Have you checked the How To list? Not sure how many are actually recommended. I'd say the airbox mod and silicon vacuum hoses are worth doing. If you don't have reversinf sensors, that's helpful. Also if you drive on unlit roads at night at least do the fix for poor dip beam, and fit better H7 bulbs.
