Aftermarket Performance Mass Air Flow Sensor

[ArizonaCruiser]

Good Feedback

Yes... These reviews are what I was looking for. Thanks!

I should have searched the internet for the Product Id + Reviews to find some driver feedback like that. No specific Cruiser feedback, but V-8 full-size trucks including an H2 are equivalent in this case.

Indeed, it appears that an MAF programmed for more airflow by itself will result in a lean air/fuel ratio that throws the error code and a "Check Engine" light is going to be triggered sooner or later just like that H2 owner reported. The ECU won't just compensate for more air. To do it right, you would need to tweak the ECU with a performance program in tandem with a MAF like this.

None of that seems worthwhile on a Cruiser considering the GVW, full-time 4x4, and generally well-engineered factory specifications for the drivetrain.

That is all I needed to know. I'm just going to clean or replace my factory MAF, clean the throttle body, and be done with it.

Now, about those magnets...

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

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"

We need a guinea pig. Where is loud when you need him?

still waiting on those headers.

If you are looking for some increased mileage, I would suggest cleaning the maf, use a top tier fuel cleaner (BG 44k is top notch), make sure your wheel alignment is in spec, give the throttle body a good cleaning, and go easy on the pedal when you can.

Maintaining a constant 2200 RPM will give fantastic mileage...


and you'll develop the patience of a Tibetan monk.

I had one on my Nissan Titan that I sold to get my LX, it seemed to get up and go smoother and quicker was it worth it? I would say it wasn't wasted money. I am not a MPG counter though.

Thread is being brought back from the dead, but lets address a few misconceptions here: a mass airflow sensor does one thing - measures airflow. It doesn't control airflow. The ECU will determine the proper amount of fuel to add based on that measurement (along with other sensors). The only thing that actively controls airflow is the throttle body and camshafts. Airflow is passively controlled by everything up and down stream. Of those passive features, this mass airflow sensor will do absolutely nothing to improve airflow: "Made from the factory original sensor with advanced programming flashed in, The Power-Flow is fully compatible with your ride." That means the airflow through this sensor will be exactly the same as the factory sensor.

All this sensor will do is tweak the air/fuel mixture. Nothing more. There may be minor gains from that...but you're NOT getting 45% more airflow through the engine. I have no idea where that claim is coming from, but there is no documentation about it anywhere I've seen, and given the way engines work, I have no idea how they can support that claim...a 45% gain would be an astronomical improvement in volumetric efficiency...

I would definitely NOT support the gains of 45% but it smoother acceleration was noticed.
