When it comes to personalizing your 10th Gen Honda Civic, rear side window louvers are a popular upgrade that blends sporty aesthetics with subtle functionality. Two brands stand out in this niche: Thenice and DLOVEG. Both promise to elevate your Civic’s exterior, but their approaches differ in design, compatibility, and value. This 3,000+ word guide dives deep into every detail—material quality, installation nuances, style options, and real-world performance—to help you decide which louvers deserve a spot on your vehicle.
Section 1: Compatibility – Which Brand Fits Your Civic?
1.1 DLOVEG: Sedan-Exclusive Precision
DLOVEG’s louvers are engineered exclusively for 2016–2021 Honda Civic Sedans, including the Si trim. The triangular shape mirrors the rear side windows of these models, ensuring a flush fit without gaps. However, the brand explicitly states that their product does not fit Civic Hatchbacks, limiting its appeal to sedan owners. This specificity minimizes installation headaches but restricts versatility.
1.2 Thenice: Dual Compatibility for Sedan and Hatchback
Thenice takes a broader approach, offering louvers compatible with both Sedan and Hatchback variants of the 10th Gen Civic (2016–2021). This inclusivity is rare in the aftermarket louver space, making Thenice a go-to for Hatchback owners seeking customization. Their design accounts for the Hatchback’s slightly different window contours, ensuring a seamless fit across body styles.
Key Takeaway:
- Choose DLOVEG if you own a Civic Sedan and prioritize a guaranteed, no-modification fit.
- Choose Thenice if you drive a Hatchback or want future-proof flexibility.
Section 2: Material Quality – Durability Under the Microscope
2.1 DLOVEG’s ABS Plastic Build
DLOVEG uses standard ABS plastic, praised for its lightweight yet rigid properties. The material resists cracks and deformation under normal conditions, and the glossy black finish adds a sleek, factory-like sheen. However, the product description lacks details about UV protection, raising questions about long-term fade resistance in sunny climates.
2.2 Thenice’s Enhanced ABS Formula
Thenice also relies on ABS plastic but emphasizes anti-corrosion and oxidation resistance, suggesting a higher-grade formulation. Their louvers include a UV-resistant coating to combat sun damage, a critical advantage for drivers in regions with harsh sunlight. Additionally, Thenice offers five color options (gloss black, matte black, carbon fiber, gunmetal, and chrome), allowing deeper customization compared to DLOVEG’s single bright-black finish.
Key Takeaway:
- DLOVEG suits budget-conscious buyers who want basic durability.
- Thenice invests in advanced material engineering for prolonged aesthetics.
Section 3: Design and Aesthetics – Style Showdown
3.1 DLOVEG’s Sporty Minimalism
DLOVEG’s louvers feature a three-slat design with a subtle upward curve, mimicking the Civic’s factory lines. The glossy finish complements OEM paint jobs, offering a clean, integrated look. While understated, the design lacks boldness, which might disappoint drivers seeking a standout aesthetic.
3.2 Thenice’s Bold Customization
Thenice leans into aggression with a five-slat layout and sharper angles, giving the Civic a tuner-inspired edge. The option to choose from five finishes—including carbon fiber—caters to diverse tastes. For example, a matte black louver pairs well with blacked-out trim, while carbon fiber accents align with performance-oriented builds. Thenice also encourages pairing louvers with matching handle and antenna covers, creating a cohesive exterior theme.
Key Takeaway:
- DLOVEG excels in subtle, OEM+ styling.
- Thenice dominates for drivers craving customization and visual impact.
Section 4: Installation – Tape, Heat, and Precision
4.1 DLOVEG’s Simplified Process
DLOVEG includes pre-cut 3M adhesive strips and straightforward instructions:
- Clean the window with alcohol.
- Apply the heated tape to the louver.
- Align and press firmly.
The process is beginner-friendly but demands precision—repositioning after adhesion weakens the bond. A 24-hour curing period is recommended before exposing the car to water.
4.2 Thenice’s Detailed Guidelines
Thenice’s installation mirrors DLOVEG’s but adds nuanced tips:
- Use a hair dryer to activate the adhesive’s stickiness before application.
- Press the louver for 1 full minute post-installation to ensure maximum contact.
- Avoid car washes for 48 hours (vs. DLOVEG’s 24), prioritizing bond strength over convenience.
Key Takeaway:
- Both brands rely on similar methods, but Thenice’s extended curing time suggests a stronger adhesive commitment.
Section 5: Functionality – Beyond Aesthetics
5.1 Aerodynamic Claims
Both brands assert their louvers reduce air resistance at high speeds, theoretically improving fuel efficiency and stability. However, independent testing on aftermarket louvers shows minimal impact on aerodynamics—often less than 1% MPG gains. The primary benefit remains aesthetic, though the slats may marginally deflect rain and debris.
5.2 Privacy and Sun Protection
The louvers’ angled slats reduce glare and UV exposure for rear passengers, a subtle functional perk. Thenice’s wider slats may offer slightly better coverage, though both brands perform similarly.
Key Takeaway:
- Manage expectations—louvers prioritize style over measurable performance gains.
Section 6: Price and Value – Breaking Down the Costs
6.1 DLOVEG’s Budget-Friendly Appeal
Priced lower than Thenice, DLOVEG targets cost-conscious buyers. The single-color option and sedan-only fitment keep production costs down, but the lack of a warranty (beyond Amazon’s return window) might deter some.
6.2 Thenice’s Premium Positioning
Thenice commands a higher price, justified by:
- 5 color options
- Hatchback compatibility
- UV-resistant coating
- 1-year manufacturer warranty
Key Takeaway:
- DLOVEG wins for affordability.
- Thenice justifies its premium with versatility and durability.
Section 7: Customer Support and Brand Reputation
7.1 DLOVEG’s Amazon-Centric Approach
DLOVEG operates primarily through Amazon, offering standard messaging support. Users report responsive but generic assistance, typical of third-party sellers.
7.2 Thenice’s Dedicated Ecosystem
Thenice promotes its branded storefront, showcasing Civic-specific accessories like spoilers and grilles. This focus suggests specialized expertise, and their warranty coverage adds peace of mind.
Key Takeaway:
- Thenice provides a more robust support network for enthusiasts invested in full builds.
Final Verdict: Which Louvers Should You Choose?
For Civic Sedan Owners on a Budget → DLOVEG
- Pros: Affordable, easy installation, OEM-like finish.
- Cons: Limited color options, no Hatchback support.
For Hatchback Drivers and Customization Fans → Thenice
- Pros: Multi-color choices, UV protection, Hatchback compatibility.
- Cons: Higher price, longer curing time.
