Cleaning up my engine bay, im not sure if it has any true performance gains but it sure looks nice!! all you need is aluminum, jigsaw, 3 (6mmx20) bolts/washers!
i had some left over aluminum from my door panel project
i used a template from a friends car (do not use a cover panel that is branded by a company to trace!)
basic shape is cut
step up bit for easy drilling for jigsaw to enter repeat for all holes/ spots for jigsaw
first hole drilled
used jigsaw to enlarge the hole to the correct diameter

AFTER!!!!!
