Works really well as a cleaner..easy to use , fast drying , no residue

This product works very well as long as it’s used as directed. I’ve used it before with great success and highly recommend.

This bottle comes with a small straw for more precise spraying the mass air flow sensor. Unfortunately I couldn’t get the straw to insert into the spray hole. Nonetheless, I was able to clean the MAF sensor adequately enough to make my check engine light go off on my 2005 Toyota Corolla.

I use this to clean my mac and map sensors on my 2019 f150 and its perfect at doing g the job

Does what it is designed to do, cleans the MAF sensor. CRC is a trusted brand that I use frequently, and continue to do so.

Just clarifying the year and model of my car, so you guys can know what kind of Engine is improving!First of all, I am a MD, with 0 to 1% knowledge of a car engine operation. So, even for a dummy like me, the cleansing of the DENSO MAF Sensor, of a D4D engine (actually similar to the 2007 Toyota Corolla of my Father, even in location) is a piece of cake! Taking me between 5 - 10 minutes for a very noticeable boost in the car performance.Locating the Sensor in a D4D or VVT-i engine (Diesel or Petrol) is easy. Just locate the air intake (looks like a snorkel) that house the air filter, going forward into the engine you can locate the MAF sensor with the Toyota DENSO engraved in a plastic square, that is fixated to the air intake with 2 screws.First, remove the conector of the MAF sensor, remove the screws, and carefully remove the MAF sensor.. try NOT to touch it, whatsoever.Second, with the CRC 05110 Mass Air Flow Sensor Cleaner and the provided nozzle, apply a few sprays into the little metal conector that sticks out of the plastic housing. Don't be cheap and apply it thoroughly!-- CAREFUL, the cleaner has a combination of different Hydrocarbons derivatives, so it would be wise to use a latex glove to protect your hands in the process!! --Let it dry for a while, and then place it again where it belongs. Plug again the connector and wait for a few minutes before start the engine.From the first start, you can actually hear the difference between the old ignition and the new.. and the notoriusly different idle working of a Diesel engine! (it works smoothly and quieter)In the first week, my Gas consumption went from a 17.5 Km/L to a 20 - 21 Km/L (Metric System FTW)So, I'm actually going to use a lot of this for a while, especially every 5000K with my car Maintenance, hoping to get the old Gas consumption of 25 Km/L..! I love more and more, every day, my little Yaris.. :)

GOOD would buy again
