How much does a fuel injector cost for a Lexus?
For a Lexus, a single fuel injector typically costs about $60 to $350 for aftermarket parts, and roughly $150 to $400 for OEM/Denso/Lexus units. A complete set for most engines runs around $900 to $2,400, depending on engine type and supplier.
What affects the price
The price you pay for Lexus fuel injectors is driven by several factors, including brand, injector type, and engine configuration. The following points outline the main variables you’ll encounter when shopping.
- Type of injector: Port‑fuel injectors are generally cheaper than direct‑injection units, which operate at higher pressures and require tighter tolerances.
- OEM vs aftermarket: Genuine Lexus/Denso parts tend to cost more but are designed to match the exact specifications of your engine, while aftermarket injectors can be cheaper and offer compatibility from third‑party brands.
- Engine configuration: Four‑cylinder engines use four injectors, while most V6 Lexus engines use six. Price per injector often scales with injector type and precision required.
- New vs remanufactured/refurbished: Remanufactured injectors are typically cheaper but may carry shorter warranty periods or fewer guarantees than new units.
- Region and retailer: Taxes, shipping, core charges, and retailer pricing strategies can influence the final price.
When budgeting, consider not only the injector price but also the potential cost of related parts and services, such as O‑rings, seals, fuel rail service, and labor if you’re having a shop handle the replacement.
Typical price ranges by engine type
The following ranges reflect common configurations found in many Lexus models and illustrate how price per injector can vary by engine design.
- Four‑cylinder Lexus engines: aftermarket injectors ≈ $60–$180 each; OEM ≈ $120–$260 each. Full set ≈ $240–$1,040 aftermarket or $480–$1,560 OEM.
- V6 Lexus engines (commonly 3.5L with six injectors): aftermarket injectors ≈ $90–$180 each; OEM ≈ $180–$350 each. Full set ≈ $540–$1,080 aftermarket or $1,080–$2,100 OEM.
- Direct‑injection/D‑4S variants (higher performance or newer models): injectors ≈ $200–$350 each; OEM ≈ $250–$500 each. Full set ≈ $1,200–$1,750 aftermarket or $1,500–$3,000 OEM.
Prices above are typical ranges observed across major retailers and OEM suppliers in 2024–2025. Exact pricing depends on your specific Lexus model, production year, and the retailer.
Where to buy and how to budget
Shop for injectors through multiple channels to compare prices and warranties. The options listed below are common sources, each with its own pros and cons.
- Authorized Lexus/Toyota dealers: highest reliability and exact fit, often with solid warranties but higher upfront cost.
- OEM parts distributors (Denso/Hitachi suppliers): reliable, brand‑matched injectors that may be slightly cheaper than in‑dealer pricing.
- Reputable aftermarket retailers: can offer lower prices and occasional promotions; verify compatibility with your model and confirm return policies.
- Remanufactured or rebuilt injectors: lowest upfront cost but variable warranty and longer risk profile; ensure they include O‑rings and proper testing.
When budgeting, account for additional costs such as new O‑rings, seals, fuel rail service if needed, a possible fuel pressure test, and labor fees if you’re having a shop replace the injectors.
Installation considerations
Replacing fuel injectors is a moderately complex job that may require special tools and professional expertise. Consider the following to ensure a proper replacement and long‑term reliability.
Key considerations include ensuring a clean fuel system, replacing all injectors if one shows failure symptoms, using fresh O‑rings and seals, and verifying fuel pressure and injector operation after installation. A misdiagnosis or improper seating can lead to leaks, poor spray patterns, or engine misfires.
Summary
Injector pricing for Lexus vehicles varies widely by engine type, injector design, and supplier. Plan for roughly $60–$350 per injector for aftermarket parts and $150–$400 for OEM units, with full engine sets typically ranging from about $900 to $2,400. Always confirm compatibility with your exact model and year, compare dealer vs aftermarket options, and factor in installation costs and any related service needs.
