Starting at the end of the 2005 model year, the 4.7 HO engine became availble in the Dodge Dakota. The all-new 2005 model Grand Cherokee’s offered the new 3.7 V6, the standard 4.7, the 5.7 Hemi and the new 6.1L Hemi SRT engines. The HO engine was discontinued in the Grand Cherokee at the end of the 2004 model year. The HO engine is designed to run perfectly on standard octane fuel, but for maximum performance Jeep recommends premium fuel. The performance modifications (listed in the chart below) added 30 horsepower and 30 Ft.-Lb. For the 2004 model year, Jeep added the HO as an option on three new special models, the Freedom Edition, Columbia Edition and the Rocky Mountain edition. The HO engine was a Grand Cherokee exclusive for the 2002-2004 model years, available as an option on Limited models and standard on the Overland – but not available on the Laredo. A performance enhanced “HO” version of the popular 4.7-Liter V8 engine made its premier in the 2002 Grand Cherokee.
