Check out these epic plugs LOL Sposed to be gapped .05" I had to use so many stuck on my gap tool thing that I didn't even want to add them all up. Lets just say no where neat optimal. Ignition coil was bad, to say the least. They were arcing, not good. So we took the one from our 01 caravans and slapped it in. Was temporary till the new one came in. Alone with wires and plugs. Runs much better now (obviously lol) Not bad either since this is the first time they have been changed in 217,000 MILES. Yep, a 2010 bought in 2011 with 217k miles lol. That, plus washing my truck was how I spent my afternoon. Decent day in my books. Love working on vehicles. I should go to college for an auto mechanics course.
