Designed well. I used as directed. Personal observation: use the straw on side of can, do not stick straw inside sensor. Spray from at entrance of mouth of sensor using an amount as common sense dictates. My sensor surprisingly looked clean inside, used it anyway. Delicate sensor wire, maybe contaminants unseen to eye. At any rate, the product definitely serves its purpose. Haven't bought a new MAF sensor yet with 165,000 miles on my 2000 328i.

I had never cleaned my MAF sensor before, but my car was taking forever to accelerate, putting me in danger on a daily basis. I pulled out the MAF sensor and couldn't even see the two wires that were supposed to be there, because they were encased in gunk. A few quick sprays with this cleaner and the gunk was gone, leaving two shiny wires behind. Immediately after that, my car was accelerating like it was brand new.

Bottom line is, if your car feels like it isn't getting any gas, try this cleaner on your MAF sensor before handing the keys to a mechanic. It's easy as can be...anyone can do it, and it only costs a few bucks. If it doesn't fix the problem, big deal. At least your sensor is clean, and the risk is minimal considering the potential reward.

I bought a 1999 monte carlo (V6, 3.1L) last year with just over 120k miles on it, it ran... pretty good... most of the time... but occasionally it would stall or bog down at times. No matter, I paid peanuts for it, it has a nice warm heater, cold A/C, dreamy ride, and loud stereo, so I was happy. You can't win them all...

Well, the most recent time it bogged down I was going uphill on the interstate and it bogged down for a bit, but this time, the engine light came on. Ah-ha! A clue! I said... I took the car up to smyth automotive and had them read the code, which was P0101 (MAF circuit, range or performance problem).

I took the car home and sure enough it was putting out maybe 15 Hz at idle, 28 Hz at 3500 rpm. (you need an oscilloscope or frequency counter to measure the output with the GM sensor, should be much higher apparently, maybe 35-80 Hz). I contemplated getting a new MAF sensor but saw this product and thought why not try it? After the cleaning, as soon as I turned the key, the engine light went out. Performance was just like a new car! I floored it, and my head was thrust into the headrest 'with gusto' ;) as the speedo approached scary numbers rather quickly.

I showed the product to my dad and we tried it on his 1999 suburban 5.7, which has had the engine light on for years (has close to 300k miles now)... a decent improvment there as well.

Bottom line is, if your car is due for a new MAF sensor you really ought to try this stuff, remember it is a delicate and precise instrument so handle accordingly! Please do not try brake cleaner, isopropanol, simplegreen, or whatever else you might read about on the internet. (you know, the "trust me, I'm an engineer" crowd). Spend the $5 and get on with it.

This is still a relatively new product and is it seems like it is just starting to hit the tuner/hotrod scene (those high-zoot "oiled filters" can have potentially disastrous results on a MAF sensor!)

I used this on my 1995 Subaru Legacy. As far as I know the air flow sensor had never been cleaned. The difference with noticable, the engine ran more smoothly and accelaration was much better. The old Subaru ran like a new car again. I highly recomend this product.

My 2003 GMC Sierra 1500 HD 6.0L threw a P0101 Mass or Volume Air Flow Circuit Range/Performance Problem diagnostic trouble code. It did not show the check engine light, but my cruise control stopped working, so I scanned for codes and saw the P0101 DTC. I used this cleaner, which took about 15 minutes, and then cleared the code. My cruise control has worked fine ever since.

No more rough idle when braking is applied, after one month. You don't even need to remove the MAFS per YouTube, CRC Mass Air Flow Sensor Cleaner Video. I removed the big tube that Mass Air Flow Sensor seats in, next to the air filter. Then, I sprayed 45 times and air dry 45 minutes because it was dirty. You can spray less and air dry less if you want. This process was very easy for a newbie!

MAF sensors can become dirty with air particles over time. This is a great investment which in the long run can probably save you from buying a MAF in the future. It's easy to use and drys extremely quick. I used this to clean the MAF on my car. I can't say I saw vast improvement from using it, but the throttle response is a little crisper since the Air/Fuel ratio is probably optimal again.

Just as a note it does state on the back: DO NOT use on vehicles with Karman-Vortex air flow , e.g. Toyota Supra Turbo, Mitsubishi, and most Lexus vehicles. So make sure you don't have a Karman-Vortex (search on the internet to confirm if your car does have one).

This is worth the price. Clean your sensor every time you install a new air filter.

Seems to do it's job. Used it on my mass airflow sensor and have had no problems with it. Actually saw an improvement starting and idling after cleaning (I also cleaned the MAF wire contacts and replaced the air filter at the same time). Really good price for the can, you will only use a few sprays each time you use it... so it will last a while. Comes with straw insert as would be expected.

This great product is added to my '95 vehicle to keep the new air flow sensor clean along with the new catalytic converter that was installed recently. The addition of those new products with the mass air flow sensor cleaner gives my old vehicle better mileage.
