After it's arrival, I installed the intake system on my car last weekend.
I had tested it for few days and able to feel more punch during low rpm with better pickup too; this is good for daily driving situation.
I also noticed during cruising; I only need to pedal lighter than before to get the car maintain the speed too.
Still not really tested on the performance during higher rpm... definitely will try it out soon...
The intake system consist of few parts actually.
Air funnel aka. black hole
surge intake at air box + angle joint
surge intake at throttle body aka worm hole
