Evening all.

Got some wrx fog inserts for my 03 (blob) uk sti with the intention of using them for intake/induction cold air feed purposes. I know the more common method is to go through the Sti fog cover but i like the look of the fog inserts being used as ducts.

What i'm hoping for is for somebody to advise me what trumpets/bezels to use to fit to the insert size and make. I'm thinking an 89mm trumpet which has about a 135mm diameter from Merlin motorsports which is approximately the diameter of the hole in the insert. Any suggestions as to how to do it would be appreciated. Thanks for your time. Stu
