COVER (HILL ENGINEERING)
It is certainly not common to have your 348 or Mondial t oil tank cover break or get lost -- but it does happen. On my personal 348, the center threads were completely destroyed and the incorrect plug had been installed, so it was time for a replacement. But at a whopping $250+ dollars from Ferrari, I knew that Hill Engineering could come to the rescue!
Now, a full billet aluminum cover is available from Hill Engineering for about half the price of the original. The quality is (as you'd expect from Hill Engineering) world class, and the price is down to earth.
