Installing the Delco Gold R45s was straightforward. I made sure to:
- Clean the spark plug wells before installation.

- Check the gap and adjust it if necessary, though the plugs generally come pre-gapped.
Following these steps helped me avoid common mistakes and ensured optimal performance.
Performance and Longevity
After using the Gold R45s for several thousand miles, I noticed consistent engine smoothness and fuel efficiency. The durability lived up to the claims as they maintained their performance without fouling or misfires.
Price and Value
While these spark plugs were a bit pricier than budget options, the performance boost and longer lifespan made them worth the investment in my opinion.
