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

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.

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.

Used these to clean the throttle body and mass airflow sensor on my 2000 Silverado. They had never been cleaned before. They did a great job and my truck runs better than it has in years. Idles smooth, accelerates fast and shifts better. I'm very pleased and the price was less than other places, I checked.

the size is small but in practice it is enough for 2 or 3 times of cleaning and I don't think for the life of your car you would need more than that number of times. Buying bigger size is just waste of money for saving things for ages. if you have multiple cars then go with bigger version of them.

Was very easy to use. My MAF sensor cleaned up very nicely and I immediately noticed improvement. The throttle body cleaner works well too. Cleaned it very well.

Both products worked great! The size was perfect as I only seeing myself doing this once every 60K miles on my TB and every 25K on the MAF sensor. I still have enough to do two more throttle body cleaning and several more MAF sensor cleanings.

nice smaller sized cans for easy access to tight area's on the car. the mass air flow sensor cleaner you dont need much of but the throttle body cleaner you will use alot of but man does it clean well melts that carbon and oil right off of it. would buy this kit again if i needed to.

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.

Like the product's a lot more than others. It has been used ever since I heard about the company. Dislike the small sizes they sell as a 2 pack which in my opinion is deceptive . These large engine cars require extensive cleaning of the gasoline base cars. My take on it.Thanks
