Sometimes they don’t have the cardboard sleeves to protect it. so yeh, you always need to double check the gap. Don’t forget to anti-sieze the threads too. you wouldn’t want the plugs to get siezed in the block. this usually happens to high mileage cars though that never get a tune-up. --- _[View the full topic](https://forums.speedlife.net/t/gapping-spark-plugs/118922)._
