Anybody have experience installing an aftermarket mass air flow sensor to improve performance? I am interested to learn of any results you can share from experience. I haven't seen or heard much about this in the forum, so add the link if there is already an existing post on it. Here is an example of what I am talking about...

That would be an interesting upgrade, if it really does improve mileage. More power and torque is fine, but not at the cost of fuel economy.
 
A money back guarantee might tip the scales...but I suspect the only thing this "upgrade" does well is pad someone's bank account.

Maybe a dozen of us can chip in $10 each and have someone try it out.
 
"This high performance sensor replaces your vehicle's restrictive stock equipment"

How 'restrictive' is the stock unit? I have not pulled mine out to clean it yet, but I imagine that it will look just like the 'high performance' one listed... which will leave me wondering how it increases airflow.

Ditto. But need to know more about how the air is metered by the OEM unit. Is it just a sensor that relays the info/signal to the ECU to digest? If so I can't imagine, like you, what real difference the aftermarket unit could make to justify their claims.

Lots of snake oil out there.
 
Add a fuel magnetizer, intake vortex generator, and cold fusion injection and you'll get 100mpg into the wind! If only the Haliburton/BP/Saudi Energy cabal would release this technology to the public then the energy crisis would be solved. Good thing the Cabalists don't search the internet. :rolleyes:

The same site has a Landcruiser intake vortex generator too! (It must be good - same part #is the OE replacement for the Mercedes Benz ML55 AMG and the Kia Sorento)

From the OP MAF product description ...
Increases airflow up to 45 percent; This high performance sensor replaces your vehicle's restrictive stock equipment​

Where is the restriction in the stock MAF ? and what is less restrictive about the replacement ? looks like pure snake oil to me.

Probably just a sensor that sends a slightly different value to the ECU fooling it (how this will help is beyond me) into making some other (probably not beneficial) changes.

Called them. It is a recalibrated MAF to give better throttle repsonse. He threw in that it gave you 5 to 6 additional hp as well. We need a guinea pig truck.

I forgot the throttle body spacer.

and a OE replacement to boot! :lol:
 
I dumped several snake oils into one of my old minis, which resulted in a more expensive but still puny 22RE. I stopped all that nonsense at some point because power is not really what those trucks are about. I will avoid such things with my cruiser too, mainly because it has plenty of power for my applications already, and it is much more about reliability for me. there's my .02 and now i'm broke!
 
I dont see how a sensor is going to allow more air flow. For more airflow you would need a bigger intake system, and to make it function properly, you would need a bigger exhaust as well...
 
No one with an aftermarket MAF in a 100

I think it is very telling that no one on mud (thus far) is showing up to say they have an aftermarket performance MAF on a 100.

It seems to be an OEM sensor that is simply reprogrammed to allow more airflow than the stock settings. 45% is quite a bit more air flow. A bit surprised it is just plug-and-play so the ECU just adjusts to it.

I'm intrigued with the claims of +5hp gain and better throttle response but still skeptical particularly when it comes to tweaking the intake on a 100. On a tuned sports car, 5hp can be substantial, but the tank-like 100 is not geared or tuned for this.

Still waiting to hear from someone can actually report on this from personal experience.

Anybody???
 
I think that 45% figure was just cut and pasted from a K&N product description along with the "restricted stock intake" nonsense.

Check out the reviews here ...

Jet High Flow Mass Air Flow Sensor

They are mostly positive but a few stood out to me.

"But there is one thing does puzzle me. It looks exactly, and I mean exactly like the stock one, to include the numbers stamped into it. The only visual difference is the Jet sticker. Make me go hmmmmmmm?"​

"Gave a little extra power in acceleration to my '05 Silverado. Already had intake, throttle body, and exhaust. No better gas mileage...check engine light has come on, and says its running lean. have yet to call JET performance products to find out if it may be from the Sensor."​

"Installed in a 2006 Avalanche ran great for 126 miles when check engine light came on, reinstalled stock and cleared light. Contacted Jet and found out that the engine was most ly running to lean. Have now ordered a chip programer to compensate for lean running engine. Not sure how this will turn out."​

"I loved this product though during the week I had it then gave me a engine code on my '03 Hummer H2. Gm dealership said this is not going to go away unless you put the oem mass air flow sensor back in b/c it has a small grate like lookin grill that prevents this code that the afterrmarket one does not."​

"you can tell the differance. The only downfall is the check engine lite comes on and off since the day i installed it"​

Ah well, as I suspected. From the above it looks like the new sensor just reports less air flow to the ECU, and therefore runs the engine lean. That gives you the better mileage . . . until the engine complains and sets a code. Some engine do become "sharper" when you run them a bit lean, but that just gives you a jerky ride, not more power. In fact, you will have less power, it will just feel like something changed.

Programming the ECU as in the example above will give you (surprise surprise) exactly what you started with, in terms of performance and mileage.

Verdict: 100% snake oil.
 
Send me your money, I'll send you a sticker to put on your existing one and a free set of steak knives as well as ferrite core to snap around your TPS sensor cable and you'll be sweet.
Guaranteed to give you more bang for your buck or your money back (less shipping)!

You've got a deal, but only if you include the magnets that wrap around the fuel line...:doh:
