Currently at 30K and getting ready for the plug change
Listened to the voices in this thread and got my plugs at RockAuto with the 5% off coupon code.
They were shown as "not-in-stock / 3 days delay"... Placed my order and received shipping confirmation 1 day later.
I bit the bullet and ordered only 8.. No problems here.. No wrong plugs werent sent
Would purchase from RockAuto again in the future.
