It sucks when you’ve got a budget to fit in and you want to find something that would be the best bang for the buck, but it’s impossible to narrow down the choices without spending hours (sometimes tens of hours) on research and reading the reviews on the best spark plugs.

We decided that it’s time for robots to do the hard work. Here’s how:

  1. With the help of Artificial Intelligence, we analyzed hundreds of thousands (no kidding) of reviews from verified owners on Amazon and reputable expert sources like Consumer Reports, The Wirecutter, PCmag, and many others.
  2. Every product got its own rating in each category (like “best something for horsepower”).
  3. We compiled lists of the best products in every category and created lists like the one you can see below
  4. We shared them with the public, so you guys could make informed decisions and save time.

For this article about the Best Spark Plugs For Horsepower we reviewed and evaluated more than 180+ spark plugss. The AI (artificial) selected only those that received the top award. Only winners are listed below. You can see the highest overall rating of each item and a comprehensive breakdown of its characteristics.
