Rooting thru my collection of misc parts and came across 4 spark plug boxes. Opened, but plugs never used. First question to self was why I had only 4 when the car is a factory -6. Second, upon closer examination, was why they are 2 different types.
Bosch Platinum WR5DP 0.6mm gap and Bosch Platinum WR8DP 0.9mm gap.
I suppose I could pull the plugs that are in the car now (been at least 5 years..) but that wouldn't answer which is the correct one.
Anyone else using these?
