Honda spark plugs generally cost between about $2 and $25 per plug, depending on type and brand; a typical four-cylinder Honda uses four plugs, bringing the total parts cost to roughly $32–$100 before tax. If a shop does the replacement, labor adds about $60–$120 per hour, and the job usually takes 0.5–1 hour.
What influences the price
Prices vary based on the plug type (copper, platinum, iridium), brand (OEM versus aftermarket), your specific Honda model and year, and where you buy them. Modern Hondas often use iridium or platinum plugs designed for longer life, which shifts cost upward compared with older copper plugs.
Price ranges by plug type
Below are typical retail price ranges you’ll see for common Honda replacement options. Actual prices can vary by retailer, region, and whether you buy individual plugs or a multi-pack.
- Basic copper or copper-core plugs (older or budget options): $2–$6 per plug
- Standard platinum or platinum-tipped plugs (common modern aftermarket): $6–$12 per plug
- Iridium or dual-iridium plugs (longer life, higher performance): $12–$20 per plug
- OEM-spec or dealer-original plugs (Honda-branded or approved equivalents): $12–$25 per plug
In practice, a typical four-cylinder Honda replacement falls in the $32–$100 range for parts alone, depending on the exact type and brand chosen. Taxes, shipping, and any core charges can adjust the total price up.
Buying guidance and installation considerations
Choosing the right plug for your model
Always verify the correct part number for your vehicle’s engine by consulting the owner's manual, the service manual, or an authorized parts retailer. Cross-reference NGK, Denso, and Honda OEM listings to ensure the proper heat range and gap specifications. Some Hondas require specific torque values during installation, so follow torque specs and torque-wrench guidance to avoid damage or misfire.
Where to buy and how to save
Common options include auto parts retailers, dealer parts departments, and online shops. Savings can come from buying a multi-pack, waiting for sales, or choosing aftermarket plugs with similar performance to OEM. If you’re unsure about installation, a professional service can ensure the plugs are torqued to spec and correctly gapped (if applicable) to maintain optimal performance and fuel economy.
Summary
For Honda spark plugs, plan for roughly $2–$25 per plug depending on type and brand, with four plugs needed for a typical four-cylinder engine. Expect about $32–$100 for parts on a typical replacement, plus potential labor charges if handled by a shop. Always confirm the correct plug type for your specific model to ensure reliability and longevity.
