TNT fiberglass shutters derbi euro 1, 2 & 3

Here are the new valves TNT MOTOR for engine DERBI. Certainly very cheap but still very good quality and finish. These valves are really the best in price / quality ratio. The aluminum base is appreciated for the strength, the non-deformability and the change of the slats with ease! The slats are fiberglass and the thickness is better studied than the original to achieve a good power regime, you will certainly notice that they are joined to the example of many valves like competition BIDALOT, ATHENA .. .

Lamella stops fixed by 2 Phillips screws are specially designed / drilled to avoid gas clusters. These valves will offer you a little more performance than the origins. We will simply regret the lack of a venturi (diffuser) but it is not in any case disturbing if you use a big pipe exit. Allow seal valves against housing, we sell only in separate.
