Quick facts

• Part: Bosch 6720 spark plug
• Fits: 2007-2011 Jeep Wrangler V6 3.8L and other vehicles
• Condition: New

A misfire, rough idle, hard starting or lower fuel economy may mean worn plugs, but a weak coil or a fuel problem can produce those signs too, so find the cause before swapping parts. With the engine off and cool, a removed plug's electrode tip and ceramic insulator show wear, deposits or cracks.

Fits

It also fits the 2001-2010 Dodge Grand Caravan V6 3.3L or 3.8L and the 2001-2007 Dodge Caravan V6 3.3L. If your car isn't one of these, open the "Vehicles it fits" section and check your exact model and engine.
