Ranking the Best Spark Plugs for Fuel Efficiency in 2024
Optimize fuel economy and reduce emissions with the right spark plugs.
This concise guide highlights top spark plugs for fuel efficiency in 2024, with quick buying tips.
Top Fuel-Efficient Spark Plugs
Iridium spark plugs: highest longevity and consistent spark for improved MPG.
Platinum spark plugs: cost-effective, reliable gains in fuel efficiency.
Copper-core plugs: strong conductivity for older engines but shorter life.
OEM-recommended plugs: best fit and heat range match for optimal combustion.
How to Choose the Best Spark Plugs
Match heat range and gap to your engine specification for maximum efficiency.
Prefer iridium or platinum for direct-injection and turbocharged engines.
Consider longevity: longer-lasting plugs maintain peak fuel economy longer.
Check compatibility: plug thread size and reach must match OEM specs.
Regular inspection: fouling or wear reduces MPG—replace per service interval.
Quick Comparison (2024 Picks)
1) Iridium premium: best for long-term fuel savings.
2) Platinum performance: balance of cost and efficiency.
3) OEM-grade: safest choice for manufacturer-tuned economy.
Buying Tips & Maintenance
Pre-gap only if required; many plugs come pre-gapped to OEM specs.
Use anti-seize only where recommended to avoid torque errors.
Replace in pairs or sets to keep cylinder performance even.
Inspect ignition coils and fuel system—spark plugs alone can't fix broader issues.
Keep a maintenance log to measure MPG gains after plug changes.
