Get them from Auto One for around $55 for 6. They are gapped at 1.1 (BA factory gap) but I just gap them down to 0.8.Performance has been great and I can't see any down sides. If they are good enough for NASCAR, they are good enough for me!It should be known though that depending on your tune and Kms driven, you should probably look at changing plugs more often than what you might think. For a highly tuned car, I would be changing at least every 12 months if the car is driven regularly - personally I change mine every 6 months, but that's probably because I'm a little pedantic!
