Great spark plug replacement

This spark plug replacement is a great investment for anyone looking to improve their engine performance .As my tests showed it provides a strong and consistent spark that boosts power and fuel efficiency. The installation process was easy and straightforward, making it a hassle-free replacement part. However, the price may be slightly higher compared to other options in the market..

Pros
  • Strong and consistent spark, easy installation
Cons
  • Higher price compared to other options

Junk! Do Not Waste Your Money!

This product failed to work in my automotive application and even caused some serious issues after I put it to the test. The pros are non-existent, and the only thing that I can say is a con is that this product simply does not work. Do yourself a favor and stay away from this supposed ignition part..

Pros
  • Longer lifespan and improved performance compared to standard spark plugs.
Cons
  • May require a higher initial investment than standard spark plugs.

Gets strong after 40,000 miles

Update: They still work at 100,000 miles, although oddly Champion now says the 9002 doesn't fit my engine and recommends 9202. The specs look the same, except the minimum spacing for 9202 is closer but still .006 wider than my factory spec .031 (.037 for 9002 vs. .039 for 9002). I was sure last time that 9002 was recommended and you can manually adjust the gap with no visible damage. First Rating: I can't confirm the advertised 100,000 mile rating, but I haven't had any noticeable loss of power

Pros
  • V-finished ground electrode provides sharper spark focus
Cons
  • Modern
