Oh, of course not. Different brands have different workmanship, different performances and different prices, just like cars with four wheels. Why is QQ so different from Ferrari?

HKS belongs to the world's first-class brand, and the intake efficiency and stability of mushrooms are first-class. At present, there are many cottage products from small factories in China. It is recommended not to buy them, which can not isolate the external dust well. A large amount of dust entering the cylinder will seriously affect the life of the engine, and the intake efficiency is not good. This is a price-for-money, and

it is best to buy the whole intake system. I recommend bellows, which is more suitable for mushrooms in China.
