Finish
Powder coated for protection from the elements, the textured finish will look awesome for years to come. Available in black, silver or red powder coating.
Boost Controller Mount
Besides a sleek new cover this part also provides a clean custom mount for your PERRIN EBCS Pro boost control solenoid. Show it off with a window to proudly display your EBCS Pro. If you are using OEM boost control, no worries this part provides a custom mount for that as well.
