This has probably been done before, but everytime i search for sierra parts on ebay i find this.

This guy is selling a product claiming to increase your gas milage up to 31%.

Its a crappy piece of aluminium, which you have to bend yourself, and stuff into your air intake!
How can something 'blocking' your intake reduce fuel usage? If i put one in my mouth will i breathe better?

The hardest part to believe tho, is the amount he has sold, and the amount of happy customers who feel it made a difference! These people make me feel ashamed to be a member of the human race, how can people be so dumb? I guess for their complete stupidity they deserve to be robbed of their $24.

I honestly believe that anyone who buys one of these needs a Chuck Norris round house kick to the head.

Maybe we should start selling old blocked fuel filters. mine was great at reducing my fuel usage as well could be a money spinner!

there is never a shortage of fools!

may depend on the intake.

The old magna's 1990 1995 or so, they have an oval oxygen intake sensor which sits right in the centre of the oval.

If you put a air pod on one th eoxygen sensor won't get any air as the air is spin around the out side of the intake piping, and miss the sensor and make the ECU think there's something wrong and the engine won't run properly.

apprantly if you add a somethinglike this it forcestheair into the middle of the intake and the sensor will get a much better reading.

That's the only car that I know of where these things could work good.

If you fit a pod filter to a magna, you deserve the Chuck Norris treatment too! haha

if it directs the majority of the flow towards the center, then thats still an uneven reading. and besides the car is tuned based on how that sensor read the air in its current position. so now it would be fuggin up the mixture.

still dont work! you got had.

I've got a similar thing that spins the air.
It's called a turbo

so do i, but it doesnt do much maybe a cyclone would be better than my turbo.

though with high power mods like a cyclone it would probably void the insurnace

some car manufacturers actually put ones similar in from the factory

how stupid are they

wtf why would anyone believe this rubbish if it was that easy to reduse fuel consumption it would be a factory option with the millions of dollars involved in desinging cars something like this is i dont know wtf

hahaha, lol these things are funny. i wonder how many proud owners will have one of those crappy aluminium tags fatigue and snap off then their engine eats it. that'll save fuel, reduce their engine capacity by one cylinder

It is funny though, I read an article about a guy working on reducing the inefficiency's in his air system.
the manufacturers dont get them perfect - so its not the concept that you can improve on stock that is the issue, its what they are saying will improve it that is.

This guy found that by the time his air reached the engine it was quite a vacume and then retested all the way towards the air intake to locate which parts were restricing fplw so much. pretty interesting, then he reduced about 70% of the restrictions, and saw improvements, though they would not be the revolutionary 30% increase in power and ecconomy some of the crap out there offers.

Apprantly no, because the intake pipe is oval "0" it's not round "O" and the sensor is in the centre you need the air to be in the centre to get a proper reading.

If the air is spun along the pipe walls the sensor thinks there's less air than what there really is and the ECU richens or lightens the amount of fuel based on the amount of air coming in.

It's a common problem with the 1990-1995 magnas, I used to own one and on the magna forums everyone says don't bother with pod filters you can buy special oval pod filters which send the air down the centre.

hmmm, seems weird as when they created the fuel maps for the vehicle, i.e tuning it checking exhaust gasses for analysis. it would have been using data recieved from the intake sesor as well.

seeing as the ecu adapt mixture based on the oxy sensor in the intake, if after it was tuned, you do something which effect how the oxy sensor percieves the flow, then the car will say oh we are getting more air than 5 min ago so i better change the fuel to suit it. there fore just buggers up the manufacturers settings.

this might in turn give a change in performance, if the car was down tuned to give longevity etc. but it could also go the other way.

mehh

gotta love how the seller lodged unpaid item reports to all the guys that posted negative feedback....

I bought one for shits and giggles cause I was kinda sick of people arguing with me when i tell them it wont work, and there argument was I had never tried one (neither had they).

I have it sitting on my bedside table (its been there for ages) and i am waiting to get more stable fuel consumption figures so I have a comparison of before and after.

The funny thing is I might not use it at all cause I think the design (its shipped flat and I need to bend and round it myself) is a touch dangerous and I don't want it coming loose in my intake.

I have a few more questions when I get round to it (if ever).

Personally I would never buy one (touche), and do not reccomend them to anyone!

Even if this type of device did work (lets assume for arguments sake that it just might ), the small gains they would offer would be offset by the initial cost of the damn things ($14 isn't much, but I'm assuming sensible gains here). Oh and for the environmentally concerned, realise it costs CO2 emissions etc to make the little piece of aluminium(al. costs allot more than steel in emissions), more than you could ever save even if it did help...

I'd like to point out the one hilarious fact; the originally posted ad (link) includes a listing as suitable for a Suzuki Sierra. As a pround owner of a 63hp rocket I am really intrigued as to how a little piece of alumium can give me half that horsepoower again!!!

C'mon if you are gonna try and con someone, make it believable...
I'm also interested as to how I can "see" horsepower gains... Will they appear on my tacho?

If I had an ebay account I'd contact the seller and ask what gains can be expected in a Toyota Prius, they should be cosmic .
