4.7L Powertech V8 ExplainedPowertechV8.com |
Chrysler's Powertech engine series is sometimes called the 'next generation' of the Magnum series. In fact, the Dodge marketing folks still used the 'Magnum' name for a time when describing the Powertech. The big pluses that the Powertech has over the Magnum are two spark plugs per cylinder, aluminum cylinder heads, plastic intake manifold, and single overhead camshafts. The Powertech could be found only in trucks. These were the Dodge Dakota, Durango, Nitro, and Ram, Jeep's Grand Cherokee, Liberty, and Commander, plus the Chrysler Aspen, and Mitsubishi Raider. The production run for the Powertech is from 1999-2013. There's very little aftermarket support for the 'next generation' engine, but with proper maintenance, like the Magnum, these will last forever.
