Great product, engine runs smooth, great performance.

### ⭐⭐⭐⭐⭐ Review
*by B***N on 7 June 2025*

The gap wasn't 0.044. Its was closer to 0.041. That being said, the stock plugs I pulled out measured 0.042. Rather than mess around trying to regap 16 spark plugs perfectly I just installed them as is. I changed the plugs at 144 000km and notice almost no difference in sound or driving. They came well protected. These plugs are kind of expensive. I bought them for $250 Ca and their price seems to just keep going up. The drivers side on my 2018 ram 1500 sucked to do, even with the swivel socket.
