Comparison Insights: Choosing the Right Acura Integra Spark Plugs

When comparing these options for your Integra, the choice primarily boils down to two factors: how often you want to do maintenance and how modified your engine is.

For pure spark performance and the absolute best initial conductivity, NGK V-Power (Copper) is the budget champion but requires replacement every 30,000 miles. Copper is the most conductive material available for spark plugs.

If you prioritize longevity, look at the Platinum and Iridium options. The NGK G-Power (Platinum) plugs are an excellent middle ground offering 50,000-60,000 miles of reliable life at a reasonable cost.

However, Iridium plugs like the BKR7EIX are essential for modified or forced induction Integras because their extremely high melting point allows them to survive the intense heat and pressure that would quickly destroy copper or platinum plugs.

Finally, remember that the plugs are only as good as the wires feeding them. Complete kits like the Quaneguzy or NGK Wire & Plug combination offer the best overall value and convenience for a complete ignition system overhaul.

Complete FAQs About Top Spark Plugs for Acura Integra

Q1: What is the recommended spark plug gap for a stock Acura Integra B18 engine?
A: The standard recommended spark plug gap for most naturally aspirated Acura Integra B18 engines (including LS, GS, and GS-R) is typically 0.044 inches (1.1mm). Always confirm this specification in your specific owner’s manual, especially if you have a highly modified engine, as the required gap might be smaller.

Q2: Should I use copper, platinum, or iridium spark plugs in my Integra?
A: Copper (like NGK V-Power) offers the best conductivity for a strong spark but has the shortest life (30k miles). Platinum (G-Power) is a great balance of longevity and cost (50k-60k miles). Iridium (Iridium IX) offers maximum lifespan (80k+ miles) and high heat resistance, making it the superior choice for high-performance and modified engines.

Q3: How often should I replace my Acura Integra spark plugs?
A: Replacement intervals vary by material:
