Intake other than K&N?

Does anyone have a CAI other than a K&N 63-2575?

I've been waiting for Volant to release one since last year so I'm looking to see what other options there are.

Show some pics as well!!!

I plan to put my Scangauge II on my expedition this weekend and see what the temp is from the out side air temp...and see if a CAI is worth it. From what I have heard the Ford factory intake is pretty good....but I will run some test to see.

I would save your money. Just get a washable dry filter.

I would be curious to how well the stock system flows and how much the temps differ from outside to the Intake air temp sensor. As Monsta stated a while back...his truck read the same temp from outside to the IAT sensor...which showed him that CAI was a waste of money. I am with Berry1234 and I would like to put my money to better use. But like I said...I am taking a little trip this weekend with the Expedition and I will see what the results are with a stock setup. ......stay tuned........I love that little scan gauge!

PS...... for what its worth....my 2004 Infiniti G35 shows about a 9* differance from outside temp to the IAT sensor.....with that said the G35 3.5 liter engine is not the most efficent either. I may see some improvement from a CAI on that guy....but how much?

Yep....On the road at highway speeds I had the same outside air temp as Intake air temp. No need for a CAI system for these SUVs. I have also talked to others and confirmed the same.

Now if we could find an inexpensive reusable dry air filter, we would be set.

hell I'm just happy to hear there's no need to drop $300 on an intake. More money

a cold air intake isnt going to help any on the highway, it will make a small difference when going lower speeds. At highway speeds there is plenty of air being blown into the front of the truck to keep the heated air vented out, now at lower speeds there is very little air being blown through the front of the engine bay, so a sealed cold air intake would likely produce slightly better results, does it make sense to spend $300 on one, probably not. I also have tested my temps, at low speeds the temps are anywhere from 100 to 140, at highway speeds they are very close to the ambient temp.

i am with you on this one, I am currently using the drop in K&N and am perfectly happy with it, but if someone would make a dry filter I would definately switch, alot less maintenance and they filter much better in dusty conditions.

Just for thought.....On my 2004 Infiniti G35 I have a 9* difference on my Outside air to Intake air......and it does not seem to care (highway) on conditions....it's always 9 to 10* hotter going into the intake. At slow speeds....it's way worse!

ok last night I did some datalogging for air volumes, maf intake temps etc. using my programmer hooked to the expeditions computer.

Sitting Idle the volume of air being sucked through the K&N drop in is around 230 to 250 units.

Driving anywhere from 45 - 65 the air volume is 450 to 490. Not bad for just a simple drop in.

Intake temps at idle anywhere from 30-50 degrees higher than outside temp. Driving under 40 mph, intake temps were around 25 to 35 degrees warmer.

While driving on the highway temps were about 5-10 degrees warmer than outside temp.

Can you compare these to the OEM filter?

It doesn't really matter what CAI you buy they all produce basically the same results. According to others they do not bring in colder air which seems wierd but they do draw in more air which increases HP...right?. I have the K&N CAI installed on my 08 Expy and I do know two things for sure, they look better under the hood then the stock intake plus they give the engine a more aggresive sound especially when getting on the throttle. I don't have any proof of increased performance besides gas mileage, according to the trucks comptuer I gained on average about 1-2 mpg. For the $300 you invest in a CAI your not going to get crazy performance...maybe a little. Not sure if Injen makes an intake for the Expy but I owned an Injen CAI on my last truck (2005 Nissan Frontier) and I loved that one. It seemed to give me more low end torque since the wheels spun out a little more when gunning it from a stand still. If your not going to do any more mods then a drop in filter will in my opionion be just fine. I have done a few other mods so figured I would do the CAI to maximize the HP gains from the other mods.
