"The AEM Brute Force Air Intake System was for the most part a good buy. It added a nice sound to my TJ and a little much needed power in third and fourth gears. But the only negative thing I can say about this product is that it did not add any "passing power" to my jeep in fifth gear on the highway." —Mitch B from Louisburg, KS bought an AEM Brute Force Air Intakes for a 1998 Jeep Wrangler.
"Recently I had the pleasure of meeting a fellow Jeep enthusiast; who suggested I purchase and install an AEM Brute Force cold air intake on my 1998 Jeep TJ. I'm not the type to just get online a buy the first one I find. AutoAnything.com made this task extremely simple. they had the best price out there. I was very impressed with the shipping time and the email communications. The evening I found the package on my front porch was the evening I installed it. Installation was a cinch, great instructions (written & illustrated), and most of all. all the parts I needed were in the kit. About an hour later, I was out of the garage on a road test. The first thing I noticed was the increase in power. Definitely gave my TJ a zip. Now as far as gas mileage. I'm trying to maintain my discipline on this second tank of fuel since the install. The first tank of fuel I didn't even bother to compute due to the fact I was too fascinated with the unique roar of the intake when I'd stomp the 4.0 to the floor, just awesome. If I maintain the gas mileage I had before I'd honestly be thrilled. The increase in horsepower, the impact it has on my engine appearance and the impressive tone makes it all worthwhile to me. I would absolutely suggest this particular kit to fellow passionate Jeep enthusiasts." —Jim W from Huntsville, AL bought an AEM Brute Force Air Intakes for a 1998 Jeep Wrangler, 4.0L 6 cyl. engine.
"Not only is better then the stock air intake but looks better too........ when adding oil after a change the filler is easier to get to also. Before you would have to reach over the stock intake tube and try and not spill. Now you have a clear shot with no obstructions.........All the holes lined up too. Very happy with overall product Thank You!" —Paul B. E from Lake Elsinore, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1998 Jeep Wrangler, 4.0L 6-cyl. engine.
"Eliminated some of the clutter under the hood. Looks very clean and seems to work fine. I expect the filter to be easy to clean and reuse." —Mike W from Boise, ID bought a Spectre Cold Air Intake for a 1998 Jeep Wrangler, 2.5L 4-cyl. engine.
"I am really impressed by the banks ram air for my jeep. This thing is a monster compared to my stock box and intake tube. Banks states they have the biggest intake tubing on the market and they were not lying. I noticed a big gain in power from it, but I am also running a banks header, magnaflow high flow cat, flowmaster 40 muff. Im really happy with it and glad i went with banks over other brands." —Kevin H from Wichita, KS bought a Banks Ram-Air Intake for a 1998 Jeep Wrangler, 4.0L 6-cyl. engine.
