Bosch 4 plugs?
Anyone ever upgraded the spark plugs? I was told that Bosch has a 4 prong plug that burns more efficiently and could help w/mileage gains. I asked a service tech at the dealer and he recommended NOT changing the plugs from the stock because the motor was set to certain specs. and this could throw off these specs. Any suggestions would be greatly appreciated!

I used them in mine when I recently changed the rocker arms and added headers. I don't know if they made any improvements but I don't have any complaints. There was an article in the last few months in one of the car magazines where they used these plugs and new plug wires and showed about a 5 to 10 h.p. gain (going from memory here) on the dyno.
If your plugs are old it might not hurt to upgrade the plugs and wires at the same time.

I used them in my car. I don't know if I got an "improvement" with them but I don't have any negative issues. Kaley
