none - very satisfied

 

Great! I leave for Quantico to go to the FBINA till the 28th. Gonna do t when I come back and will post my results

 

hey dukie564...not trying to steal your thunder just trying to inform some jeepers on other options like yours they can do. nice write up!

i dont have anybody i know that has done it this way but im thinking of trying it to see how it works, cuz like others said....i dont like the look of the snorkel, but love the hidden look!

 

$17 intake >> $175 intake

but yes i've seen it run to the passenger side before with the filter in the cowl - That is what is necessary in XJs with an ABS system. Still can be done way cheaper than that kit though

 

Forgive a noob for bumping an old thread.

For those worried about water seeping into the airbox thru the drain holes, you could seal them up and install a small pvc check valve (remove the spring) or a sewer float valve provided there is room.



"Flood-Guard operates like a check valve to seal off water back-up caused by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. Then the Flood-Guard float rises to seal off the drain opening until the water recedes."

 

Awesome!! Just awesome.

 

Still waiting on those pics----

I'm thinking the location is different on our years. Another snorkel thread I read mentioned the wiper motor on the drivers side that's why the hose was run to the passenger side due to clearance. But the snorkel actually came up through the cowl and pulled air from outside.
In reference to your #3 response, is there a baffle or something in between the left and right sides underneath the cowl? I haven't taken mine off yet to inspect for this project. If not, i can't see how the noise would differ from the opposite side.
You may not really feel it, but it will rob some air from the ac/heat system. These motors pull air pretty hard.
Have you had it through any deep water lately? I'm curious to see how it holds up.

 

Think he was saying there is noise on some other cowl intake because of the filter style and location. The factory airbox and filter will muffle the noise.

 

Lyon, This is next week`s project on mine! This is a great area for air intake just look at any NASCAR intake,they all use the cowl area so you will get the added benefit of cool air at Hi way speed with a slight ram effect maybe even helping the M.P.G. in the warmer weather as well as a slight increase in power,our 4.0`s are only pulling maybe 200 c.f.m. at part throttle. I think the cowl area is large enough to supply plenty of air for both the engine and fresh air for the cabin air needs,even at W.O.T.
As far as winter with ice covering the cowl don`t forget the cowl drains to both fender bottoms so there would be enough air to run the engine,I also like the idea of running the intake on the drivers side as it it`s farther from the blower intake! The noise from the intake is going to be less with this set up in part due to the two tight 90s being so close together.If the system is sealed up well the only way water will get sucked in is if you are in so deep that it is coming over the hood.
I have been thinking about doing this for some time now,time to stop thinking about it and make it happen LOL

 

@Lyon: No there is no baffle between the sides of the cowl. As slick761 pointed out, sound isn't an issue because I don't have the filter in the cowl area, just the intake tube.

Haven't been able to go out lately, but the system has always worked great when I did. It's my summer setup as well due to it being a true CAI (better than my intake under the hood for sure during hot weather).

 

Anyone thought about wrapping the whole intake in heat reflective material to further help with.cold air and stop heat soak? Worth it?

 

Good deal man. Looks like I have 3 Xj's to try this on.

 

Take some pictures when you are done and do a little write up.

I too am circling this project as it take little to no money and only a few hours to do. The more information I get as to what it takes to do the cowl intake the better for me.

 

I will definitely have pics! The problem on my XJ is that I have the ABS module still hooked up so mine has very limited space. Does anyone know of another shorter air box from another vehicle that I could use to do this mod? I'd take out the module but I don't want to mess up a good working brake system right now. Plus, I just have too many other things to do so I was looking for an alternative box. I've seen people use round canisters but I can't find the threads anymore. Help!

 

no jacking my thread, but it would be good info for anyone with ABS if you did a write-up for how you did it. I'll post a link to yours in my writeup for people in that situation.
