How the triple layer foam protects your engine

The graded polyurethane foam uses a coarse outer layer to stop larger debris, a medium core to capture fine dust and a fine inner layer to trap the smallest particles. This progressive filtration keeps restriction low while maintaining excellent engine protection in real-world UK driving conditions.

Fitment
