Pigenius Windshield Sun Shade for BMW i4 (G26) & 4 Series Gran Coupe — BLAZBLOCK Reflective Aluminum, Sensor-Friendly Fit

Pigenius BLAZBLOCK windshield sun shade is a precision-fit, reflective aluminum sun protector made to block heat and preserve the interior of BMW i4 (G26) 2022–2026 and BMW 4 Series Gran Coupe 2024–2026 models.

Built specifically for the G26 body style and its variants (eDrive35, eDrive40, M50, M60, 430i, M440i), this sun shade uses a reflective aluminum film and a rigid accordion design to reduce radiant heat on the dash, seats and electronics while staying securely in place. It combines a tear-resistant one-piece construction with sensor-friendly cutouts and soft flocked edges so it protects both cabin surfaces and delicate windshield pillars without obstructing cameras or sensors.

How does this sun shade fit the BMW i4 and 4 Series Gran Coupe accurately?

The Pigenius BLAZBLOCK is laser-measured to match the G26 windshield profile and curvature, including allowances for mirror mounts and A-pillar geometry. Its compact accordion fold and elastic storage bag make it easy to install, fold and store without strain.

• Model-specific sizing for BMW i4 (G26) 2022–2026 and 4 Series Gran Coupe 2024–2026
• Precision cutouts for camera and sensor areas to avoid interference
• Fits M50, M60, 430i and M440i variants
• Accordion fold collapses to approximately 3 in. thick by 9 in. wide for neat storage

What materials and construction keep it durable and reflective?

This sun shade uses a reflective aluminum film bonded in a diamond-grid, heat-pressed single-piece structure that resists tears and delamination. Thick, stiff panels preserve shape so the shade won’t sag or droop during hot weather, extending usable life over softer, flimsy competitors.

• Reflective aluminum film for efficient radiant heat reflection
• Diamond grid, heat-pressed one-piece construction for tear resistance
• Rigid panels to prevent sagging at high temperatures
• Soft flocked edges to protect interior trim and windshield pillars

Will it interfere with windshield cameras, sensors or interior trim?

No—Pigenius designed this shade with precise cutouts and sensor compatibility so factory cameras and sensor arrays aren’t blocked or exposed to unnecessary heat. The soft flocked perimeter cushions contact points to prevent scratches on the A-pillar and dashboard surfaces.

• Sensor-friendly cutouts keep cameras and driver-assist sensors unobstructed
• Flocked edge protection prevents abrasion on trim and pillars
• Secures with sun visors—no suction cups needed—so windshield adhesives aren’t stressed
• Maintains shape for reliable coverage over repeated use

How easy is it to use and store every day?

The accordion fold format is engineered for quick deployment and compact storage. It slips into the included storage bag and maintains low bulk thanks to its self-weight and fold pattern, making daily use practical for commuters and owners who park outdoors.

• Accordion fold design opens and closes in seconds
• Self-weighted panels fold neatly into the storage bag
• Ultra-compact folded dimensions for glovebox or trunk storage
• No tools or suction cups required—keeps installation simple

Who is this for: The Pigenius BLAZBLOCK windshield sun shade is for BMW owners who want a model-specific, long-lasting sun blocker that protects dashboards, upholstery and in-car electronics without obstructing cameras or sensors. It’s ideal for i4 and 4 Series Gran Coupe drivers who park in direct sun frequently, value neat daily storage, and prefer a durable shade that stays rigid in extreme heat.
