I have had one of these in the FIPK of my 4.0 L Cherokee for approx. 6 years now. Wondering if anyone here has heard of these? Pretty much used to only get them at local speedshops but now I see Tornado has a website now, and a video to watch on its homepage in case your curious. Enjoy!

Did it give you any mpg gains on your Cherokee? I was looking at some other gimmics online like the gas magnets or the vortec cyclone which is a aluminum vortech that you put on the air intake and causes the air to form a vortech there for making it more fuel efficient. I wonder if anyone on the forum has tried any of these gimmics well I guess we'll find out.

When I did all the bolt on's to my 4.0 L 6 yrs ago I bought the Tornado (in the case of the Cherokee the FIPK K&N kit has a 2 7/8" tube leading into the TB so I have a ki-75 Tornado in it which is 75 mm but has a + or - of 4mm). I installed these together along with the programming, all at once. Lots of extra power (roughly 30-35 hp/torque) w/ the Hypertech programming and the FIPK/Tornado install. I did all 3 things at once, so I have no way of knowing what each piece did for me separately. Now I can say that before these improvement to the 2000 Cherokee I was getting around 15 to 18 mpg (city/hwy) and after I was getting roughly 17/21 and the power was noticeably improved, but do I know for sure the Tornado gained me any more power by itself? No. Do I know if it gained me any more gas mileage by itself? No. But I've always suspected its helped a very little bit at least. But hard evidence, no, sorry. I'd put the Tornado from the 4.0 L. into my K&N on my Commander but I need an 85 mm. unit for the K&N on my 4.7 L because the tube on its kit is 3 7/16" diameter. I threw up the link just to see if anyone has heard of the product. I am going to order the larger one for my Commander. Since I can electronically monitor gas mileage onboard it, I guess I really could see if anything changes. I'm actively bidding on the 85 mm on ebay right now from a guy named jiddishelvis so wish me luck...if I don't win that one I'll just go ahead and bite the bullet and buy one through my friends speedshop for the retail price of $65. Since I don't do a lot of highway driving it will take me a while to get it, install it and track enough miles to see if it is truly giving a mpg gain. Like the guy says in the video, nowadays even 1 mpg savings is good, if it really does that then it will pay for itself again in my Commander....if not, well its not much money to spend trying.

Very interesting article that uses fact. You may wanna read before wasting money.
All those are junk except the Tornado...and again, tested on a dyno. Can't stress enough how that is not a real world test, and isn't upstream of 65 mph of air going into the inlet...but nice try at debunking my actual data gains that I observe w/ my Flashpaq. If people don't own something, then go on the internet to try and disprove it because it sounds like magic or something then you really should find a better use of your time...now if you do own it, then you would already know what I know, it actually does work. Another example: Notice how I don't enter into conversations here about body lifts or rock crawling...well that is because I know nothing about the products, don't have any of the products installed, nor do anyone I know, so I stay outta making remarks about something working for an application or not because I'm a gentleman and try not to sound like I have an internet education when in the real world it would be zero....get my point? If you don't have any real world experience with a product, its my point of view that you shouldn't comment on it at all!

My bad your right. Popular mechanics don't do this kind of thing for a living. They didn't use the Tornado in there test and state it was a 10% HP lose. Do you have the dyno results from before an after the install. Using a programer does not do a validate representation of the performance gains of another power adder. So in lay mans term the change in humity and air temp could skew you numbers alot and using one power modifier to measure the gain of another power add-on is like saying a K&N stick alone adds 15 HP!

So why does it matter to you then...ego flaw? Give me a break...get a life, don't just come to websites to spread hate....its not a nice trait. I never said that the gain can be replicated on a dyno. I really don't think it could be...but a dyno. isn't the real world, its not going down the road at 60 mph now is it? Clueless right? Please. Yet another person who should learn to stay outta conversations about things they don't know about....sadness.

Slow your roll, your recommending a product and providing statements on the performance of the said product. Wouldn't a individual looking to purchase a product like a scientific unbiased test of the product to compare to the recommendations of some Joe Smo? For all anyone could know is Joe Smo has intergeity issues and can not provide facts for statements made. I just want to afford everyone a option to see a unbiased opinion. I know its a joke and a waste if money! :rofl:

You seriously need to stop sending me threatening PM messages! I knew you were trying to be a jerk, but now you've violated all forum rules by continually sending me threatening messages and posting stuff on my private board...your obviously a psychopath.

so should i get one of these or not
No. We had a thread on these a few years ago. Don't you think if they really worked that the vehicle manufacturers would put them in as OEM parts ?

IMO (my opinion) You really should not.

They really do just act like a restrictor. They decrease the flow through the intake and reduce power.

The physics AND real world dyno's do not lie. I've seen dyno's first hand, and my profession is based around the principles involved in analyzing such cases of airflows and pressure gradients. I actually never saw this link until it was posted in the other thread, but it backs up everything i've said recently on the subject:
http://www.popularmechanics.com/cars/alternative-fuel/gas-mileage/1802932

In the end, it's your money. But I highly recommend not falling for this gimmick. $.02

Think of it this way:
The engine is "pulling" air into the combustion chambers. Adding the Tornado does 2 bad things. First, it decreases the surface area for the air to fit through (restrictor). Second, it deflects the air which slows down flow. So now you have a restricor and decreased flow.... The only way you would not see reduced power (or no power gains depending on the engine/intake specs) is if you somehow increased the atmospheric pressure around the vehicle to make up for the extra work the engine has to do to pull the same volume in that it would have been able to without the Tornado installed.

question, Doesn't K&N and fix the airflow to the intake? I thought there whole deal was they tested and design there CAI to smooth out the airflow making the engine suck air more efficiently. So if this added to it I would think K&N would of made it or recommend it at least. So the way I see it sticking something in there is messing with there design?Would this tornado help a stock intake system? because you know those stink at getting air to the engine? I would think putting one in a K&N is messing with years of design work.

It doesn't matter what intake you put it in, it will reduce flow in that intake.

If you put in an aftermarket intake to increase flow over stock, and then put the Tornado in, it will reduce flow back to the stock level or worse.

If you put in in a stock intake, you will reduce flow in there as well.

One of the main benefits of aftermarket intakes is due to the trade-off that manufacturers have to do with keeping the engine "quiet". Just like the exhaust, the intake tubes have baffles built in to keep the engine quiet because that's what 99% of the population wants. The problem, these baffles hinder flow (but not enough for a significant decrease in performance for most driving styles... WOT is where most aftermarket intakes help, not part throttle).

Edit: Cant find it but someone recently posted a picture of their stock intake tube next to the Airaid intake tube... that picture is worth a thousand words!
