased. Can't say that I feel the extra 10 hp / 12 lbft the manufacturer states this CAI gives you (from dyno charts), but I can say that not only is the engine more responsive, I have observed an average 0.7 increase
in gas mileage (up from the 0.4 mpg I saw using the aFe dry drop-in air filter instead of the stock filter)...20.9 mpg on average! Engine noise is slightly elevated at WOT, but at idle or just tooling around town you wouldn't even know you have it installed. I've installed other CAI's on my other vehicles in the past...some caused issues like MAF scatter or the engine/transmission to act funny, but I'm happy to report that NO
issues like these were noticable!
