You rely on your Camry to be smooth, efficient and dependable. Choosing the right spark plugs affects fuel economy, throttle response and long-term reliability.
Replacing worn plugs with the correct type can restore performance, reduce misfires and save you money on fuel and repairs. Below you’ll find options that fit the 2.5L L4 engines used in 2017 Camry models, from inexpensive OEM-compatible replacements to high-end iridium units designed for longer life and better ignition.
This article covers the 2017 Toyota Camry 2.5L I4 (2AR-FE) engine only.
- V6 3.5L owners (2GR-FE engine): You need a different plug — DENSO FK20HR11 (OEM part #90919-01247). The plugs listed below will not fit your engine.
- Camry Hybrid owners (2AR-FXE engine): Your engine requires DENSO FK16HR-A8 (OEM part #90919-01259). Installing a non-hybrid plug in the Hybrid can cause ignition issues. Do not use the SK16HR11 listed below.
If you are unsure of your engine, check your owner’s manual or the sticker under the hood.

How We Chose These Spark Plugs
You want parts that fit, last and perform. We prioritized: compatibility with the 2017 Camry 2.5L L4 and 2AR-FE engines; electrode material (iridium and platinum for longevity and consistent spark); OEM-equivalent part numbers when available; verified customer ratings and real-world feedback; price/value balance for a full 4-plug set; and features like recommended gap and manufacturer service intervals. We also weighed brand reputation (DENSO, NGK, OEM equivalents), ease of installation for a DIYer, and whether the plug addresses common Camry issues like misfires or rough idle.
A-Premium Iridium Platinum Spark Plugs (Pack of 4)

For everyday commuting you’ll notice steady idling and clean starts; for longer highway trips they help maintain consistent combustion and fuel efficiency. They’re also the sort of upgrade you install before a road trip or when you want smoother cold starts.

FAQ
How Do I Choose The Right Spark Plugs For My 2017 Toyota Camry?
First, identify your exact engine — and confirm this article applies to you. This guide covers the 2.5L I4 (2AR-FE) engine only. If you own the V6 3.5L (2GR-FE), you need DENSO FK20HR11 (OEM #90919-01247). If you own the Camry Hybrid (2AR-FXE), you need DENSO FK16HR-A8 (OEM #90919-01259).
For the 2.5L I4, confirm the OEM part number or fitment. You should check compatibility with your vehicle by VIN or owner’s manual. The factory OEM plug is DENSO SK16HR11 (part #90919-01233). The OEM gap specified by Toyota for the 2AR-FE engine is 0.043 in. (1.1 mm). Aftermarket plugs in this article use pre-set gaps of 0.040″ or 0.044″ depending on the product — these are within acceptable range but are not the exact OEM spec. Always verify the gap listed for the specific plug you choose.
In terms of materials, iridium plugs typically give the longest life and most consistent spark, platinum is a good value compromise, and some hybrid applications list titanium or specific OEM types — so match the recommended type for your Camry. Also pay attention to the heat range and the manufacturer reputation; brands like Denso, NGK or genuine OEM replacements and well-reviewed aftermarket options tend to be more reliable.
Finally, watch for authentic packaging and OEM-equivalent markings to avoid counterfeit parts. The SK16HR11 part number in particular has documented counterfeits on Amazon — when purchasing, prefer listings fulfilled directly by Amazon.
Can I Install These Spark Plugs Myself And What Precautions Should I Take?
Yes, you can install them yourself if you have basic tools and patience, but take a few precautions. Work on a cool engine, remove coils carefully, and always hand-thread the plug first to avoid cross-threading. You will need a 5/8″ (16 mm) spark plug socket and an extension to reach all four plugs. Use a torque wrench and tighten to Toyota’s specified torque of approximately 13–18 ft-lb (18–25 N·m) on a cold engine — always confirm with your model-year service manual, as the exact spec can vary. Do not over-tighten. Many iridium/platinum plugs come with plated threads so you should not apply anti-seize unless the manufacturer explicitly says to; a light pea of dielectric grease in the ignition boot can help prevent moisture and boots sticking.
Verify or set the gap if the part requires it before installation, replace all plugs at the same time for consistent performance, and inspect ignition boots and coils while you’re in there. If you’re unsure, a quick shop install typically takes less than an hour and prevents costly mistakes.
How Often Should I Replace Spark Plugs And How Will I Know They’Re Failing?
Replacement interval depends on the plug type and your driving conditions. Toyota’s official maintenance schedule for the 2017 Camry 2.5L I4 (2AR-FE) specifies spark plug replacement at 120,000 miles — this applies to the genuine OEM DENSO SK16HR11 iridium plug. Aftermarket iridium plugs (DENSO Iridium TT, NGK Laser Iridium) are also rated up to 120,000 miles. Note that the NGK Iridium IX is rated for approximately 40,000–50,000 miles and should be replaced more frequently. Always follow the interval for the specific plug you install, and consult Toyota’s schedule in your owner’s manual.
You’ll know plugs are failing if you see a persistent check engine light with misfire codes (P0301, P0302, P0303, or P0304 for individual cylinders), rough idle, hesitation under acceleration, increased fuel consumption, or difficulty starting.
If a misfire continues after swapping plugs, inspect ignition coils, fuel and compression as the root cause may lie elsewhere. After installing new plugs, re-check for codes and confirm smooth idle and improved throttle response; if you ever doubt fitment or see unusual wear patterns, consult a mechanic so you don’t mask another issue.
