Haven't cleaned the Boxster engine yet. On my other cars I used Orange 409.
I warmered up the engine and the turned it off. Sprayed Orange 409 on all the engine parts and let it set for 10-15 minutes. I then rinsed with a gentle stream or water from the hose and wiped down with rags. Work great and much cheeper than Gunk.
Anyone try this on the Box?
