Spark plug crush washer direction
I got a set of Autolite APP985 that came with crush washers. One side is flat and one is tapered. Which side goes toward the plug screw base? The NGK's that came out just have a flat washer so they are no help.
Current: 2016 Ram 1500 Sport - Past: 05 Wrangler LJ, 90 and 92 Trackers and 98 Wrangler SE
i am pretty sure the tapered seat goes towards the cylinder head.
