opti vent lines
 

what are the blue things on the lines for? i broke one and need to replace it where can i get them?

I believe one is a filter to prevent anything from being sucked into the engine, and the other is a flow limiter/check valve. Its a dealer item, as part of the entire vacuum harness.

dealer = big $
 

thanks injuneer

i might have an extra one laying around. if you are interested i can see if i still have it.
