First I would like to say that these cans are quite small they're about a third of a big can so the value for the money is okay but you don't get much then again for cleaning a mass air flow sensor you don't need much also throttle body and air intake cleaner it works really well as you can see for the throttle body but you have to make sure you only use throttle body cleaner And second if you decide to wipe inside of the butterfly or take your throttle body apart when you put it back together you have through the throttle body out of whack and out of calibration now I have tried relearn procedures over and over and over nothing would work I had to go to my buddy who was a mechanic with his $10,000 scanner to relearn the idle procedure so I do not recommend cleaning the inside of it unless you're absolutely sure you can relearn the idle yourself you can wipe the front plate but do not take it apart do not disconnect the throttle body electrical component and do not open the butterfly because this little $10 project might turn into a couple hundred dollars if you have to have somebody relearn your idle that being said do your research Google YouTube whatever you have to before you start taking things apart other than that the product is great hope this helps
