💨 Why Add a Front Splitter to Your WRX or STI?
At high speeds, your car builds up air pressure under the front bumper, leading to lift and reduced traction. A front splitter redirects that airflow up and over the vehicle, producing downforce to improve cornering grip, stability, and high-speed handling.
The included splitter rods are essential for keeping the splitter level and supported — especially during spirited or track driving.

Aftermarket lip cracked but that’s my fault, I went to tight on the screws. Don’t be stupid like me and NOT use the spacers. USE THE SPACERS lol

These lads are the best in the biz. Hands down, the fastest shipping for car parts I have ever ordered (and trust me, I’ve ordered a lot of parts) and excellent customer support. I’ll be sticking with Aeroflow Dynamics for all of my aero pieces from now until the end of time.

I've always seen the Instagram pictures of Aeroflow's products, & always knew that it was their products I wanted on my STI. I can honestly and wholeheartedly say that they didn't disappoint. The splitter I received arrived safe and secured nicely. I'm not going to lie though I was a little intimidated when I first started this install and I reached out to Aeroflow thinking maybe I had recieved a wrong splitter or that maybe I selected a wrong option but the Aeroflow team got back to me right away with a solution they explained that the pre-drilled holes on the splitter are not meant to align with the OEM holes under the bumper. You will have to drill new holes through the bumper using the pre-drilled holes from the splitter to help you align when drilling through the bumper. Which guided me to a perfect install this splitter is everything you need to add some great aero/aggressive look to your car craftsmanship was top notch you will not be disappointed. @krizz_tofher for any other questions
