Show original supplier description
The Koshi Group ARGL-19 is a carbon fiber rear spoiler crafted to enhance the aesthetic of the Alfa Romeo Giulia QV. It utilizes Prepreg Carbon Fiber from Delta-Preg, a supplier renowned for its use by high-performance automotive manufacturers like Ferrari and Lamborghini. The manufacturing process involves Autoclave technology, curing at 140°C under 6 bar of pressure, ensuring exceptional material integrity. This spoiler features a high-gloss clear coating, specifically PPG-D880, complemented by a PPG-D8122 ceramic clear coat for a lasting, durable finish. Its construction boasts a thickness of 0.6mm, providing significant resistance while maintaining a lightweight profile. Quality control measures are in place to guarantee a precise fit as a direct replacement for the original equipment manufacturer (OEM) part. Beyond its robust construction, the ARGL-19 spoiler is designed to add an exotic and stylish visual appeal to the Alfa Romeo Giulia QV. The installation process is rated as very easy, making it an accessible upgrade for owners looking to customize their vehicle. The product dimensions are 127 x 24 x 4 cm and it weighs 0.220 kg.
