I still have a supply of W8ACs, but you're right that Bosch now only
sells the resistor versions, WR8AC. Those are fine, and they make it
possible to switch to the non-resistor SP connectors, which I also
have in stock. I still use the old style, but using resistor plugs
means that you no longer need to worry about the resistor in the
connector opening up, since the SPs will get changed long before that
happens.
There's nothing wrong with the NGKs, but the Bosch plugs work
perfectly in our cars, so I've stuck with them rather than learn a
different system.
