Hi all,as I was only a lowly B3 driver can anybody provide an answer to this question? I believe the air-cleaner on the early models used up 100 HP of engine power,this was rectified by a mod designed by the Israelis,and consisted of an electrical motor mounted on the side of the air cleaner at approx 45 degrees. I spent God knows how many hours wallowing in oil and diesel only to be told on another forum that I´m wrong..........am I? Any pics? Where the Fcuk is GDav when you need him!
