Spark Plugs....when to change

[Mazo EMS2]

Don't have a manual at the moment. Wondering when the plugs are due to be changed. 2010 RT has about 15K miles on it now. Once in a while it almost feels like it has a miss developing, so I'm wondering if it might be due. Is this a DIY'er job?

14,000 miles is the factory recommend mileage. Do the wires too. Call Bajaron.

I think the manual says right around the 14-15k range is when they are due. It can be a DIY project if you have the patience. The air box will be in the way of the front plug and it is a bear to get out. BajaRon sells the plugs and replacement wires and it has been recommended here to replace the stock wires as they weaken. The ones BajaRon sells are much higher quality. Once you have the air box out, I would leave it out and put in one of JT's filters instead...it will make future plugs changes a snap among other benefits.

My $0.2 anyway. Ymmv.

I also noted that you mentioned a miss developing. While you are in there, I would inspect and maybe replace the 2 small vaccum hoses on the left side of the engine if they are still stock. They also degrade and can cause "miss" type problems.
