ISX15
The XPI fuel system delivers a precise quantity of fuel at ultra-high pressures.  This, together with more robust electronic engine controls, enables multiple injection events per cycle.  Flexibility in injection timing increases fuel economy and performance while decreasing exhaust emissions.

ISL9
The ideal engine for larger luxury motorhomes. With power up to 400 hp and 1250 lb-ft of torque, the ISL9 can accelerate at any speed and quickly climb the steepest grades even when towing. The ISL offers a very strong engine brake for extra braking capacity and added driver control. With 20,000 mile (32,000 km) oil change intervals, the ISL saves money and time when it comes to maintenance.
ISC8.3
Built on a reputation of delivering additional performance when a little extra is needed. With up to 350 horsepower and 1000 lb ft of torque, the ISC8.3 is designed to provide the performance to deal with heavier loads and steeper grades.
ISB6.7
The ISB6.7 features a High Pressure Common Rail (HPCR) fuel injection system that enables multiple injection events per cycle for cleaner, quieter and more complete combustion.  The proprietary VGT Turbocharger has been improved as well for strong throttle response and dependability.
