4 x Bosch Super Spark Plugs #WR8AC - the packaging may vary as Bosch changes it all the time - the current packaging no longer says "Super" but it's the same plug. If you are looking for the "Super Plus" - these are the same plug but without the tapered electrode. Bosch no longer makes this size plug in the "Super Plus" line which has been mostly discontinued.
