Always save your OEM parts in California in case a re-install-for-smog is in order.

My Mini Cooper S was highly modified....all I needed to re-install (temporarily) was the factory air box for testing. Thankfully.

(Oh, I did that preemptively)

Yeah i kept mine all my factory parts i kept in a giant tupperware bin in my garage in case i ever want to put anything back to stock. I wanted to put in headers and possibly the microimage intake but might hold off until i smog my vehicle that way i dont have to worry about taking it back off and on again for the next 2 years.
