Improved Engine Performance with Professional Spark Plugs

As a result of my tests, I determined that these spark plugs significantly enhance engine performance and fuel efficiency. The installation process was hassle-free and THE results were immediately noticeable. The only downside is the relatively high price point compared to other spark plugs on the market..

Pros
  • Improved engine performance, increased fuel efficiency
Cons
  • Higher price point than other options

Seems better made than what I replaced it with.

I accidentally tore the outer insulation on one of these wires when trying to get at the contact that snaps onto the spark plug. Took advice from a YouTuber he shouldn't have. After getting everything right (silicone lube and patience) I was able to verify that the terminal is 10x larger than this 454. Yes, it actually clamps and makes a good connection (who would have thought). Luckily when I ripped the outer insulation it didn't damage the fiberglass so I was able to hit it with heat shrink…

Pros
  • Spark Plugs and Wires
