1955 Prince AISH-4


The Prince AISH-3 was only in production for 2 months before the new upgraded engine became available. Fitting the new engine to the AISH-3 created the AISH-4 model. The new engine was designated the FG4A-20, and like the previous model it was a 4 cylinder overhead valve 1484cc engine, but the new version had a change to the cylinder head design which raised the compression ratio from 6.5/1 to 6.8/1, resulting in a power increase from 45hp to 52hp. 


The car's top speed also increased from 110kph to 115kph.

The Prince AISH-4 was in production until October 1955, when it was replaced with the updated AISH-5 model.
