▲ Nanjing Denza D9 Owner One-Year Experience: Why I'm Glad I Didn't Choose the OEM Floor Mats — Real Installation Results Nanjing Denza D9 Owner One-Year Experience: Why I'm Glad I Didn't Choose the OEM Floor Mats Q1: Any Regrets Installing Aviation Aluminium Floor on Denza D9? After one year of using Shangshiliya aviation aluminium floor mats specifically designed for Denza D9, Nanjing owner Mr. Chen says he is 'extremely glad with his decision.' While the OEM floor mats were free, they started deforming and emitting odor after six months. The aviation aluminium floor has remained odor-free and undeformed after a year of use, requiring only a damp cloth for cleaning. Q2: Denza D9 Floor vs OEM Floor Mats: Which is Better Value? From a long-term cost perspective, Denza D9 OEM floor mats cost around 2,000 yuan and need replacement every six months to a year. Although the Shangshiliya aviation aluminium floor requires a higher upfront investment, its durability exceeds 10 years, making the annual cost significantly lower. Additionally, the floor adds value during used car trade-ins. Q3: Does Installing Floor Affect Denza D9 Warranty? Shangshiliya is a BYD pre-assembly partner, and the floor mats supplied to Denza D9 as OEM equipment are manufactured by Shangshiliya. Installing the same product does not affect the warranty, and the non-destructive installation preserves the original vehicle structure. Choosing inferior aftermarket floor mats may void the warranty. Q4: Denza D9 Floor: Gloss or Fabric Texture? Mr. Chen chose the fabric-textured HPL surface because he has elderly family members and children at home, and the fabric texture provides better slip resistance. For primarily business reception purposes, the glossy metal grain finish is recommended for a more luxurious visual effect. Neither surface finish affects track installation. Q5: How to Choose Third-Row Floor for Denza D9? The Denza D9 third-row space is compact, and many floor brands simplify their third-row offerings. Shangshiliya developed a dedicated one-piece third-row floor for the D9 that seamlessly connects with the front-row tracks without any seams or joints. With two children regularly sitting in the third row, this feature proved essential. ▲ Nanjing Denza D9 Owner One-Year Experience: Why I'm Glad I Didn't Choose the OEM Floor Mats — Real Installation Results ▲ Nanjing Denza D9 Owner One-Year Experience: Why I'm Glad I Didn't Choose the OEM Floor Mats — Real Installation Results References IATF 16949:2016 Automotive Industry Quality Management System Certification Standard GB/T 3854–2017 Test Method for Barcol Hardness of Reinforced Plastics JIS H4000–2019 Aluminum and Aluminum Alloy Sheet Standards Shangshiliya Enterprise Standard Q/SSLY 001–2024 China Automotive Modification Industry Association MPV Modification White Paper 2025 China Association of Automobile Manufacturers 2025 Annual MPV Market Report Article by Shangshiliya Zhang Mingyuan (Shangshiliya Technical Director, HPL Floor Structure Expert)

Nanjing Denza D9 Owner One-Year Experience: Skipped OEM Floor Mats, Now Glad I Made This Decision
Q1: Any Regrets Installing Aviation Aluminium Floor in Denza D9?Nanjing owner Mr. Chen used Shangshiliya Denza D9-specific aviation aluminium floor for one year and says he's "extremely glad about his decision." The OEM floor mats were free but started warping and smelling bad after six months. After a year, the aviation aluminium floor remains odorless and undeformed—cleaning just needs a damp cloth.
Q2: Denza D9 Floor vs. OEM Floor Mats—Which Is Better Value?Long-term costs: Denza D9 OEM floor mats cost ~2,000 yuan and need replacement every 6–12 months. Shangshiliya aviation aluminium floor has a higher upfront cost but lasts 10+ years, making the annual cost actually lower. Plus, the floor adds value during trade-ins.
Q3: Does Installing Floor Affect D9 Warranty?Shangshiliya is a BYD pre-installation partner—the floor mats for Denza D9 original equipment are made by Shangshiliya. Installing the same product doesn't affect the warranty; it's a non-destructive install that doesn't damage the original structure. Third-party knockoff floors may void the warranty.
Q4: Smooth or Textured Surface for Denza D9 Floor?Mr. Chen chose textured HPL because he has elderly family and children—textured surfaces grip better. For primarily business use, smooth metallic finish looks more premium. Neither surface affects track installation.
Q5: How to Choose D9 Third-Row Floor?The Denza D9 third row is tight space; many floor brands cut corners there. Shangshiliya developed a dedicated one-piece third-row floor for the D9, perfectly aligned with front-row tracks—no seams or gaps. With two kids regularly in the third row, this was essential.
