Sakura A-31790 Air Filter for Skoda Fabia & VW Polo Diesel | Premium Soft PU Frame Intake | Replaces 6Q0129620D & 6Q0129620E

Protect the high-torque performance of your diesel engine with the Sakura A-31790 Air Filter, precision-designed for the Skoda Fabia and Volkswagen Polo (9N/6R) diesel variants. Turbocharged diesel engines require a massive volume of clean air to ensure complete combustion and prevent premature turbocharger wear.¹ This filter acts as a high-density shield, trapping microscopic road grit, soot, and silica before they can reach your engine’s internal components.

The A-31790 features a specialized Soft PU (Polyurethane) Frame.² In the compact engine bays of European hatchbacks, heat and vibration are constant. The Soft PU frame acts as a high-compression gasket that perfectly contours to the airbox housing. This creates a vacuum-tight seal, eliminating “dirty air bypass” and protecting the sensitive Mass Air Flow (MAF) sensor, which is critical for maintaining fuel economy and smooth power delivery.
