Fredy · July 30, 2026

Great sound and airflow

Aiden · April 7, 2026

Bought my car with a Dflow. It was dirty so i decided to buy a new one. Didnt know the difference but im glad i picked SynoilD! Started getting turbo noises i never heard before and I can feel the difference! Try not to push it too hard in one place while installing or itll start crumpling. Super easy too install just a hose clamp.
