## Questions & Answers

**Q: How to use this ?**
A: Hi 
Please find the instruction below.
 Connect the injection device to the cylinder. Insert (stick) its needle into the rubber hose of the engine air intake and hang the balloon upside down (for example, by the edge of the raised hood) as a dropper. Turn on the flow of funds. Allow the engine to idle at 1500 rpm for approximately 30-45 minutes. Do not allow the engine to overheat. If the exhaust manifold starts to glow red (due to high temperature), stop cleaning immediately.

**Q: Is it comes with injection system?**
A: Yes
