Getting close to 30K. Has anyone changed their plugs yet? What did you use and how did they do? I have heard a lot about the Autolite 3923. They are a cooper core plug and seem to take alot of the ruff idle out of our trucks.

I replaced my plugs around 2000 miles with bosch platinum fusion. Did not get any benefit from it.

I have heard that the platinums don't work well with our trucks. I bought the Autolites and will let you know how they did when I get them installed.

Got my new plugs installed and they work great. Much smoother idle over the factor Champion plugs. Seems to feel about the same while driving. I recomend these plugs to anyone who needs to change theirs. BTW, I did mine at 25,000 miles, the manual says every 30K.

Okay, im going to refer to a previous post on this one http://www.mitsubishiforum.com/m_166338/tm.htm

Bosch plugs specifically are horrible. Good old classic NGKs are the best

Not for the Dodge built V8 Raider. The OEM plug is a Champion not NGK. Have not read or know of anyone who has used NGK plugs in a V8 Raider. The OEM plug for the V6 Raider is a NGK plug.

I was talking about the eclipse... ignore that part. For the most part.. NGK owns all

Agree NGK is a very good plug.

Glad we agree : )
