CRC Mass Air Flow & Throttle Body Single-Use Cleaner Twin Pack Kit

The MAF sensor cleaner cleared my check engine light immediately! Easy to use, and easily accessible part under your hood. Try it! (I had driven on dirt road, which I suspected clogged my MAF sensor). Worked!

I am NOT a mechanic by anyone's standard or wildest dream. When faced with an expensive error code, I was told by the person who ran the diagnostic that I could try cleaning the Mass Air Flow Sensor ($10 for cleaner and 20 minutes of my time) before having it replaced ($300 for part alone). He showed me where it was located on the engine and I told him I would try. I watched several videos multiple times before braving the project. I removed the sensor, sprayed the product, allowed the sensor to dry, replaced it after 15 minutes and started the car. I drove back to the shop where the mechanic cleared the error code (I couldn't) and it hasn't come back on. I drive a hybrid and had noticed the mileage was decreasing from 34 mpg average to 29 mpg average. It's coming back up now and I expect it will return to 34 - or better. Pros: Easy to use. Inexpensive. Cleaned well. Cons: need to have some kind of gloves on hand (I have medical gloves available) to avoid contact with delicate sensor. Without watching the videos first, I would not have known.

it's Compact and quick so you can use it for a check engine that's something with with dududu with the throttle body and the cleaner so it's pretty good.

This is a CRC product used to clean (aerosol style) the Mass Air Flow Sensor and the Throttle Body. There are two separate products because the MAF Sensor has to be a solvent that doesn't harm plastics. Like all CRC products I have used this is excellent. The two-pack approach is great and I was able to clean two cars with it. My cars were not that dirty despite both having over 200k miles. With a really dirty car maybe the pack will only clean one car. What a product! What a deal! Just had to drive to my local Walmart to pick up Great!

As a Sparks Reviewer, I have been given the CRC Mass Air Flow and Throttle Body & Air-Intake Cleaner to give you my thoughts and opinion on them. I have a 1999 Ford Taurus that has 182k miles on it. It started running a bit rough and was throwing out some codes regarding the air-flow system. So the CRC Cleaner came in at the perfect time. I took apart the Air duct between the Air Filter and the throttle carefully removed it and used the Mass Air Flow & Throttle Body Cleaner squirted it about 10 times and let it dry thoroughly. Then started using the Throttle Body Air-Intake Cleaner sprayed it down with a lot of the cleaner let it soak in for a bit took a rag and cleaned it till it was completely clean. Put it back together and started it up and trust me it started right away and was sounding good. I took it for a drive and to my amazement, my car ran completely smooth. No issues with stalling or going up the hill or trying to cut out will at a stoplight. I also watched my gas milage before I was getting poor gas mileage and this seems to have done the job. Instead of spending so much money to replace the Mass Airflow. So my opinion on the CRC cleaner is it definitely does exactly as it is intended to do and the overall best thing is IT WORKS. Highly recommend!

This CRC twin pack is a great, no-nonsense solution for routine intake maintenance. The single-use cans are perfectly sized, so there's no waste and no guessing how much to apply. It makes the process quick, clean, and beginner-friendly. The mass air flow cleaner works exactly as advertised — it evaporates fast, leaves no residue, and safely removes buildup without damaging sensitive sensors. The throttle body cleaner cuts through grime effectively, helping restore smoother idle and throttle response almost immediately. Quality is solid across both products. The spray patterns are controlled, the formulas feel purpose-built, and results are noticeable after use. It's an easy DIY job that can make a real difference without special tools. Overall, this CRC twin pack is a smart buy for basic engine maintenance — effective, convenient, and well worth keeping on hand.

These are the perfect size bottles for everyone else who doesn't work on cars all day every day and just needs enough for a few future cleanings.

I like that it was a two pack of the spray that I needed to clean up the throttle body and M.A.F Sensor. Both was a nice handy size, but depending on your needs on the throttle body to clean it, the small size may not be enough.

His cans are a lot smaller than you think they would be, so they're not going to last long enough to completely finish the job and the can. For the mass air sensor cleaner arrived without aerosol pressure.

this is not what i ordered. If they were out of what I ordered then do not put something similar in its place.
