Yes. "K" with any number behind it is good.

I've only had my car a month but I notice an erratic idle from time to time at a stop light and hesitation immediately after I installed my Airaid at low RPMs in first & second gear. I pulled mine out today and it has the X with the S through it.

Is there any difference if I purchase it through a PM or through your site?
Zip: 06042 I'm a newbie. Still not sure why I keep seeing all the "PM sent"'s

No, you can order right off our website.

That is an easy way to check!

What about Jet Performance MAFs?

[Mikamaro]

Are there better MAF out there than the OEM Strong one from GM?

Hocus pocus. There is no such thing as a "performance MAF sensor".

No "window" but on the sensor its as follows right to left ink stamped:

AFH70M-43A…….2X04…….15865791

what do I have?
mine doesn't look any of those in the pictures..

Ahhh I found it, I have a K24...

You are good to go.

Thank you for starting this thread, I had a weak one, just changed and what a differance, changed how the car idles and throttle is crisp, amazing such a simple fix.

Happy to hear that.

GM uses two supplier for Camaro SS MAF sensors. The simple explanation is that "weak" sensors from one of the suppliers are not showing the same resistance levels as the "strong" sensors from the other. Both work fine when the car remains stock but when additional airflow is introduced the "weak" sensor can start to become a problem.

The MAF sensors that have been identified as "weak" read 1560-1670HZ at idle with the A/C off while a "strong" MAF reads at 1800MHZ. During on road, light throttle input the MHZ are slow and weak in response to throttle changes which causes hesitation, throttle lag, and poor driveability. At wide open throttle the "weak" MAF shows 120-170MHZ lower than the 8600MHZ the "strong" MAF sensors will show on the same car. Depending on what intake modifications are made the fuel trim with a "weak" MAF can range from -25% on the high end to -3% with just a simple aftermarket panel replacement filter.

So what kind of performance issues will a "weak" MAF sensor present? Slow throttle response, low RPM bunking and surging, choppy idle, bogging when downshifting or applying quick heavy throttle inputs, and more. The good news is that all you have to do is pull the "weak" sensor and install a "strong" sensor and within seconds fuel trim is back to 0% and MHZ are back to 1800+. This will instantly change the personality of a car as was demonstrated in the threads below.

Issue SOLVED strong MAF

Strong MAF sensor. Believe the hype


How can I tell if my MAF is "weak" or "strong"?

It is very simple. Remove the MAF sensor from your intake tube and take a look at the code inside the indented window. Any single letter MAF is "weak" and any MAF that features a letter followed by a number like the one in the picture below is "strong".




Setting things straight

There are two points of confusion that seem to constantly come up when this topic is discussed:

1) This is a hardware issue with the MAF sensor and not a tune issue. The issue can not be corrected with a tune.

2) The "weak" sensors function just fine and are within OEM tolerances when the car remains in the stock configuration. Once additional air flow is introduced due to modifications is when problems arise. Because of that it is not something that GM will replace under warranty.

I just read this, I have a 2010 6.2 manual, I have a CAI, Vmax throttle body, ARH complete exhaust, and run a catch can with a custom tune. My car does as you described, can you elaborate? is my air flow sensor a suspect for the low rpm surging that I have? if its possible how would I know and how could I get the better one that you speak of? Well, I just went out and checked, mine is k10. I have had this problem for over a year now, been back to the tuner, and of course it would not act up, been to the dealership where I bought it and they feel that it is a timing issue or a fuel issue but can not do anything without flashing it back to factory settings, the car has lots of power, and as long as its not slow speeds on surface streets then its good to go, but it drives me freaking crazy, it almost acts like a bad plug or plug wire. All of which has been replaced, and the sensor has been cleaned as well. Do you think its in any way a possibility that even tho its a k10 that it may be weak? Thanks, Ron Tilley.
