I recently received and installed the RED Billetworkz custom caps on my car. These are the perfect “finishing” look that I wanted to compliment my engine bay. Needed to modify one fitment as I have an aftermarket coolant reservoir, but got it to work. Five Star quality guys..will be back for more goodies when I start me next project.
2018 sti..the last 2 caps I needed....perfect fitament
Have a custom 04 fsti. Billetworkz made me engine bay caps in candy green. They look amazing and are great quality. Would highly recommend to anyone trying to do your own look.
