Re: Airaid or K&N?

I fitted the Airaid /oiled with pre-filter. Found it to be pretty good....some issues from other Aussie forums reporting that the K & N doen't seem to filter out the very fine dust we encounter in the Aussie outback, seems the Airaid copes O.K.

I can confirm that I have obtained measurable improvement in airflow simply because my fuel consumption has increased. (Management system providing more fuel for stoichiometric burn ?)

Re: Airaid or K&N?

I to have a 3.7L and am looking to upgrade the intake. Maybe it'd be easier if someone who really knows there facts could give us 3.7L guys a list of available intakes and how they stack up against eachother? And of course the price range haha, just an idea, thanks guys!

Re: Airaid or K&N?

Well that makes sense to get a dry charger @zeropsi

Its made to do its job, they dont make their products to account for heavy moisture in your condition, and thats what the DC is for. Its just a slip cover, would save you money in the long run.

You'll have this problem with any CAI, aside from a few which also use an air box, you choose based on what you've mentioned.

Go with K&N. They Dyno EVERY vehicle and show the results on their website. "You get what you pay for"

Re: Airaid or K&N?

I personally went with Air-Raid kit because K&N did not have a full resonator delete and it also did not appear to custom fit to a 3.7L engine. My engine definitely gets more pull at a higher rpm. I got the dry filter because honestly I do not look forward to cleaning the filter and reapplying after a thorough inspection. If you get a CAI I assume you are going to get a tuner and different exhaust. Then you will get the most out of it. More Jeep owners praise Air-Raid over K&N. I wish AFE had made a 3.7L air intake. Would have gone with them no question.
And that is false about K&N Dynoing every vehicle. If you look at the charts it specifically states it is 3.7L Jeep Liberty. Yes it is the same engine so if you are okay with close enough results then that is okay as well. I would count on getting 4-5 hp on either one and would notice the difference in performance between either. You will get more out of it with a tuner and cat back exhaust switch out from 2.5 to 3".

Re: Airaid or K&N?

Been there, done that and aftermarket intakes lose low end and torque, and throttle response. The Dyno results are frankly BS, as those were likely not done on a car up to operating temp, the graphs start above 2000 RPM, (because there is so much loss below that) and it only shows WOT results, not how it drives. Nobody just drives at WOT unless it is a drag only car, and it is how it drives on the street that matters; the stock intake works the best.

Re: Airaid or K&N?

K&N does make a full res box delete, but only in aluminum. But I completely agree with air raids plastic tube there over K&N.

@dms I only saw gains in throttle response, and thats compared to my K&N drop in filter. I have no way to measure actual gains/loss to torque. I also have a video of my 0-60. I'll let that do the talking.

Also, I get about 26mpg highway now on hilly highways so I don't believe there is any loss in torque using the butt dyno. And of anything, the low end is greater due to the fact that I have to barely tap the gas pedal to go.

I'd agree on using the stock intake, if it were a straight tube with no kinks or res box. AND if you got rid of the itsy bitsy straw/snake like breath tube chrysler uses to draw air from the grill to the box, and put in a fat straight tube to the grill.- if that makes sense

Re: Airaid or K&N?

yeah but with the k&n intake u cant even drive in the rain. Since the bottem of their intake is open to the elements. and i shouldent have to spend more money on a dry charger that only lasts a year just to use there intake.... at least the airraid uses the bottem half of the stock air box im sending my K&n system back tommarow and if i can a deal ill get the air raid kit for sure!!

Re: Airaid or K&N?

I've had mine for 3 years in "the elements" with no problem. You still have body paneling an a fender well there between it and the environment.

If you're worried about that, get a snorkel

well when after driving in a rain storm your filter is soaking wet and white from all the oil getting washed away there is a big issue......

Re: Airaid or K&N?

Morning everyone. I have a 2005 4.7L V8. I am looking to make improvements to my Jeep. I use a CAI on my 5.7 L RAM along with a SuperChips tuner. I want to do about the same thing for My Jeep.

This Jeep is new to me. I plan on it being my daily driver now and want the best setup I can put together for daily driving in Indiana.

Goals
Improve fuel economy
Improve drive ability - low end throttle response


Anyone got any ideas?

Re: Airaid or K&N?

You're opening up a can of worms here hahaha!! Some people like myself like the CAI, some dont. I personally have the k&n with DiabloIntune and love my setup. Stock with CAI, I lost low end but top end was greatly improved. With the tuner I have the option of "Throttle boast" which reverses and improves over stock the throttle response. IMO you probably wont gain any power or tq, but mpg's and ease through rpms will be improved..
