Decided it was time to make way for the OBA and gathered everything up for a cowl intake. Iíve got Airaid cone filter, some exhaust pipe, Spectre flex tube, Black ABS
Tools I used Gloves, Pliers, phillips and standard screw drivers, sand paper, shop rag, drill, 3 ľ hole saw, knife, safety glasses, spray paint, wd40, socket and my strand of hose clamps.
Decided to mock everything up into place and started with the stock air filter flex tube. Turned it towards the firewall.
Attached the exhaust pipe(can get from Autozone, Napa, Oíreaillys, Pepboys they all carry the same one here in Vegas)
Closed the hood and started to pop off the wiper blades. Heres a step by step for those that donít know how.
Put your flathead or use your finger nails and place in slot.
pull up on tab
Remove flat head
pull wiper blade straight out.
Put some rags/towel down if you care about your paint.
move to the other side and pry up again
I had already cut a hole in here when I first got the Cherokee. So, If you are at this step then youíll need to find something to cut with. I used a 4inch cutting wheel on an angle grinder. COVER YOUR WINDSHIELD WITH SOMETHING. Otherwise youíll have little speckles all over it and will ruin your wiper blade.
I opened my hood back up and cut TWO holes. One so I can put the tube through and a second so I could take a quick look at the filter. I sanded the edges down with some sand paper I had laying around. If you donít want to use a peeping hole then cut the hole where my hand is with the sand paper.
Had an old postal tube end hanging around also and used it to temporarily plug the hole till my metal one came in the mail.
Mocked everything up for a test fit and was pleased with the results
added the filter and tightened up the hose clamps
Since I had the hole for the filter cut when I got the Jeep I found out that rain water got into the cowl. I added some AC ducting to help keep the cowl dry. So far itís worked. Iíll go back later and make an actual lid with gasket to make it water tight above the filter.
Buttoned everything up clamped the hose clamps down and took it for a trip down to get some lottery tickets.
1. First start up there was a sucking sound.
2. As it warmed up that sucking sound went completely away. My ears nor my wifes ears could hear it.
3. Driving around I loved the sound in the cab.
4. No whistle
Noise(Impressions after 1000 miles)
1. Still love it and will definitely do this mod again in the future.
2. There exhaust pipe likes to rattle at stops but itís rare. I still have to add something to cushion it between the engine.
3. I can touch the intake tubing/exhaust pipe after a long drive. Unlike previously stock setup my hand would start to burn if I touched the stock black flex hose. It does seem to be cooler.
4. Canít comment on mileage as I havenít been keeping track.
