Blow off valve trumpet with filter mount.

If your BOV vents to the atmosphere for sound and you drive in dirty environments, the 5703 trumpet is for you. It’s designed to enhance the blow-off sound like a regular trumpet but includes a 38mm (1.5”) section that allows you to mount a suitable filter such as our 5711 (sold separately).

This ensures your BOV is protected from dust, sand, mud and other debris, whilst giving a much louder and more unique sound than using a regular hose barb outlet.

Suitable for use on SXV, Mach 2, Hybrid, Respons, and Deceptor Pro II BOVs.
