3. Look at Heat Range Ratings

Spark plugs have heat ranges suited for different engines. A correct heat range keeps plugs from overheating or fouling. Too hot or too cold plugs reduce engine efficiency. Match heat range to your Challenger RT’s engine needs.

Customer feedback shows real-life performance and reliability. Look for plugs with high ratings and positive comments. Avoid products with many complaints about durability or fit. Reviews help find trusted spark plugs for your Challenger RT.

7. Consider Brand Reputation

Choose spark plugs from well-known brands for quality assurance. Established brands follow strict manufacturing standards. They offer better warranties and customer support. Trusted brands protect your engine and improve driving experience.

Conclusion

Choosing the right spark plugs for your Challenger RT can improve your car’s performance and fuel efficiency. Good spark plugs help your engine start faster and run smoother. They also last longer, saving you money on replacements. Copper, platinum, and iridium spark plugs each have their benefits.
