Grimm Speed Alternator Cover

Grimm Speed alternator cover install was easy and looks much better than the old original cover. I like the splash or red under the hood of my STI


The GrimmSpeed Alternator Cover looks fantastic in your engine bay! As you said the splash of red is great and its easy to install! We appreciate your 5 Star Review and your added pic!
