Agreed, the plugs are 30k platinum plugs so they are quite a bit more than standard copper plugs which would be around that price. I checked on the water pumps, it's the same pump for MT and AT vehicles but they are often different and sometimes different prices. The pricing is sometimes different because of the features of the pump. A pump with additional ports is generally more expensive.
Yes, even though the date is long long ago I update pricing regularly! I do need to update for newer models since I am starting to get requests for those.
