Hi All,
I was looking for assistance on choosing a rear diffuser for my 20' is350. Because I have the mesh center on the rear bumper. Can someone point me in the right direction or shed any guidance?

 

i am pretty sure you can use any aftermarket rear diffuser 2014+ because they have all the same application. if you're looking to sell your rear diffuser, i'll buy it, i'm assuming you have the F sport one?

 

All the rear bumpers on 3IS (2014-2020) are the same, so a diffuser from any year (OEM or aftermarket) will fit any year.
The difference is in the exhaust. the 2014-2016 have the round muffler tips and the 2017+ have the tear drop tip.
So whatever diffuser you choose, just make sure it fits with whatever exhaust you plan to have.
Ultimately a muffler shop can replace the tips on the muffler with whatever you want.

 

We can get you a Lexon , Toms Racing, or NIA Auto Design diffuser!

Other brands like Skiper and aimgain we have to order from japan.
