Fayz, lucky for you, I can read it:
It says:
1. Power booster: $45
2. Installation cost: $23
3. Fuel Savings: $34
4. Seeing frantic customers searching for translation: Priceless.
It also says: if you have any questions call 010-68714283. In Fine print it states: "before calling we advice you learn chinese"

Always here to help 😉
