Infiniti Genuine vs Aftermarket Parts Guide: Making the Right Choice for Your Luxury Ride
You’re staring at your Infiniti Q50 in the repair shop, weighing the cost of a genuine Infiniti part against a cheaper aftermarket option—and you’re wondering if the premium price is really worth it.
It’s a decision every Infiniti owner faces eventually. Whether you’re replacing brake pads on your QX60, upgrading suspension components on your Q50, or fixing a damaged mirror on your QX80, the genuine vs aftermarket debate matters. Your Infiniti represents a significant investment in Japanese luxury engineering, and the parts you choose affect performance, safety, and long-term value.
This guide breaks down everything you need to know about Infiniti genuine parts versus aftermarket alternatives—from quality differences to warranty implications, real-world owner experiences, and when you can safely save money.
TL;DR (Too Long; Didn’t Read)

What Are Genuine Infiniti Parts?
Genuine Infiniti parts are components manufactured specifically for Infiniti vehicles, following the brand’s exact engineering specifications . Here’s what makes them different:
Precision Engineering
Every genuine part is designed to match your Infiniti’s original components. These parts undergo rigorous quality control and testing to meet Infiniti’s performance and safety standards . From engine components to interior trim, genuine parts are engineered to work in perfect harmony with your vehicle’s systems.
Guaranteed Fit
Unlike generic parts designed to “work” with multiple makes and models, genuine Infiniti parts are crafted for your specific vehicle model and year . This eliminates the trial-and-error process often associated with aftermarket alternatives and ensures proper installation .
Warranty Coverage
Genuine Infiniti parts come with a manufacturer’s warranty, and using them won’t void your existing factory warranty . If a genuine part fails prematurely, you’re protected by Infiniti’s commitment to quality .
Higher Cost, Better Value
Genuine parts typically cost 15%-25% more than aftermarket options . However, they often provide better long-term value through superior durability, proper fit, and reduced risk of recurring problems. A 2024 Consumer Reports study ranked Infiniti’s 10-year repair costs at $8,420—higher than mainstream brands like Toyota ($5,050) but lower than many luxury competitors .
Understanding Aftermarket Parts
Aftermarket parts are manufactured by companies other than Infiniti. They’re designed to fit a range of vehicles, not just your specific Infiniti model . Here’s what you need to know:
The Price Appeal
Aftermarket parts are generally less expensive than genuine options . This makes them attractive for budget-conscious owners or for repairs on older vehicles where the original part’s premium price may be hard to justify .
The Quality Spectrum
Aftermarket quality varies wildly. Some aftermarket manufacturers produce excellent components that perform comparably to genuine parts. Others cut corners, leading to inconsistent performance, improper fit, or reduced durability .
Real-World Experience: Suspension
One Infiniti G37x owner faced the genuine vs aftermarket choice when replacing worn struts and shocks. Aftermarket KYB assemblies were about 40% cheaper than genuine Infiniti parts. Forum feedback suggested the KYB parts offered a good ride quality—firm enough for sporty handling without being harsh . However, the owner noted that for critical components like the steering rack and wheel bearings, they were leaning toward genuine parts for reliability .
Real-World Experience: Brakes
An Infiniti Q50 owner discovered that aftermarket brake hardware kits didn’t include the same backing shims that came with genuine kits. The extra shims in the genuine kit help with pad alignment and noise reduction, while aftermarket kits included pins and clips but omitted the shims . The owner ultimately chose high-quality aftermarket pads (Akebono) while keeping genuine shims and pins—a hybrid approach .
Genuine vs Aftermarket: A Detailed Comparison
| Factor | Genuine Infiniti Parts | Aftermarket Parts |
|---|---|---|
| Fit and Compatibility | Perfect fit for your specific model | Varies; may require modifications |
| Quality and Testing | Rigorous testing to Infiniti standards | Quality varies widely by manufacturer |
| Price | 15%-25% higher than aftermarket | Generally cheaper, sometimes significantly |
| Warranty | Covered by manufacturer warranty; preserves factory warranty | May void factory warranty for related repairs |
| Performance | Matches original vehicle performance | May differ; some perform well, others don’t |
| Availability | Through Infiniti dealers and authorized retailers | Widely available from many sources |
| Safety | Meets Infiniti safety standards | Varies; safety not guaranteed |
The Warranty Question: Why It Matters
One of the most significant differences between genuine and aftermarket parts is warranty protection.
