How much plugs for Toyota Yaris?
Most Toyota Yaris models with four-cylinder engines use four spark plugs, while three-cylinder variants use three. A complete set of plugs typically costs roughly $8–$100 for parts, depending on the type, with labor costs added if you have a shop replace them.
This article breaks down the typical plug counts for common Yaris configurations and outlines current price ranges for spark plugs, helping you estimate replacement costs and shop around for parts.
Engine variants and spark plug counts
Engine configurations vary by market. The following breakdown covers common Yaris configurations you’re likely to encounter in recent years.
- 4-cylinder Yaris engines (for example, 1.0L/1.3L/1.5L variants in many regions) typically require 4 spark plugs.
- 3-cylinder Yaris engines (such as 1.0L and some regional 1.5L setups) typically require 3 spark plugs.
- Hybrid Yaris variants use a 1.5L three-cylinder Atkinson-cycle engine and typically have 3 spark plugs.
Note that exact counts can vary by market and engine code; always check the owner's manual or a VIN-specific parts fiche for your model.
Price ranges for spark plugs
Prices vary by plug type, brand, and retailer. The ranges below reflect typical pricing in many markets as of 2024–2025 and may differ regionally.
- Copper/standard spark plugs: about $2–5 per plug; roughly $8–20 for a four-pack.
- Platinum spark plugs: about $6–15 per plug; roughly $24–60 for a four-pack.
- Iridium spark plugs: about $12–25 per plug; roughly $48–100 for a four-pack.
- Toyota OEM or premium options: often $20–40 per plug; roughly $80–160 for a set, depending on the exact model.
Installation and labor costs vary by shop and location. A typical spark plug replacement for a non-turbo four-cylinder Yaris can range from about $120 to $250 at an independent shop, and more at a dealership, depending on labor rates and accessibility of the plugs.
Tips for buying and replacement
Before you buy, verify your engine type and the correct plug type for your specific Yaris. Use the gap specification in the owner's manual and ensure you install the plugs with the proper torque. If you're not comfortable doing the replacement yourself, consider a professional service to avoid cross-threading or misfiring.
Choosing the right plug type
In modern Toyotas, iridium or platinum tips are common for longevity. Avoid copper plugs on engines designed for longer-life plugs if you want to maximize service intervals. Always match the heat range and the recommended interval from Toyota for your engine code.
Summary
In summary, a Toyota Yaris typically has 3 or 4 spark plugs depending on whether the engine is three- or four-cylinder. Part prices vary widely by plug type, with copper plugs being the cheapest and iridium/platinum options offering longer life. Expect roughly $8–160 for the parts set, with labor adding to the total if you hire a shop. Always confirm your exact engine configuration and follow the manufacturer’s replacement interval for best results.
