Valley olds is an unknown quantity at this point
To be honest, I am not really a fan of Bosch spark plugs. A quick google search will show many people's negative opinions about them. I went for the NGK Iridiums. I don't buy spark plugs every day, they are only four, might as well go for the best NGK has to offer (I think).

If you want a plug that conducts more electricity, go for copper.

If you want a long life plug, go for platinum.

If you want a bit of both, go for iridium.

You will not really see much, if any, of a performance improvement with spark plugs though.
