CRC 05110 Mass Air Flow Sensor Cleaner - 11 Wt Oz.

CRC makes the best cleaners ever. That's all I buy. It cleaned my MAF very well. It dries in 3 minutes. It's great stuff. It is very effective. Great value for the money. Streak free. Nice size bottle that will last me for years. Very durable. Highly recommend.

Worked as expected, Would buy again!!

Good value and works as intended.

I use this for bicycles. It cleans the bearings in the rims and crank with out disassembly then I use my air hose to dry everything quickly then I spray fresh lube on the bearings. It’s like brand new every time.

Used on a very, very old maf sensor. Cleaned all the dirt off, even the front vent that was pretty grubby. Dried quickly, no odor. Bit on the expensive side, but otherwise did the job.

We have a 2002 Nissan Pathfinder that started throwing the Check Engine Light. After using a cheapo ODBII scanner, we found a few codes that pointed at several different things. Strange thing though, we never got multiple codes at the same time. I'd reset the car computer with the scanner and then we'd get one code for a swirl sensor problem then we'd get another code the next time for a oxygen sensor and then we'd also sometimes get a code the ODBII sensor had no idea what it was (probably a manufacturer specific code that wasn't in the scanner's database). I first replaced the o2 sensor since it seemed to be the code most often thrown and also since it's a common issue with the Pathfinder. That seemed to get rid of the CEL initially. Then the light came back on. After considering whether or not we should just replace the swirl control valve (another common issue with this car), I came across a posting somewhere that the Mass Air Flow sensor could be the culprit to all these other codes getting thrown. Replacing the MAF sensor itself is kinda expensive, especially if you go the OEM route. So for kicks, I decided to give this thing a try. First off, this thing is really easy to use. It's almost like spraying pressurized water. Now it's very hazardous stuff, so use caution. This cleaner dries super quick. Once the sensor was cleaned and dried, I put it back in, reset the car's computer, and crossed my fingers. About 600 miles later, the check engine light has not come back on. I'm hopeful since prior to using this product, the light would come on after about 30 highway miles. If you're having a check engine issue and an ODBII scanner is showing some codes associated with the exhaust and airflow check systems, definitely try this out. A less than $10 solution to a problem that could have cost me several hundreds of dollars. As to the other marketing claims put forth by the manufacturer, I have no idea if it's true. A few horsepower here or there is really not gonna make a huge difference in the big scheme of things. But others here seem to swear by it...so who know.

My MAF sensor got the worst of the wildfire smoked that rolled through a couple weeks ago. The MAF sensor was completely dry in 10 minutes. It may have actually been less, but I was being overly cautious. The pressure from the nozzle wasn't excessive, and did not damage the sensor in any way. After cleaning the MAF sensor and letting my car idle for ten minutes, I definitely noticed an improvement. (Throttle response became sluggish and acceleration was crap). The only draw back is after 10-15 sprays, I still have a nearly full can of MAF Sensor Cleaner. Oh well. I'll hand it down to my kids when I pass away in 40 years since it will probably still be around after cleaning the sensor every time I change a filter (which I had not done prior to this, lesson learned).

This cleaner does an excellent job of removing dirt, dust, and oil deposits from the mass air flow (MAF) sensor, which can help improve fuel efficiency and overall engine performance. The 11-ounce can is easy to use, with a well-designed spray nozzle that provides precise application. Simply spray the cleaner onto the MAF sensor and let it dry—no need for scrubbing or wiping. The formula dries quickly and leaves no residue, making it straightforward and mess-free. I’ve used this cleaner on my car's MAF sensor, and I noticed a significant improvement in engine smoothness and responsiveness afterward. It’s a great maintenance product to use regularly to keep the sensor in optimal condition and prevent potential issues. Overall, the CRC Mass Air Flow Sensor Cleaner is effective, easy to use, and a valuable addition to any car maintenance routine. It offers excellent performance and convenience, making it a top choice for keeping your engine running smoothly. Highly recommended!

Not value for money since the same item is available in the US for as low as $11. But you might not be able to carry it in your luggage anyway (very volatile compressed item) so I had no choice but to order it here locally and pay 3 times the amount. Needed it to clean my cars Mass Airflow Sensor and item arrived several days before stated delivery date. Cleaning done and car working properly so I guess it did its job. Wish it was cheaper, especially when I know what it actually costs. Great item though.

Best in the game, cleaned my air flow sensor perfectly.

Solved my MAF sensor issue in minutes

great product works fast , dry's fast would buy again.

Esta muy bien cumple su cometido, muy recomendable
