As stated on the Moog website, K90332 is the ball joint part number 05-06 RSX. However, this is not the case. After squeezing out my old ball joints and comparing the two next to each other, it turned out that the mug joint would not fit the hole in any way, it was too small. I would recommend using BB6 Prelude ball joints. Picked them up at my local Napa and they dented right away. Otherwise very solid construction; as you would expect from moog.
