Yours more the normal spoiler, the other like EVO type.....Nice. Mine is a duck tail style.
During lockdown time I juz clean both of my car engine bay since the jazz for my dad & mom shopping & go out makan car is still clean and neat.
But the wira.... Yes,there is a lot of dirt,sand and those oil stain that had in the car for don't know how many year. Took me some time to clean. And also clean the throttle body with throttle cleaner.
The accelerate feel for smooth after the cleaning.
