vaccum check valves

[A4PLAY805]

so i got the P0171 code and check underneath the hood and yea a big hole on the one check valve that runs thru the intake box, covered it with electrical tape cleared the code and CEL hasn't came on after a day ... so my question is is their a difference getting oem ones for $35 each or $12 from ECS TUNING? thank u

i got one from the stealership about 6 months ago for $64 then bought one from ecs 3 weeks ago, identical. no difference

yea stealership wants $50 each and with my auto mall discount im lookin at $35 each which is the same as ECS price for the oem 1's.. ima replace all 4 check valves i knew this would happen sooner or later..smog due by december lol
