A special fuel injection unit has ram tubes of larger cross section and 2510 longer than those of the regular production design.

Official Niva imports to the UK ceased in 1997 due to the importers having difficulty in sourcing the GM fuel injection unit required to satisfy ever-tightening UK emissions regulations.
