Okay - I ought to just buy one from K&N - but .... I got an oval aluminum air cleaner for my bird and it needs a real oval element. The little housing is made by Wysco (12 long x 8-1/2 wide) and with a 1/2" carb spacer and nice sized element it will just tuck up under the bulge in the hood. The manufacturer lists a couple of elements in a stick-on on the underside of the lid - but both are round and you have to (sort-of) mash them into the capture groove milled into the housing. Duh.The housing groove is 11.5 long and 8.0 across and 7/8 wide. K&N lists an oval element that is 11.5 x 8.125 - but I'm thinking it will look pretty goofy on each side if I have to scrunch it in there - which is my complaint about the existing set-up. After using their web site to search, I found a K&N number E-9136 that is an oval 11.438 x 7.875 x 60mm ht. that should work just about right - but also more than a few bucks to try it out. Also will have see if it interferes too much on the inside edge of the groove.
The element is supposed to be for a Renault R-19 (fuel injected) of 1989 vintage. Went looking for a paper version - and can't seem to find anyone stateside with replacement part. Anyone got an idea about where to look? Like a brand of import car parts? NAPA guys say they don't believe in putting French parts on a T-bird and the usual cheapo parts houses are hopeless even for a Ford....
