I got the 17+ diffuser on my 14 IS350 f sport. It fits like perfect OEM fitment. If it fits my 14 then I'll definitely fit your 16 lol. Most people at the dealership don't really know about part fitting or not lol. Not saying everybody there but most

Thanks! Did you guys order OEM from the dealership or got with LKQ parts?

I got lucky and bought it locally from a guy who works for a Lexus dealership. It came off a 19 Is300. Apparently that dealership was selling the diffuser for $380+!!!!!!!. Lol what a rep off. I didn't pay remotely close to that lol
