Purchased these on ebay, never got a chance to install. Should fit any 92-99 BMW 3-series with a 6-cylinder engine (M3, 325i, 323i, 325is, 323is, 328i, 328is). From talking with others who have used these headers, they perform quite nicely, and they are higher quality than you would expect for the price.
