**LOOKING FOR NAME OF PART**
 

Recently I stumbled across some photos of an FR-S on marketplace, and the diffuser on it looks real nice. It's very similar to the OEM one from Subaru, but it's different. I've spent 3+ hours looking for it with no luck, if anyone happens to know what brand it is that would be greatly appreciated, thanks.

BaysonR and any number of other white labels you can find on eBay or Amazon sell it as a "JDM Style Diffuser" for 2017+, which is most likely the product that you have in your picture. It's not meant to be used on the Zenki rear bumper, but as you can see people find ways to make it work.

It's technically modeled after the diffuser section from the Kouki TRD Rear Bumper Spoiler. The lower "diffuser" part was never sold separately, but it was a separate piece from the lip that was meant to be attached after painting the main body. It's pretty unlikely that the part in your picture is a genuine section from a lip kit, but if you really wanted a "genuine" one that you can do some custom fitting to your car, they sometimes get sold at auction from scrappers in Japan.

Thanks for the response EndlessAzure. It does look very very similar, I'm just not 100% sure it is that diffuser, OEM or not, it has some spots which lead me to believe that, I'll send a photo showing them.

Looks like the JDM style bayson r rear diffuser withh the nur spec style spats put together. Pretty much like what endlessazure said.
