"点增压效果" may happen on track, 180kph+
Agree with 向后看的鱼 "不如换一个high flow panel filter replacement就好了,放到原厂的airbox里面".
Stock airbox is well designed to create resonance which helps induction (for NA car is very important).
Open element air filter system is likely to suffer heat soak... Engine bay air can get above 50degC quite quickly at traffic.作者: 178654837 时间: 2012-4-4 16:48:44
