I will soon be +t'ing my 1993 240, and I am putting great emphasis on the job looking as OEM as possible. I have been reading through the forum and weighing my options as far as the airbox goes. I want an OEM looking airbox, not a pod filter...not that there is necessarily anything wrong with that. I'm leaning towards the gutted b21ft airbox, but don't have access to one, as they are getting more difficult to obtain. Has anyone used the airbox off an early 240 with the b20? I have located one for a good price and am leaning that direction if it works reasonably well.
