Feifel ducts

To the home page

Tigers were (for a time) provided with the "Feifel" air filter system. This was added to the outside of the vehicle, and it included four air ducts laid out on the engine deck.

Original duct tubing on 131

This is an original Feifel duct on Tiger "131". It is a thin strip wound into a helix, giving it flexibility despite it being made of metal. The cross-section is polygonal due to the manufacturing process.

Replacement duct tubing on 131

But Tiger "131" no longer has all four of its original Feifel ducts. The inner two are lost and have been replaced with these broadly similar ducts. Neither their intakes [A] nor their tubing [B] is identical to the original ducting; in particular, the tubing has a round cross-section.