Preserving Your Factory Warranty
Using genuine Infiniti parts helps protect your vehicle’s existing warranty coverage. Many warranties require authentic manufacturer parts for covered repairs, and using aftermarket alternatives could void your protection for related systems .
The Chroming Warning
Infiniti has issued technical service bulletins warning that aftermarket chroming of genuine Infiniti alloy wheels is “strongly discouraged.” The chroming process can change the alloy’s heat treatment, degrade durability and safety, and will likely result in denial of any warranty claim . This illustrates how even modifying genuine parts with aftermarket processes can void your coverage.
Genuine Parts Have Their Own Warranty
If a genuine Infiniti part fails prematurely, you’re covered by the manufacturer’s warranty. This provides additional peace of mind that aftermarket parts don’t always offer .
The “Value Advantage” Option: An In-Between Choice
Infiniti offers what they call “Value Advantage” parts. According to forum insights, these are not simply aftermarket parts—they come from the same manufacturers who make the original equipment (OE) versions. The difference is that the manufacturer handles the quality control, leaving Infiniti off the hook for some expenses. They remain ISO-qualified parts from Infiniti-qualified manufacturers .
Bottom line: Value Advantage parts are a genuine-adjacent option at a lower price point, though designs may differ slightly from original parts in some cases.
When to Choose Genuine Parts (and When Aftermarket Is OK)
Choose Genuine Parts For:
Safety-Critical Systems
Brakes, airbags, steering, suspension, and electronic safety systems require the precision and reliability that only genuine parts can ensure . Compromising here puts you and your passengers at risk.
Warranty-Dependent Repairs
If your vehicle is still under factory warranty, using aftermarket parts on covered systems could void your coverage .
Complex Electronic Components
Infiniti’s sophisticated electronics—like the INFINITI InTouch™ Infotainment System, ProPILOT Assist™ Driver Assistance, and sensor systems—require components that meet exact specifications. Aftermarket electronics may not communicate properly with your vehicle’s systems.
Preserving Vehicle Value
If you plan to sell your Infiniti, using genuine parts helps maintain resale value and reassures potential buyers .
Aftermarket Parts Can Be Reasonable For:
Older Vehicles
For an older Infiniti with significant mileage, the cost of genuine parts may exceed the vehicle’s value. High-quality aftermarket parts from reputable brands can be a sensible choice .
Cosmetic or Non-Critical Components
For items like interior trim, floor mats, or minor body panels, aftermarket options may be acceptable if quality is adequate.
Performance Upgrades
Some aftermarket manufacturers offer performance-oriented parts that exceed stock specifications. If you’re modifying your Infiniti for performance (like upgrading brakes with Akebono aftermarket pads), ensure you’re choosing reputable brands .
Buying Tips: Where and How to Purchase
Buy from Reputable Sources
Infiniti Dealers: The safest option for genuine parts, with expert support and warranty protection.
Authorized Online Retailers: Some Infiniti dealers offer online parts sales with competitive pricing. Forum members have recommended Infiniti of Nashua and Infiniti of Austin for discounted genuine parts .
Beware of InfinitiPartsDeal.com: A forum PSA warns that InfinitiPartsDeal.com (and associated sites) has poor customer service, difficult returns, and may string customers along until return windows expire. Despite offering genuine parts, the experience can be frustrating and costly . Safer alternatives include Amayama Japan and Partsouq Dubai for OEM-certified parts .
Check Reviews
Before ordering online, research the seller. Look for real owner experiences on forums like NICOclub or Infiniti Q50 Forum .
Consider the “Value Advantage” Option
Ask your Infiniti dealer about “Value Advantage” parts—they offer genuine-adjacent quality at a lower price point .
