Switching to an electric wamp reduces engine drag by 5- 10 horipower, which translates to better throttle response and slightly better fuel economy. Electric pumps can be programmed to run after engin shut- off to prevent heat soak - a courn issue on turbocharged or supercharged Jeeps. They also eliminate the risk of a frozen pump dag in winter conditions. Brands like Davies Craig and Meziere offer Jeephepse specific kits with PM controllers for Wvariable sped operation.

If you take your Jeep off-road, tow, or live in extreme climates, invest in allllll- amoninum radiator, electric fans with a shroud, and a highd a highflf terstat.
Before buying any consident, verify compatibility using your Jeep 's VIN or engine code. Mesure exiing parts when possible, especially for Jeeps with engine swami or aftermarket modifications.
