## Questions & Answers

**Q: كيف يتم الاستخدام**
A: يوجد انبوب شفط هواء خلف بوابة الثروتل و هذا الانبوب يكون في ثلاجة المحرك و يجب ان تقوم بأزالة انبوب ثلاجة المحرك و بعدها تقوم بتركيب الانبوب الخاص بمنتج لكوي مولي مكان انبوب الثلاجة و بعدها تقوم بتوصيل الانبوب الخاص بمنتج لكوي مولي داخل علبة منتج لكوي مولي لكي يكون الانبوب موصول بمنتج لكوي مولي و ثلاجة المحرك في نفس الوقت و بعد ان تتأكد من توصيل الانبوب جيدًا يجب ان تذهب لتشغيل المحرك و وضع عدد دورات المحرك على 1500 دورة او 2500 دورة و المقصود بذلك هو ان تجعل الار بي ام على 1.5 او 2.5 و يجب ان تقوم بتثبيت الار بي ام على 1.5 او 2.5 و ان لاتجعلة يهبط او يرتفع حتى ينفذ المنتج من العلبة و يستطيع اي شخص ان يفعلها في البيت دون الذهاب الى اي ميكانيكي او مختص و اذا كنت تريد ان تتأكد بأنك استخدمت المنتج بشكل صحيح ، يجب ان يخرج الدخان من العادم ( الشكمان ) اثناء تشغيل السيارة و الضغط على الار بي ام و من الافضل ان يكون هناك شخص معك ليساعدك ( للعلم يختلف مكان ثلاجة المحرك من سيارة الى اخرى لكن يجب عليك التركيز على اول انبوب موجود خلف الثروتل مباشرة )

**Q: Where do we have to add this product ? Is it added to the fuel tank or to the intake air duct?**
A: To the air duct by using a spray and spraying it into the throttle body while the engine running at 2500 / 3000 RPM

2. Than was drive 5 km.
3. Than was put rest fuel in to the full thank.
