AION DOT 4 SUPER BLUE is a high-performance brake fluid with an exceptionally high boiling point of 280°C. Its unique formula ensures minimal drop in boiling point, thanks to superior water-binding properties, resulting in a long-lasting fluid that may not require replacement for up to 3 years under typical highway driving conditions. With both high dry and wet boiling points, it is an ideal choice for street-driven vehicles, where brake fluid changes are less frequent than in race cars.
