If you want a CAI, buy a K&N, only due to the build quallity of K&N. All CAIs perform the same, and all they will give you is somewere between 5-8 hp at the wheels. No reason to buy the expensive ones.

Negatives:
- Oil based airfilters will get in your MAF sensor.
- Fitments issues are very likely on the classic alu tube design ones.
- You will not feel any difference in performance on a stock motor.


My recommendation;
- Get a K&N drop in filter, they do just as much IMO.

After waking up at 3:30 AM I pounced upon this thread.....now I glad I havn;t put the trash out today for pick-up as I yesterday put a K&N filter in my '11 Sport......the old (brand new) filter is in one of the barrels......I'll be taking it out ASAP this AM.

Hummmmm......yet another "improvement" debunked! This is the main reason for joining a site like this. There is better "real" information here....thanks. I'm going to be out $35 odd bucks but I'm not going to wreck my baby either. Thanks!

I understand the poor technology behind an oil soaked filter in anything but a clean lab environment, which is commonly the filter media in CAI's. My question, and not to feed the sharks, is how about the "dry" filter systems that are hitting the market? Airaid now has an oil-less filter (Syntamax) for their CAI's, would this help to alleviate the glaring negatives that hilldweller points out?

I would think that better filtration would be an improvement, but as was mentioned earlier, the computer system monitors the air/fuel mixture. I don't think you will get an added benefit unless you change the computer programming to also increase your fuel flow. More air will not give you more power without changing the computer programming and parts of the fuel system if the injectors can't provide enough fuel for the additional air.

Here is the biggest problem behind the CAI/higher flow intakes: More flow isn't needed! If your stock filter and intake are capable of flowing 1000 cfm and your engine only needs 500 cfm there isn't anything there to gain. Filters roughly the same size as used on a JK are feeding engines making much more power without any trouble at all.

As there is so much info on this and my brain is mush already today, are you guys recommending buying a K&N filter or not?

Or do you just prefer sticking with the factory filter?

I just wonder as eventually I'll need a new filter and want to maximize the life of my engine.

Stick with the OEM filter. K&N gets a bad rap. There are more expensive drop ins that last longer but they require cleaning.
IMO it's not worth it.

A K&N filter is better than your stock airfilter, yes!

Thorttle responce will improve alittle bit.


HOWEVER; You will not see any real noticeable performance gains. The drop-in airfilter will maybe add 1-3 HP at the wheels and at the peak of the RPM, and you will see an incerase in MPG of about 1-2 max.

AND !!!!! - The oil on the filter is very likely to get in your MAF sensor and cause it to get faulty readings, and pop "Air/fuel mixture too lean" codes, and possibly as a result of this random misfires as well. This is NOT the end of the world, and can be fixed by simply cleaning the MAF with MAF cleaner, and if you cannot get MAF cleaner, you can also use Brake cleaner and carb. cleaner.

Do the "performance" drop ins all require oil?

I am not aware of any that does not, and I have not tested any drop-ins that didnt.

But I have done test with K&N, Green filters and a few other ones that I don't remember the brand name of. And all except K&N performed just as well as the OEM airfilter and didn't show any improvements in MPG or HP.

And when we tested air restrictions they were almost the exact same as the OEM, the little that some of them flowed better was not enough to make any difference.

Only K&N airfilters had less restrictions in it and was capable of flowing more air than the OEM filter, but like mentioned in this thread its all controlled by computers today, to balance the air/fuel mixture, and the less restrictions in an aftermarket airfilter will not really make any difference when it comes to it, other than the ones that I have mentioned.

There are several performance filters that don't require oil, or are at least not a gauze type filter. I know Amsoil has a reusable "paper" filter for most applications, and I have seen ads for others. Amsoil also has an oiled foam filter that works well. I will never have a K&N filter on anything. After finding dirt, feathers, bugs et al down stream of many of them it just isn't worth it. They don't filter well and have no business on anything that will be used in an environment involving dust.

The K&N, absolutely not!

The Amsoil oiled foam I have in my Lightning and have been very happy with it. My only complaint is that it came with too much oil on it and it drips off, runs down the cold air tube (a real cold air tube) and leaves a puddle on the driveway.

