So, I started with an aFe CAI to improve air flow and drop intake air temps. I noted the improved air flow through the "seat-of-the-pants" method, but according to SGII data, the temp drop from stock CAI to aFe was minimal. I consistently registered intake temps 12-15 degrees above ambient with the aFe.
I then installed a TRD S/C and was really happy with the whole set up, but was still disappointed with the intake temps.
When I installed the snorkel I noticed a dramatic difference. Intake temperatures were consistently 0-3 degrees above ambient. I decided to seal the aFe CAI to take full advantage of the snorkel if necessary, but during my first torrential downpour on the highway noticed the motor coughing. After a little diagnosis, I unsealed the air box and found 1/2 inch of water pooled in the bottom, getting sucked in through the snorkel and then the ProDryS conical filter. I drained the air box, installed a clean, dry filter ProGuard7 filter and swiveled the snorkel intake to the rear. All good for the remainder of the trip.
Since I wasn't comfortable with the way the aFe sealed air box and conical filter so readily sucked in moisture with the S/C (I could hear it from inside the cabin... cool ) I put the stock CAI back in and sealed it. The intake temps over ambient are still consistently 0-3 degrees, but does heat up more readily at idle. The "seat-of-the-pants" has noticed a little difference, but it's negligible considering the weight I carry around (although it is significantly different when stripped down...:silly I have yet to see how it does in a downpour, but I expect the convoluted tubing to cut down on the S/C vacuum potential.
