Clearly cool parts from Bullet Air
New from French parts and accessory designers Philippe and Thomas Blot, a Harley enthusiast father and son team, these new designs of high-speed air filters and clear velocity stacks are available in a selection of dimensions (or custom applications) to fit most popular carbs, including CVs, S&S, Mikuni and other aftermarket brands.
The application-specific polished 6061 aerospace grade T6 heat-treated precision CNC machined aluminum cone attaches to the carb (or intake) with a one-piece adapter ring.
The durable clear 'dome' is manufactured from shock and heat resistant borosilicate - a material that is similar to, but sometimes regarded as superior in thermal shock resistance properties, to lime-soda based US specification Pyrex branded glass.
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents and is known for having a very a low coefficient of thermal expansion - which means it will also be a lot more resistant to discoloration as the surface of the glass will remain less prone to particulate impregnation for longer.
Manufactured in France, like any retro-fit accessory, some re-mapping may be necessary when being used on fuel-injected engines, but they do work and "work well with fuel injection" as well as normally aspirated engines, according to Thomas Blot.
