Easystart is a spray that starts cars as the name suggests, often brake fluid cleaner is used in its place.
As with all aerosols it has a big long boring safety warning on the back, easystart is an excellent piece of kit and it really does what it sais on the tin, I dont know what it is in easy start that makes it so volatile but I would urge you to read the instructions.
I have seen a VW golfs airbox blown to bits when easystart was misused, (too much) if you do use it it is perfectley safe as long as you follow the instructions to the letter, 1 second spray really is a one second spray, no your car is not special and it does not need a double dose.
easystart is sprayed into the airbox and thus inhaled into the engine directly, if you use to much it flashes back and ignites the fume in the airbox and produces a sound that can only be described as “gunshot” followed by flying pieces of plastic airbox, i have seen it once and heard of it happening to freinds at least 5 times
Be careful with easy start, and read the instructions, it can go very wrong very quick if you dont.
