This dude here, has a very good product.. it makes sure ur engine throttle is clean which helps combustion and better response. Ur engine feels like brand new! have my word for it. And he is a great chap! Pls try out this product. You can feel the difference if u have never cleaned ur throttle body before like mine. And his will not wet ur spark plug! *thumbs up* Jus tried this product few days back and I can feel the difference already!
