In short
- What it is: the 2G Engineering Hammer Intake enlarged airbox lid for Ducati Desert X, Desert X Rally and Desert X Discovery with the 937 cc Testastretta 11° engine (2022–2025). Air filter not included: use it with the filter you already have.
- What it fixes: jerking and snatchy throttle at low rpm.
- Dyno-tested result: about +4 hp and +6 Nm between 3,000 and 5,500 rpm, with the stock ECU and no remap.
- Plug & Play and reversible: it fits the stock airbox with no cutting or drilling.
Low-rpm snatchiness and torque dip on the Desert X: where they come from
Off-road in slow, technical sections, and on the road in traffic, the stock Desert X tends to have a snatchy throttle response at low rpm, just when you need it to be smoothest. The dyno also shows a torque dip between about 4,300 and 5,200 rpm.
The main cause isn't the air filter but the way air gets into the airbox: the stock lid has a very small air inlet, designed mainly to meet European noise homologation limits.
Why a performance air filter alone isn't enough
Many Ducati owners start by fitting a performance air filter for the Desert X. The problem is that the filter sits behind the same stock air inlet: if air can't get into the airbox, a freer-flowing filter changes very little. It's like having a marathon runner's lungs and breathing through a straw.
More air, protected filter
On a bike that also goes off-road, more air shouldn't mean more dust in the engine. Our lid enlarges the air inlet with a geometry designed to keep the filter shielded from water and dust, with the reliability of the stock system.
The solution: 2G Engineering Hammer Intake
The lid replaces the restrictive factory one and enlarges the air inlet. It works with the filter you already have: any filter with the original dimensions will fit, both the stock filter and performance filters. Every lid is designed and made in Soliera (Modena), in the heart of Italy's Motor Valley, from carbon-fiber-reinforced PPA.
What changes on the road
- Smooth low-rpm response: throttle response becomes progressive and predictable, with no jerks.
- More torque and power without a remap: about +4 hp and +6 Nm between 3,000 and 5,500 rpm measured on the dyno with the stock ECU. Peak power changes only slightly. No remap needed.
- Intake sound: deeper and fuller, especially from the mid-range up.
- Keep the filter you already have: it works with the stock filter and with any OEM-size performance filter.
The chart compares a stock Desert X with the same bike fitted with the 2G intake system, without a remap: torque is higher from low rpm and the dip between about 4,300 and 5,200 rpm disappears, while peak power changes only slightly.

Frequently asked questions
Is the air filter included?
No. This version contains only the enlarged airbox lid: you use it with the filter you already have. If you also need a filter, choose the kit with the 2G performance air filter.
Which filters can I use?
Any filter with the original dimensions: the stock filter and OEM-size performance filters.
Do I need to remap the ECU?
No. The lid is designed to work with the stock Desert X ECU: the quoted gains (about +4 hp and +6 Nm between 3,000 and 5,500 rpm) were measured without a remap.
Exhaust or intake: which should I upgrade first?
They do different jobs: the intake controls how much air gets into the engine, the exhaust how the gases get out. Our kit is designed to deliver results with the stock exhaust and costs a fraction of a full exhaust system.
Is the filter still protected from water and dust off-road?
Yes. The lid enlarges the air inlet with a geometry designed to keep the filter shielded from water and dust, just like the stock system.
Which versions does it fit?
It fits the Ducati Desert X, Desert X Rally and Desert X Discovery with the 937 cc Testastretta 11° engine (2022–2025).
Can I return the bike to stock?
Yes. No cutting or drilling is needed: just refit the stock lid.
How long does it take to fit?
About one hour, with no modifications to the bike.
How long does shipping take?
All kits are in stock and ship within 24 hours, worldwide. You have 15 days from delivery to return the product if you're not satisfied.
