V6 Diffuser subtle awesomeness

Fairly simple install. All hardware required was included! Smaller hands would be ideal but doable with grown man hands. Looks super sweet once installed.

Perfect mix of subtlety and function!

I stayed away from aftermarket rear diffusers for a while because most of them are really obnoxious in terms of how they look relative to the rest of the STI's rear. This version of AeroFlow Dynamics's rear diffuser is absolutely perfect in that it actually is functional in terms of producing down force and smoothening air flow. However, it does this whilst complementing the existing OEM of the rear bumper. The mounting solution is great too, no need for any drilling! I personally used some loctite for the bolts attaching the diffuser to the brackets and it's held firm after countless driving tests in various conditions. You could get some nuts if you want even more peace of mind, but they're likely not necessary.

Looks Great!

This diffuser is perfect if you’re wanting a more subtle, but still aggressive look. Installation is easy and the product is top notch. Looks great paired with my V3 rear spats!

Sick!!

Hands down the best quality diffuser ever! I had another companies diffuser which was made out of plastic. Aeroflow's Powdercoated alum material is top-notch and super strong! Highly recommend it if you are in the market for a good diffuser.
