So far so good
In a nutshell they are a solid well made plug you can depend on to not miss fire like the off brands do. Been using them for decades for a reason.

A Spark of Genius (Without the Drama)
Ah, the platinum spark plugs and autolite—a marvel of engineering that arrived on time (shocking, I know). These plugs worked as expected, delivering reliable performance without any unexpected sparks of creativity. Truly, they are the unsung heroes of the automotive world, flawlessly igniting engines while refusing to ignite any excitement. The auto light? It’s as bright and functional as it needs to be—no flair, no pizzazz, just cold hard functionality. If you’re looking for a set of spark plugs and a light that scream “I do my job and nothing more,” this is the dream team. Bonus points for being delivered promptly, because who doesn’t love punctual parts?

35/1000 not 50/1000
These plugs are gapped at 35/1000th from the factory. Ford Fusion calls for 50/1000th. Make sure to check and regap if using on a Ford Fusion.

Not the same product.
Not the same as the last time I ordered. The spark plugs was not gapped. Would not work in my 2019 GMC Terrain.
