HPS Shortram Air Intake Kit 2006-2013 Lexus IS350 3.5L V6, Includes Heat Shield, 827-597

The kit was relatively simple to install. You need to be familiar with the engine and basics regarding the needed tools, but it took about 2 - 3 hrs to install. Part of the kit needs to be assembled before you install the parts, other wise it might be under 1hr. In the end, you can tell there is a small increase in performance and without a doubt it sounds better than the stock air box. I would recommend it to another Lexus IS owner.
