7 Steps To Power & Mileage

Jeep Wrangler 3.8L UpgradesIf we’ve heard it once, we’ve heard it 1,000 times. The ’07-’11 JK’s 3.8L minivan-sourced engine is a turd. But is it really? Yes and no. Tasked with pushing such a heavy brick, its 202hp does a pretty good job once you get comfy leaning against the rev limiter. And that’s the downside. These little engines are really lacking in low-end grunt. You have to make ’em scream to get anywhere. Most owners tend to lug ’em down low, which makes the JK feel slow and doesn’t do any favors for the engine internals. And the high load placed on the engine every time you encounter a hill spikes exhaust gas temperatures, which heat-cycles the exhaust manifolds. Next thing you know you’ve got carbon buildup, oil consumption issues, and big cracks in your exhaust. So what’s a minivan engine owner to do?
