Mazda CX5 kf 2.5L oil catch can installed n video positive results highly recommended

Mazda cx5 kf 2.5L oil catch can installed at 27,000km, removed stock air box, using DIY aluminum pipe 3" CAI. Carbon buildup was very minimal on all values but i did clean it all up before installation.
Cleaned throttle body, mass air pressure, intake manifold etc.
Pcv value tube remain attached, use 12mm automotive hose connector join to 1/2" or 12mm 1.2meter length fuel line hose which connect to inlet of occ.
Intake manifold inlet with another 1/2" ,12mm, 1.2meter length fuel line hose to outlet of OCC with no breather. Everything runs perfectly no check engine code/light. Car feel new, no rough idle improve mileage. Highly recommended for gdi engine if u want to prolong your car engine life.
