Awesome Quality Engine Bay Caps!

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.
