Dealer states that factory installed original spark plugs need changing at 30,000 miles and replaced with platinum tip type. Wondering if this is neccesary? Vehicle runs fine.
The dash lights will not come on and now my right parking light is out and i replaced the bulb and still nothing. HELP PLEASE

I have a 2006 liberty 3.7 eng w 28000 miles. Car was hesitating cutting out and just running rough. I changed to Bosch platinum plugs. runs great now improved mpg by approx 3mpg. Origional plugs were NGK brand which I believe stands for No Good ****.
The Jeep comes with Platinum plugs from the factory.
And also a little secret-They are guarenteed from the manufacture for 1000,000 miles
Your Jeep should have Champion plugs in it.
