Hey guys, I was talking to a mechanic i know and was saying i'm gonna put an K&N in and he suggested also putting in a tornado fuel saver......you know one of those stupid fin things. Anyone know if these actually work? I've read people slamming them online but i've met people that say they kick ***. Opinions please?

 

It's a bull.

 

If they increased mileage or performance, don't you think that the manufacturers would install something like it.

 

and don't you think they'd install a k&N also? I see your logic but its flawed, companies don't necessarily put the best thing in there, look at the power steering unit on your bronco, they could have put better ones in right.

 

A vortex feet away have no effect whatsoever on what happens in the cylinder, especialy on a fuel injected car.

As for the K&N filter, does anyone know how the filtration efficiency compares to the OEM filter? I take that it's less restrictive, so it lets more air through, but that can also mean less efficient filtering, too. And that's a little difficult to measure.

In any case, I don't want to sway you -- feel free to buy that tornado thing, and report back on the mpg change.

 

don't even waste your money on these. Put the money into getting a k&n air filter or something else.

 

You can send me $60 and i can send you nothing. because it will have the same effect if you were to put a tornado in your truck. .:thumbsdown:.

 

Ditto to the negative responses here. They are "supposed" to increase turbulance in the inbound air. Take a look at the ducting of the OEM intake with all the twists and turns and the corrugated expansion section there is enough turbulance to bring down a 747 inside there. The flow on the OEM intake is fairly well optimized for the setup from the factory. (Straightening it out a bit might actually help).

The K&N drop-in filter does allow for increased flow rate and has better filtering efficiency because its an oil-bath filter. The oil in it traps smaller particles that the OEM filter can ever hope to stop. The recommended cleaning intervals are a bit ridiculous though. I clean mine every other oil change (more often if I've been off-road) rather than the 10,000 mile interval that they recommend. K&N and other oil-bath filters like it aren't a new idea, just the modern reincarnation of a very old idea. Many old vehicles, (30's-50's vintage) had oil bath air filters. They worked great but were messy and difficult to properly clean by "shade-tree" mechanics. Car manfacturers don't put K&N style filters in from the factory because there is too much "process" that must be understood to replace it and/or clean it. They can achieve air cleaning efficiency that is "close enough" with a paper filter that simply gets swapped out when it gets too dirty.

 

whoa there guys, i was of the negative opinion on them also but i just wanted to make sure i wasn't skipping on something that could actually work. It would be 120 bucks that i would send you also because the bronco requires two

 

Oh yeah well $120 would be good. And I do except paypal

 

Don't listen to these guys, go ahead and get the Tornado. It works great but if you want even better mileage you will want the 125 mpg carburetor that I invented and will sell you at a great price- you just can't tell the government where you got it, they've been searching for me for years, but they'll never find me here I'll give you my address so you can send the money for the carburetor, it's..hold on, just a second.. somebody is coming up my driveway, wait, oh cr@p... it's a black car, I don't recognize it...HONEY WE NEED SOME MORE ALUMINUM FOIL ON THE WINDOWS!!! HURRY UP...DON'T TELL THEM ABOUT THE CARBUR

 

LMAO!!! ok ok....Let me get back up in my chair.

What has been said before is true.....and only mentioned once was the distance. With fuel injection, and where they have you install the Tornado, it does nothing. I have modded the ones I got about a year ago and installed them up against the throttle body. I couldn't feel any diference but I did gain just under 2mpgs. Although I would put that to me cleaning my K&N Filter. Now if you can install one right above a carb, then yea it would prolly make a diff. But in in the fuel inj engines...unless it a throttle body where the fuel in merely injected down into a carb, it wont help.

Save your money and get a full FIPK system for about $350. That will help and it is worth it.

hehe JBronco.....you could make a sit com about government paranoia....LOL

 

is this what you guys are talking about?

billybob,

so you installed this item and didn't get any power improvements but you were able to almost get 2mpg MORE? if thats all thats happened doing the item installation well thats thats good enough for me. 10-12mpg is better than 12-14mpg.

agree?

what are some other bolt on mods we can do to our 5.8 broncos? i already have a KN.

 

Once again though, I did just also clean my K&N filter that I hadn't cleaned before in about 2 years. It was really dirty. I should of done one then the other to see what did help.
I also cut the tornado down a bit so it would fit directly against the throttle body and not at the other end of the intake hose.

 

Now if you want to really get pricey and gain miniscule power and MPG you can spend even more on a similar device that fits between the upper and lower intake plenum. Yes, its a real product. But a high grade turn signal fluid will be a better addition to the truck! Better yet, replace the muffler bearings with titanium ones!

By the way, JBronco, I warned you about giving me grief about the 302! A couple of well-placed phone calls and who's da man now?!
