KUST Windscreen Sun Shade for KIA K5 / Kia Optima 2016-2020 — Custom-Fit, Double-Layer Reflective UV Blocker

The KUST Windshield Sun Shade is a precision-made, foldable windshield cover designed specifically for 2016–2020 KIA K5 / Kia Optima to block UV rays and reduce cabin heat.

This custom-fit sun shade is shaped to the exact windshield dimensions of 2016–2020 Kia Optima (KIA K5) models, excluding the 2021 redesign, and uses a double-layer reflective fabric to keep your interior cooler. Built with a silver reflective outer layer and a black insulating inner layer, the shade minimizes heat buildup, protects dash and upholstery from sun damage, and folds away quickly when not in use. It installs without suction cups or adhesives, relying on an elastic memory steel wire to hold shape and simplify storage.

How does this shade reduce interior temperature?

The shade reflects sunlight before it penetrates the glass, lowering the amount of solar energy that enters the cabin. With a high-density 250T reflective fabric and a double-layer construction, it helps the air conditioner reach a comfortable temperature faster and reduces the time you need to run the AC.

• 250T reflective fabric with high density for strong light reflection
• Double-layer design: silver outer layer and black insulating inner layer
• Blocks up to 99% of harmful UV rays to minimize heat transfer
• Speeds AC cooling, saving fuel and energy when starting from a hot car

Will this shade fit my KIA K5 / Kia Optima?

This sun shade is tailored specifically for the 2016–2017–2018–2019–2020 KIA K5 / Kia Optima windshields and is not compatible with the 2021 KIA K5 model. The custom cut ensures a full coverage fit with no gaps along the glass for better sun blocking and an improved appearance compared with universal sizes.

• Designed for 2016–2020 Kia Optima (KIA K5) windshield dimensions
• Full-coverage profile eliminates gaps that let sunlight through
• Not compatible with 2021 KIA K5 windshield shape
• Precision edges align with factory glass curvature for a neat look

How easy is it to install, fold, and store?

Installation is fast and tool-free: unfold the shade, position it inside the windshield with the silver side facing out, and the black side inward. The shade uses an elastic memory steel wire that keeps its shape, making folding intuitive and packing compact for the glovebox or trunk.

• No suction cups, adhesive, or hardware required for installation
• Elastic memory steel wire prevents permanent deformation
• Folds in seconds into a compact disc for convenient storage
• Lightweight construction makes handling one-person friendly

What interior protection does the shade provide?

By reflecting sun and blocking UV, the shade helps slow fading and cracking of dashboard materials and upholstery. While not a replacement for climate control, it reduces direct sun exposure and offers a cooler, more comfortable cabin when you return to the vehicle.

• Blocks up to 99% of damaging UV rays that cause fading
• Reduces heat stress on dashboard, leather, and plastics
• Creates a shaded space for quick in-car breaks or naps
• Durable fabric resists wear from repeated folding and use

Who is this for? The KUST Windshield Sun Shade is ideal for Kia Optima owners (model years 2016–2020) who want a neat, vehicle-specific sun shield that delivers maximum windshield coverage and easy handling. It suits drivers seeking faster interior cooldown, protection for dash and upholstery, and a low-hassle storage solution. Avoid if you drive a 2021 KIA K5 or need a universal-size shade—this product prioritizes fit and finish for the specified Optima years.
