Intake Upgrade

Bought one of the Boss目's product -虫洞 aka surge funnel from a member last week.
DIY installed into the throttle body just take few minutes.
Tested for 1 week and I felt the car is more responsive in low rpm range, especially during 2000rpm.
Stand still pickup was improved compare to last time and I will test out more during high speed soon...

Open up the hose from air filter box to the throttle body

Just install it into the throttle body
