I'm in progress of adding a vent to assist air into the drivers wing where the snorkel was on my 1994 wrx. I got the vent off eBay and added mesh, but is the mesh I've used going to be too restrictive? Not sure whether I need to get larger diamond mesh?

 

Your air filter is a lot more restrictive than that and air gets through it. lol

 

Infact you don't even need mesh.

 

Yeh just without mesh you can clearly see into the wheel arch which doesn't lol very nice.

 

Also may put off anyone chucking stuff in there!
