Comparison and Buying Insights

Choosing the best spark plugs for your Camaro SS depends primarily on your engine generation (LS or LT) and how you use the car.

For Stock/Daily Drivers (Prioritizing Longevity):
If you have a stock Gen 5 (LS3/L99) or Gen 6 (LT1), focus on the Platinum or standard Iridium options. The NGK G-Power Platinum (TR5GP) or the A-Premium Iridium & Platinum plugs offer significantly extended mileage intervals (often 60k+ miles) compared to copper plugs, meaning less time spent wrenching.

For Modified Engines (Prioritizing Performance and Heat Management):
If your Camaro has bolt-ons, a tune, or forced induction, heat management becomes critical. You need a colder plug. The NGK Iridium IX Spark Plug TR6IX is the consensus choice here. The ‘6’ heat range helps prevent detonation when running aggressive timing or boost, though you should confirm the correct gap and heat range with your tuner.

The Copper Advantage:
For a strictly stock LS that you don’t mind tuning up frequently, the NGK V-Power TR5 (Copper) plugs offer the highest conductivity and a very strong, immediate spark, all for a fraction of the cost of iridium. They are excellent for restoring factory feel.

Don’t Forget the Wires:
If you have headers, your factory wires are likely melting slowly. Pairing performance plugs with high-quality wires like the MSD 32819 Super Conductor Set ensures that all the energy generated by the coils actually reaches the spark plug tip.

FAQs About the Best Spark Plugs for Camaro SS

What heat range spark plug should I use in my Camaro SS?

The heat range is critical and depends on your engine’s modifications. Stock LS3/L99 (Gen 5) and LT1 (Gen 6) engines typically use a standard heat range (like NGK’s TR5 or equivalent). If you have added forced induction, significant compression, or a highly aggressive tune, you should move to a colder plug, such as the NGK TR6IX. A colder plug transfers heat away from the tip faster, preventing dangerous pre-ignition.

What is the recommended gap for a Camaro SS spark plug?

The factory gap for most LS engines is usually between 0.040 and 0.050 inches, depending on the year. Modern Gen 6 (LT1) plugs often specify 0.040 inches. However, if you are running a supercharger, turbocharger, or a custom tune, your tuner will likely recommend closing the spark plug gap down (e.g., to 0.030–0.035 inches) to prevent “spark blow out” under high cylinder pressure. Always check your service manual or with your tuner.

How often should I replace my Camaro SS spark plugs?

This depends entirely on the plug material:
– Copper: Every 30,000 to 40,000 miles.
– Platinum: Every 60,000 to 80,000 miles.
– Iridium: Every 80,000 to 100,000 miles.
If you heavily track or race the car, it’s wise to inspect and potentially replace even Iridium plugs more frequently.

Can I run a colder plug like the TR6 in a stock Camaro SS?

Yes, you can, but it’s generally not recommended. A colder plug in a stock, daily-driven LS engine may operate below its optimal temperature range, which can lead to increased carbon fouling, especially during low-speed driving or idling. Camaro SS spark plug performance is best optimized by matching the plug to the engine’s power level and thermal load.

Is NGK better than AC Delco for the Camaro SS?

While AC Delco is the GM original equipment supplier, NGK is widely recognized in the performance community for superior consistency and quality control, especially in their Iridium and Platinum offerings. Many aftermarket tuners exclusively recommend NGK spark plugs for LS engine performance upgrades due to their reliable heat ranges and construction.

Do I need new spark plug wires when replacing the plugs on my LS3/L99?

If your car is over 60,000 miles old or if you have installed long-tube headers, replacing the wires is highly recommended. Wires degrade over time and heat exposure. Upgrading to a low-resistance wire set (like the MSD Super Conductors) ensures the coils deliver maximum energy to your new high-performance Best Spark Plugs For Camaro SS.
