Post subject:  Question to guys with intakes
Been wanting to toss in a homemade CAI for the lib. I've seen alot of ya'll run open cones in the corner of the engine bay.

How do the temps do in the summer time?

I had one in the engine bay of my old grand prix and it used to get a little warm in the summers when driving around town. Pretty much was a HAI.

Pretty much sums it up. Really not worth bothering with. Drop a good flowing Amsoil Eaa201 in the box and call it a day.

You would be better off doing the rain gutter mod to direct cooler air form the grille area to a hole in the air box. Think you can find info by searching "gutter" or similar.

I have a K&N FIPK and honestly I think you need a hood scoop and a good sealed area around the intake to keep the engine heat out and get the cooler air in. Follow JJs advice and maybe get a snorkel!

If it is still in the engine bay it is "short ram intake" SRI
If it is a longer intake tube that runs out and down of engine bay, like a f'd up snorkle. then it is CAI.
It took me a long time to find this out. just thought I would share this info.

Was afraid of that!

Has anyone ever chopped up an airbox? I'd seen the K&N kit has what looks like a 'box' around the cone filter w/ out a lid. Thought about chopping my airbox up to house the cone.

I def. wouldn't be running it into the fender either, almost had this done on the gp, but never got to it. Can't have FWI when I'm crossing creeks and stuff!

Yeah, I'd realized that MNKK, just said it cuz must people think cai also.

FWIW. I just sent this reply via Pm to a member asking about the Amsoil Ea series filter for his 08 Liberty.

Just curious, what are the benefits of the air filter? I used to see alot of sport compact owners using K&N drop ins, and they all seemed to be happy. does it provide a substantial increase anywhere?


If you do some research on the K&N you will find unhappy people in areas where dust is a concern. (I see them on off road forums all over the Net) K&N filters are made to flow more air.....at the expense of Some filtering ability. Most of my wheeling experience has been in areas that have fine dust and I have consistently seen dust in intake air tubes w/ K&N filters even on street driven vehicles.

I used to love K&N but not any more. (*mostly because of the drag race flow performance they offer, filtering is hardly necessary on most drag cars though) Oiled air filter technology is ancient and unneccessary. The dry filters on the market such as AEM, Amsoil Ea series, etc. do not require oil to help filter the air and they flow as well as K&N and filter Better overall. Airflow in filters is a trade off, you can't have Zero resriction air flow all of the time and expect that a filter is doing it's Main job which is filtering. I personally don't want any extra crap in my engine so I use the Amsoil Ea filters. If I wasn't an Amsoil dealer I would Still use them as I feel they are the best on the market based on the research i have done into the other Dry filters. Marginally better in my opinion but that is all it takes to sway me. (also cheaper for me too as a dealer)
As far as providing a substantial increase, No. I am a firm believer that No drop-in or even "CAI" kit provides any major improvement over Most stock intake systems. 3rd party dyno tests have shown very small HP or torque improvements that could be attributed to other factors such as air temp, barometric pressure changes, changing from a dirty to clean filter, etc. Heck, I feel a performance increase and see better MPG's just by changing to fresh spark plugs. Todays engines are tuned better than ever to optimize fuel consumption and performance and there is very little to be gained by just switching air filters. I say that a fresh Wix air filter will show close to the same dyno gains that a fresh oiled K&N will. I also believe that the "CAI" intakes, custom air tubes, etc. are bogus too. They may show a small improvement but at the price you pay it isn't worth it and unless properly built, insulated and routed, cold Air isn't what most of them draw in from underhood in the engine compartment w/out having some fresh air source coming to the filter from outside.
As you can probably tell, I am not sold on K&N or most "CAI's".

I use the Amsoil Ea air filter because it is affordable, flows well, filters great, uses No oil or special cleaners to clean and is reusable. The truth is that a Wix air filter will work fine and filter well but you just throw it away when it is dirty so I go w/ the Amsoil Ea.

BTW, As of right now I am not showing an Ea series for the 08 Liberty. Can you measure the factory filter dimensions and LMK. I might be able to find out it is a common size.


Hope that long winded explanation helps. You will find Many different opinions on the subject so do your own research and draw your own conclusions. Unless you plan to keep your vehicle for a Long long time it is probably not a big deal what you use as long as you take good care of it.

* "back in the day" I saw consistent improvements in ET by just removing the K&N filter from the ram air of my 68 Buick GS 400 that I drag raced. I know of others that saw improvements by doing the same too. Of course I used it on the street to keep the bugs out because of the ram air.

I've run most of the common air filters available for the 3.7. Like everyone is saying, a good drop is all you need unless you're going to get a lot more cold air to a cone filter. The hood I'm running makes a huge difference at interstate speeds, but very little a low speeds. I've tried completely customizing the box surrounding the cone, and sealing it well against the hood, but it didn't really make any difference. I've even gone as far as a 60 amp 1 psi electric supercharger, but the difference is very little (about 4-5% at WOT), and they burn up really quickly.

You really need to consider the entire intake and exhaust system if you want to get much more through it than stock. It is designed to go together stock. For example, I'm running a Profinish-Proglass hood that dumps the air from the 21"X1" opening in the scoop through a 4"X5" opening in the bottom of the hood into the cone from an AEM Brute Force intake. This flows through a ported and polished throttle body from the Fastman, and into machined and polished heads. The exhaust has been upgraded after the cats with a Borla/Mopar dual outlet exhaust. This gets a good amount of extra flow, but the exhaust manifolds are still a chokepoint until I get the JBA headers installed. Once they're installed, I'll be going to the fully ported and polished heads with 206 cams and some 4.7 HO injectors to match up with the increased air flow.

I started with a K&N air filter before I knew about the Amsoil, then I switched out and noticed improved performance and milage. Then I sawthe PVC pipe street elbow mod : http://www.lostjeeps.com/forum/phpBB3/vie ... c&start=15
as performed by MonsieurGlen and I have found some new seat of the pants kick while retaining the stock air box with some minor dremel work. Milage and performance have both improved. :D :twisted: :D 8)
