As far as I didn’t find any carbon fiber airboxes available for my VHPD on Ebay or elsewhere I decided to order a new one here in Russia.
Order placed and my original (strange quality) glass-fiber airbox is given to a workshop as a measurement example.
Preliminary cost is about 500 eur (incl making a matrix and a product itself).
Will post pictures when the airbox is ready.
As for now - fingers crossed for luck.
