140HP/310Nm Performance upgrade
1.9TiD 8V with DPF F270006461
Hirsch Performance has developed a performance upgrade also for the 8-valve version of the 1.9TiD engine. The fast throttle response and good fuel economy characteristics of this engine type with its fast-spooling turbocharger have been maintained, while providing significantly more torque above 2000rpm, and widening the useful rpm range with more power around the 4000rpm mark.
This performance upgrade is only available for vehicles with particle filter!
As always, the Saab original factory warranty is not affected by Hirsch Performance Upgrades.
