Full Power Air Box – Derbi / Gilera SMT / Aprilia SX

Crafted in our own workshop, this Full Power air box is designed for the Derbi, the Gilera SMT and the Aprilia SX. It works on all Derbi Senda models. The idea? Replace the stock air box, designed to cut noise and limit performance, with a much larger unit that uses the oil tank space (once removed) to deliver nearly 200% more air volume and a real fresh air reserve.

The filtration method has also been reworked to improve filling. It fits with our PWK large carburettor sleeve, or with the original Derbi sleeve for small 12 to 21 mm Dell'Orto carburettors.

The pack includes:

• The Full Power air box
• The air filter
• Fitting instructions

Benefits:

• 📈 Noticeable power gain over the stock air box
• ⛽ Lower fuel consumption
• 🎯 Sharper throttle response and pick-up
• 📊 More performance from low and mid range
• 🏁 Result measured on a power dyno
• 🔊 Less noise while gaining in efficiency

Note: compatible with high-mount exhausts on the ignition side. The PWK carburettor sleeve is sold separately or as an option.
