KUST Windshield Sun Shade for KIA K5 (Optima) 2016-2020 — Custom Fit, Dual-Layer Reflective 250T Fabric

KUST's custom-fit windshield sun shade is a foldable visor made for 2016–2020 KIA K5 (Optima) that blocks UV rays and limits heat buildup while fitting the windshield precisely.

If you own a 2016–2020 KIA K5 (Optima) and want to reduce interior heat, protect dash and upholstery from sun damage, and speed up cabin cooling, this tailored sun shade is built to match your windshield. The shade uses a dual-layer 250T reflective fabric with a silver outside and black inside to reflect sunlight and add insulation. It installs in seconds with no suction cups, folds compactly with a memory steel frame, and is not compatible with the 2021 KIA K5.

How does this shade reduce cabin temperature and AC workload?

The reflective silver layer redirects sunlight away from the windshield, while the inner black insulation layer reduces radiant heat transfer into the cabin. That lowers the starting temperature inside the car so the air conditioning has less work to do and cools the vehicle faster.

• Reflective 250T fabric rejects sunlight and glare.
• Double-layer construction improves heat resistance.
• Reduces time and energy needed for AC to cool cabin.
• Blocks up to 99% of damaging UV rays from reaching the interior.

Will this fit my KIA K5 / Optima model and how exact is the coverage?

This shade is designed specifically for KIA K5 / Optima years 2016, 2017, 2018, 2019 and 2020. The contour and size match those windshields so the cover sits flush with minimal gaps, unlike universal shades which often leave exposed sections.

• Custom cut for 2016–2020 KIA K5 / Optima windshields.
• Full coverage design prevents sun from entering at edges.
• Not compatible with 2021 KIA K5 models—check vehicle year before purchase.
• Precise fit helps protect dash, steering wheel and seats.

How easy is it to install, remove and store the shade?

Installation requires no tools, adhesives, or suction cups — simply unfold and position the shade against the windshield with the silver side facing outward. The elastic memory steel wire allows the shade to pop into shape and fold back into a compact circle for storage in seconds.

• Tool-free install and removal in seconds.
• Memory steel frame maintains shape and prevents deformation.
• Compact folding for glovebox or trunk storage.
• Durable construction stands up to repeated use and folding.

What interior protection does the KUST shade provide beyond cooling?

By blocking direct sunlight and most UV radiation, the shade helps slow fading and cracking of the dashboard, leather, and fabrics. It also reduces glare on instruments and steering surfaces, making early-morning or late-afternoon parking less damaging to interior finishes.

• Blocks up to 99% of damaging UV rays to protect surfaces.
• Limits fading and heat-induced deterioration of materials.
• Reduces glare that can accelerate wear on instrument panels.
• Provides privacy when parked and can help when resting in the car.

Who is this for: The KUST Windshield Sun Shade is ideal for KIA K5 / Optima owners (model years 2016–2020) who want a precise, easy-to-use sun shield to keep their car cooler, protect interiors from UV damage, and speed up air conditioning performance. It’s a practical purchase for daily commuters, weekend drivers, rideshare operators, and anyone who parks in direct sun regularly. Confirm your vehicle year before ordering, as this product does not fit 2021 KIA K5 models.
