Spark Plugs
I believe we are supposed to change out E70 spark plugs around 60k miles.

I know people think OEM which are Bosch platinum are better.
$8.56
More Information for BOSCH ZR5TPP33S

I have been told Iridium last longer. They have these two on rock auto.
$6.01
More Information for DENSO 5356
$9.19
More Information for DENSO 3501

It says the $9.19 Denso iridium lasts 100k miles. I think the Bosch platinum last around 60k miles. Anyone know how long the regular $6.01 Denso iridiums last?
Any thoughts on what is preferred?
