Looking to purchase a compression and leak down test set for my 06 Attak.

Is the plug size 10mm ? Threads reads 9.89mm on my caliper. What kit did you purchase ?
 
Yes, it is 10mm. I purchased this one. Worked very well to find the ring and valve leakage on a Phazer engine. Just don't screw the adapter into the head too tight because it will be a biatch to get out.
