Yeah I own and operate an auto repair facility and refuse to use Bosch plugs because I’ve had a lot of issues with them in the past. Misfires mostly.

Cons: misfires

I've heard for many decades how bad Bosch spark plugs are and I figured the coils would be just as bad, if not worse.

Cons: bad quality
