did autolite spark plugs screw up coil or coils ??

[YarisSedan]

Well if you look one spark plug cost 5.95 and another spark plug cost 20-28 dollars depending where you purchase them there has to be a difference. One is designed by a oe manufacture for ford and one is a oe manufacture for toyota. Me personally i would rather get the part from toyota. From my experience autolite starters, and autolight altenators and batterys are pieces of junk. My friend works at kragens and he says he gets a rediculiouse amount of warrenty returns on them. So i would not use a spark plug made by that particular brand in my vehicle. Either denso or ngk is all i would use. All we know is many users have had no problems with coil failures and users that have had coil failures reported using a alternative plug. Search all the posts for coil failures you will find what i am saying has some sense to it. I remember last month if orget the brand but it was suposily some high performance plug some user had problems with failed coil as well.

From my own personally experience the only coils i have changed on cars when i removed the plug it was either extremely worn out or a different type of plug.
