So I decided to upgrade my intake part with limited budget. A high flow filter would be my first choice
From what I know, oiled filters may cause maf problem, so what I got is afe pro dry s filter.
Driver side air intake box got stuck in the engine bay for some reason, I took 6 screws out and managed to take both charcoal filter and air filter out. It’s tough one honestly
btw, the large screw that holds the driver side air box is t40 (should be t27 from I know) which is really weird
Good bye dirty filter
At this point I also took out maf sensors to see how dirty they were cuz my idle sometimes is erratic. There are some oil on the plastic cover (where is the oil from????)
I found oil in the intake tube also. Can someone explain this?
It took me 1hr or so to finish all this (driver side air intake box was really a pain )
I now can hear my turbo spool and feel slightly quicker throttle response
For power gain, I don’t know since I don’t really wanna spend $$$ on dyno for some numeric data
