4721 Mass Air Flow Sensor Cleaner - 10 oz.

bought product in hopes of eliminating troublesome check engine light...cleaned contacts and works perfectly...exactly as described

Love this stuff use it on lawn mower and snow blowers it works real good.

I've been using CRC MAF cleaner for years, but they've gotten a little proud of the price, so I decided to give this stuff a try. Honestly, seems to work exactly the same for less money. It cleans well and evaporates quickly. I've not had any error codes using it, so all things considered, this product is a better value than ol' standby.

Works great

I was able to clean my MAF sensor for literal pennies on the dollar with this product. My fuel economy jumped 10 miles per gallon. The product itself was simple to use. The quick-drying formula meant I did not have to leave my air filter system open waiting for parts to dry. It was as simple as spraying the product, waiting for it to dry, assembling and you're ready to go

Really good for cleaning up MAF. It removed the dirt and quick dry too

This product is so efficient that the engine rough problem has been solved rightaway.

If you're like me and were at your wits end with stick drift in your nintendo switch, vr or other console controllers, THIS PRODUCT IS A MIRACLE! I tried everything from air duster to isopropyl with no luck. I thought I'd have to buy new controllers until I watched a video that recommended this product. Not wanting to spend another 60-100 dollars on new controllers, I finally decided to spend the 8 bucks on this and used it on both my Oculus Quest and Nintendo Switch controllers which were both riddled with awful stick drift and... JUST LIKE THAT! I havent had an issue since and its been 3 days. I'm so happy I found such an affordable and reliable solution!
