Bonnet insulation kit and firewall blanket for square-nose classic Mini Clubman models.
From the manufacturer:
Original bonnet felts were made of a material that is no longer available, so we have taken the opportunity to develop our own more efficient item. When fitted you will notice an enormous difference in the lack of noise from the engine and exhaust noise. Made out of a tough PVC coated felt material, we then "quilt" it on our sewing machines to look really elegant. The bulkhead piece is made of the same material and can be fitted between the bulkhead and engine.
Special order, lead time required.