My wife had the oiled foam Amsoil in her Camaro, but replaced it with the non-oiled paper Amsoil when it came out. She didn't want to mess with the oil and the reusable paper can be cleaned with the vacuum cleaner or gently blown off with compressed air. There was zero power difference between either of these filters and the K&N on her car, all were within 1 hp. I think they were all worth about 3 hp over stock with an aftermarket airbox lid installed. Worth nothing without the aftermarket lid.

Unless you plan to keep a car for a long time there is no value in buying a reusable filter. Regardless of how long you keep it there is no value in buying any oiled filter because the cleaner and oil costs more than a new paper filter. I believe the reusable paper Amsoil cost me about $25 3 or 4 years ago and has likely already paid for itself because I have been able to clean it instead of paying $13 to replace a stock one every year or so.

OK . the RIPP SC is the best way to get more RW HP and more of it for about 4500 - 5000 bucks. Which Air filter are they using? it looks like a CAI type. Has anyone performed a oil test after running the RIPP for a few miles? I know they say (RIPP) has 3.8s on the road for 100k and better, with no problems. Is that to their product they are boasting about, or our motors?

I think this thread as multiple discussions going.

weather or not a CAI is worthless.
Is oiled better than non.
K&N sucks.
Drop in filters OEM or aftermarket.
What I miss?

A super charged engine needs air and lots of it. I don't think it's a matter of a CAI, it's
The brand used. Some have prefilters I believe??

I use a K&N cai,the viper TB,and flowmaster exhaust and i like it. Plus i turned the mirror upsidedown, cut my antenna down to 14 inches and refitted the ball on it, drilled a hole in the outside mirrors for water drain, use a dash cover, a double hitch extention for support under the spare, did a lift to eliminate the stink bug, removed the headrests for better view, put on a bug shield, a locking gas cap, a hood lock, grab handles, sheep skin seat covers, remote start, cb system, lock box under the seat, 2 light bars, front hitch reciever, stubbed the front bumper, hothead head liner, dead pedal, mud flaps on the front, dual horns, cab cover, spiderweb shade, side trim, I-rack, window tint, trash can, floor mats, heavy-duty tire carrier, i like the stock 17in. wheels and use a vanilla bean scent air freshner. The only thing i regret getting is a TB spacer. There...i`m out.

An F/I engine will benefit from a CAI, an N/A will not really see any real gains.

The larger alu. tubes and more breatherable airfliter is only good for about 5-8 Hp at the wheels on a N/A unless it has P&P intakes and heads and a cam, nd even here its about 10-12 HP that they will gain from a CAI.

But still F/I engines see maximum gains of 15 Hp at the wheels.

There has been reports and claims of 30 HP gains from CAIs but I have never seen anything close to this, even on build engines, so I think this is very unlikely IRL.

I have never heard or ever seen a TB spacer ever make any difference or any gains, TB spacers are absolute BS.

Sorry i must have missed the discussion on the CAI allowing excessive dirt in the motor. Another, (JimBox) discussing the only way to get more RW HP is to install a RIPP SC. I was just asking which type filter the Ripp system is using, due to my silly reasoning that I think that system is passing a lot more PSI than a stock filter. So is that filter worthless or not.

I think Ripp uses AEM.


Edit: yes

I dont claim to be a scientist..but..

When you take two identical jeeps

Jeep 1 bone stock.

Jeep 2.. Mopar CAI, Mopar/Viper direct plug in throttle body, Custom Cat-back exhaust with 3 inch pipe, and a Superchip running 91 octane program

EQUALS..

Over 10 car lengths in a 1/4 mile...


Something is making a difference..If its what you want go for it, nobody keeps a car forever so why worry about the little things in life..

Read this quote from the site. I do understand they will tell you anything to sell a product.
I always feel my jeep runs better in the morning- when the temp is cooler 1-2 HP, maybe more/less?
Ever been a test? It's a difference I can feel, the engine just feels better.
With a good CAI system, I would think you can get similar results--although minor. It's just they are not cheap, is that minimal gain worth $300?

"It all starts with airflow. The more air that your engine breathes, the more oxygen it receives. More oxygen results in a better combustion. Better combustion translates into more power and better fuel economy. This is why your vehicle runs better on cool mornings than on hot afternoons as cool air is denser and contains more oxygen. You can feed your engine more oxygen by reducing the restriction of the airflow"
