Spark Plugs

I just changed out mine at 67k and yes they do look the same plus the factory gaps were pretty big 040-045. I used NGK 6509 gapped them .030 and the truck feels better.

The thing I'm kicking myself for is I didn't use any dielectric grease on the coil or plug boots. I would just change the wires next time after another 50k anyway, but perhaps it's a better job to use the stuff and to seal the coils up too.

Did you guys use dielectric grease?

I did, not that I think it's critical but doesn't hurt.
