Jaguar XJ6 4.0 MAF Up for sale is a Good working Jaguar 4.0 liter AMM / MAF. This also fits European / UK model Saab 900-Turbos (most) from 1989-1993 with the lucas injection system. This will NEVER fir a saab 900 in the US. The part # is Lucas (73350A) / 73350 A -- Match this with your original. unit is used and is fully runtested in an actual car - works well! I bad AMM can cause a lean running condition, lopy idle, a no start, runs but has no power, random stalling, or any other strange running conditions. This unit looks to be pretty recent, in very nice physical condition. This is CHEAP compared to new or rebuilt, even at wholesale prices!
