- Not Always Compatible: I found that E3 spark plugs are not available for every vehicle model. It’s important to check compatibility before purchasing.
- Mixed Reviews on Power Gains: While I noticed smoother running and better fuel economy, I didn’t experience a significant increase in horsepower or acceleration.

They worked well for my daily driver, especially if you prioritize longevity and cleaner combustion.
