I recently got my hands on 2007 Dodge Caravan 3.3 and I am thinking about changing spark plugs & wires on it. I know that some cars are very quirky about what brand of spark plugs and wires you use. And if you use wrong brand it will not work as good as it should.

Looking at buying NGK Iridium IX spark plugs and BOSCH spark plug wire set. Anybody had problems with these? Working good?

Cheers!

 

Is it running lousy? The OEM plugs are designed to last 100k miles and there's good evidence they will last much longer. Just one example but my van has 211K miles on it and still has the original plug wires on it. Runs great. Most experts are going to tell you to stick with OEM Champion plugs.
