Hi, anyone using the above? did my oil change yesterday and comparing the original plug and the ecs one there the same thread but massive difference in hex size and strength. I got to say i didnt think its great for the job after it rounded slightly after a tiny turn with a 3/8 ratchet where as the original you can tighten it with anything. maybe i had it on a slight angle as i was on my back using axle stands but i didnt trust it and went back to the original which is 5 times cheaper.
