In JP magazines April 08 issue. They test 10 different CAI units and dyno test the results compared to stock. Almost every CAI actually added 10 hp and 10ft pounds of torque over stock.
When I started shopping for CAI's I thought it would be a good idea to leave the option open to add a snorkle down the line. Volant is the only one that makes an enclosed air box on their CAI so you can attach a snorkle later.
If you don't like the look of the Volant snorkle it would be pretty easy to hook up ARB's instead.
The kit installed in about 15 minutes and used the old airboxes bolt holes through the fender. The air box, filter element and ducting are all way bigger than stock.
Is there more power? Not until you go over 2,000 rpm and are really heavy on the skinny pedal. Also when you floor it there is more engine noise, but in a good way. Like a custom exhaust has been installed.
I like driving fast and appreciate feeling a little more power during acceleration. I also tested it going up hills that I am used to driving and the jeep didn't need to downshift as much.
Below 2,000 rpm and under normal driving conditions there really isn't any difference.
Mine cost just under $300 so its on par or cheaper than the other brands. All in all it works and I would recommend it!
I have the Volant CAI & Snorkel installed in separate occasions. If you liked the Volant CAI, you will love it with the snorkel.
I have the same feedback as yours, but with the snorkel, it's even better.
I've been monitoring the IAT via my ScanGuage vs the ambient temp via the auto dimming mirror. I've got the horn removed on the stock airbox. So far the past 2 weeks, the highest temp I've seen out of the IAT has been around 80*F - with an ambient temp of about 50*F, and that was when idling at a long stop light. The faster the vehicle travels, the colder the IAT gets - even down to 30*F on the highway when its ~15*F outside. So far on the street the actual intake temp seems to run at twice the ambient at the hottest while idling. As soon as you start moving it drops.
I installed my Scan Gauge after installing my Volant CAI. The Volant CAI still sucks hot air from under the hood as a divider to block engine heat from the intake is not included in the kit (but can be easily made) and the intake in still under the hood.
The outside air temp in where I live is constantly 90-deg during the day. With the Volant CAI, start-up temp, as shown on Scan Gauge's IAT reading, shows on average 135-deg. and warmed-up engine is usually around 180-deg. With the snorkel, start-up temp is at 90-deg. with warmed-up temp average at 120-deg.
Just posting this as a contribution for everyone's reference based on my experience.
