Finding the right part for your IS300
This page shows parts listed for the 2005 model year only. Open a part to see its fitment table, which lists the trims, body styles and engines it was made for. Engines that appear in the fitment data include the 3.0L 6 Cyl, so have your engine size handy.
Before you order
Compare the part number on your old part with the listing where you can, and check whether the part is for the front or rear and the left or right side. Left means the driver side on a US vehicle. If your Lexus IS300 has a trim or engine that is not in the fitment table, send us your VIN and we will confirm the fit.
