PIRANI INS-BOX SET EFRA-INS202301

NEW PRC INS-BOX SET for 1/8 and 1/10 on road scale.

EFRA APPROVED with number of homologation INS202301 Super light weight (-20%), 8mm lower and 3mm diameter less than other ins-boxes.

The INS-BOX is made of light weight ABS, color black.

The sponge is low profile to reduce the total height of the ins-box.

The air inlet is made by x2 8mm holes and then air pass through the "turbo effect" and goes into the carburetor with more speed and more pressure.

This increase of air pressure makes the top speed rising of 2km/h, more constant carburetion and more torque.

All combined with new aero design, especially designed for new 1/8 on road bodies.
