Expect to pay roughly $200 to $400 for a spark plug replacement at a shop, depending on the model year and local labor rates. DIY costs can be lower if you supply the parts yourself. Prices can also vary if ignition coils or wires need replacement.
The Acura ILX has used more than one four-cylinder engine during its production run, leading to some variation in plugs and labor. Spark plugs are typically iridium or platinum types with longer service intervals, and labor times usually fall in the 1–2 hour range. Regional labor rates and shop policies also influence the final bill. The sections below break down typical costs, engine-era differences, and options for do-it-yourselfers.
Cost factors and typical ranges
Before listing the main price components, note that the total you pay depends on parts quality, labor rates, and any ancillary services like coil replacement or misfire diagnostics.
- Parts: Four spark plugs at about $12–$25 each, depending on brand and whether they’re iridium/platinum or copper. Typical parts total: $48–$100.
- Labor: Usually 1–2 hours at a shop rate of roughly $75–$150 per hour. Typical labor total: $75–$300.
- Taxes, disposal fees, and any shop fees can add a small amount on top of the base price, often $5–$20.
If ignition coils or associated wires are worn or damaged, or if a more complex engine variant is involved, the cost can rise beyond the baseline figures above.
Engine variants and year ranges
The ILX used different engines over the years, which can influence plug type and replacement considerations. Below are general estimates by engine type, noting that actual prices vary by shop and region.
2.0L engine (2013–2015 ILX)
For the 2.0L ILX, parts are typically in the lower end of the range, and labor times are similar to other four-cylinder replacements. Expect a total in the roughly $110–$270 range before tax and fees, assuming no coil or wire issues.
2.4L engine (2016–2020 ILX)
The 2.4L variant may incur slightly higher parts costs and similar labor times. Typical totals are in the approximate $150–$290 range, with some shops charging more in areas with higher labor rates.
DIY vs professional service
Do-it-yourself replacement can substantially reduce the cost to just parts and any tools you don’t already own. Here’s what to consider before you start.
- DIY parts cost: Four spark plugs typically run about $20–$60 total if you choose inexpensive copper plugs, or $40–$100+ for higher-quality iridium/platinum plugs.
- Tools and safety: You’ll need basic hand tools, a torque wrench, and a manufacturer-recommended spark plug socket. Coil-on-plug systems require care to avoid damaging coils.
- Time and risk: For a competent DIYer, expect 1–2 hours. Rushing or cross-threading plugs can lead to further repairs.
If you’re not comfortable with the task or you encounter difficult-to-remove plugs or faulty coils, a professional service is advisable to avoid cross-thread damage or misfires.
DIY replacement steps (general outline)
If you plan to do it yourself, here’s a high-level sequence. Always consult your owner's manual or a service guide for model-specific torque specs and procedure.
- Disconnect the negative battery terminal to prevent electrical shorts.
- Remove the engine cover (if equipped) and locate the ignition coils over each plug.
- Carefully unplug each coil pack, then remove the coil with the appropriate socket.
- Clean the plug wells, inspect coil boots, and install new spark plugs to the specified torque.
- Reinstall coils, reconnect wiring, and reattach the engine cover. Reconnect the battery and clear any codes if needed.
Note: Use the recommended torque specification for your engine variant, and replace any worn coils or boots if they show signs of damage. Dispose of old plugs per local guidelines.
Summary
For most Acura ILX models, spark plug replacement at a shop typically lands in the $200–$400 range, with parts around $50–$100 and labor $75–$300 depending on the engine variant and local rates. The 2.0L and 2.4L engines have similar labor times, but parts costs can differ slightly. Doing it yourself can cut costs further to roughly the parts price plus tools and time. Always verify current pricing with local shops, as rates and availability change with location and demand.

How much should I pay to have spark plugs replaced?
Spark plug replacement typically costs between $100 and $250+ for a standard vehicle. This includes both parts and labor. The final cost depends on the type of spark plugs used, the number of cylinders, and how difficult it is to access the plugs in your engine. High-performance or imported vehicles cost more.

What kills spark plugs quickly?
Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail. In addition, if the cooling system isn't functioning correctly, it can cause the engine and spark plugs to overheat. This overheating can lead to the spark plug's electrode wearing out faster.
