had occasional issues getting car to fire when starting, but nothing serious.
I got these because they are 1-step colder than factory for greater knock prevention and more timing. The plugs take a bit longer to start the car than the stock plugs but once you're going they are real smooth and I don't notice a power difference but it is the piece of mind knowing that the tune can use more timing and have less knocking.
