:unsure: We have replaced our 86-88 front bumper cover(crunch at the pumpkin) with a 89-90 front bumper cover that has larger brake duct openings. Are the Brake ducts for the 89-90 actually larger to fit the cover opening? the stock catalog list a different part # for 89-90 ducts. Anyone have a gently used set of ducts or are we better off to order new from Mazda? :eclipsee_steering:

You are right, the openings are larger on the S5 bumper. I'm confused why you need any stock parts though? I assume you have the Mazdaspeed ducts pictured below, route a 3" hose to them and add an air inlet in the front. Get an inlet like the ones here: http://www.pegasusautoracing.com/group.asp?GroupID=DUCTBUMP

You can get 3" new or used hose and air inlets off ebay if you want to save a few dollars. Here's what I did, found some fancy used CF one's on ebay from a Nascar team, slight trimming and they fit just right.

The S5 actually has ducts that bolt in but still need mods to work. I attach the ducts to the bottom of the bumper bar (black fiberglass unit behind bumper cover) so I can pull the nose quick for working on the front. No need to remove hoses. Tom send me a pm with your contact information so I can get you splitter pictures.
