Have 80k miles on my car and it's running fine, but have decided to replace the plugs. Has anyone installed the Bosch Iridium plugs, part # 9652? After a $2/plug rebate from Bosch, they are comparable in price with the OE replacement plug # FR8DPP33+, the SP type. Here's a link to the Bosch website: Spark Plugs

If anyone has experience, good or bad, with any specific plug type please chime in. I don't have a specific brand preference, Bosch is one of the types referenced in the owner's manual, along with NGK.
