Frequently Asked Questions (FAQs)
1. What spark plugs increase horsepower?
Copper spark plugs, known for their better conductivity and ability to run cooler, can increase horsepower in performance driving situations. They are commonly found in turbocharged engines, engines with higher compression ratios, and older vehicles with distributor-based ignition systems.
Copper spark plugs offer the best performance due to their excellent electrical conductivity and ability to run cooler. While iridium spark plugs deliver better performance than platinum, they can be more expensive.
3. Do racing spark plugs make a difference?
Yes, racing spark plugs are designed to withstand the high-power and high-performance demands of racing engines. They are built to dissipate heat and deliver maximum engine power, making a significant difference in performance under challenging racing conditions.
4. Will a hotter spark plug make more power?
No, using a hotter spark plug will not result in more power. A hotter plug simply runs hotter, but it does not provide any additional power. Similarly, using a spark plug that is too cold will not increase power either.
5. Will spark plugs increase acceleration?
Yes, replacing spark plugs and wires can improve acceleration and overall performance. By ensuring a smoother and faster engine operation, spark plugs contribute to better acceleration and may even lead to improved fuel economy.
6. Why are NGK spark plugs better?
NGK spark plugs are considered better due to their trivalent plating, which provides corrosion resistance against moisture and chemicals. The plating also acts as a release agent during spark plug removal, making NGK spark plugs a reliable choice.
7. Are higher quality spark plugs worth it?
Yes, higher quality spark plugs are worth it as they not only meet but often exceed original equipment specifications. When having spark plugs replaced, it is recommended to insist on high-quality options to ensure optimal performance and longevity.
8. Does gapping spark plugs increase horsepower?
Side-gapping or "side-filing" spark plugs can potentially increase power and mileage in racing or extreme high-performance engines. This technique improves flame kernel efficiency and propagation through the combustion chamber, resulting in enhanced performance.
