what diameter is the thread and length of thread for e368 spark plug. must be in metric readings

Sorry,i js bought this for my friend.

can these work on 2015 corolla

if you are unsure of fitment OR don't trust the fitment guides on amazon, you can look up exact fitment on E3 website... e3sparkplugs.com ... they have fitment for nearly all applications...

Is it strongly recommended that I install new ignition coils along with the new e3 spark plugs? Or would keeping my stock ignition coils work fine ?

All the customers that I sold E3 spark plugs never change the coils. It should be ok. Just make sure you check for the fitment on the plugs vs you vehicle. e3sparkplugs.com

can i use these to replace 2006 is250 spark plugs? if so, do they just screw in like any other sparkplug?

according to the e3 website, that is the correct plug for your car. They screw in just line normal plugs. YOu don't have to gap them. http://shop.e3sparkplugs.com/automotive-spark-plugs/e3.68-spark-plug/?sd=TWpBd05ueE1aWGgxYzN4SlV6STFNQ0I4TWk0MVRDQWdWallnSUVaSklDQW9NalJXS1NBZ1JFOUlReUFnTkVkU1JsTkZJQ0FnfEl6bzllRXN5VVRoUlhqWjZmVnBEY2c9PQ==
