Why Stilo Intercoms?

Stilo intercoms were born from frustration. Ludovico Fassitelli — an ex-Italian Rally Champion — was fed up with the poor communications available in rally cars and dedicated himself to building the best electronics and noise cancellation in the business. The result transformed rally communications worldwide, and the WRC has been testimony to this ever since: the vast majority of professional rally crews run Stilo helmets and intercoms.

As cars became louder — with high-revving Super 1600 and Super 2000 transmissions — Stilo developed Active Digital Noise Cancellation: the only range in the world offering this technology. No other manufacturer has been able to replicate it.

Important: Stilo intercoms can be used with other helmet brands via conversion cables, but all Stilo intercoms are optimised for Stilo helmet electronics. The full benefit of active digital noise cancellation is only realised when used with a Stilo helmet or a helmet fitted with Stilo electronics.

Analogue vs Digital — Which Do You Need?

Type Best For Noise Cancellation Models
Analogue Group N, less noisy cars, club level Good — passive filter Trophy 2, WRC 03, WRC 9V
Active Digital All levels — especially noisy cars Best available — active digital DG-20, DG-20 Raid, DG WL-10
Wireless Digital Crews wanting no helmet cables Best available — active digital DG WL-10 + WL Keys

The digital difference: With analogue electronics, there is only so far noise can be filtered before crew communication is also reduced. Digital separates the direct voice signal from surrounding noise, converts both to digital, applies the chosen noise cancellation level, and outputs clean audio — all in a millisecond. The result is a dramatic improvement in communication clarity in even the noisiest rally cars.

Current Stilo Intercom Models

Stilo Trophy 2 — Analogue, Club Level

Designed for Group N and less noisy cars. The Trophy 2 uses electronic microphone electronics with limited noise cancelling — ideal for club-level competitors in quieter cars. Note: Trophy electronics are required in your helmet. This intercom will ONLY work with the Stilo Trophy Rally helmet.

  • Trophy electronics for less noisy cars
  • Individual driver and co-driver volume controls
  • Runs off 9V battery or 12V car supply (adapter YB0100 required for 12V)
  • Special design case with roll bar fitting
  • High quality metal jacks
  • ON/OFF LED light and camera connection at rear

Stilo WRC 03 — Analogue, Most Popular Mid-Range

The original Stilo WRC intercom — and still the most popular in the range for its price point and performance. Excellent analogue noise cancelling using WRC electronics. Compatible with Stilo Trophy Plus, all WRC helmets, and ST6 helmets fitted with standard electronics. Conversion cable AC0200 available for other helmet brands.

Stilo WRC 9V — Analogue, Enhanced Noise Filter

Born from the WRC 03, the WRC 9V adds an extra analogue noise filter switch positioned between the volume controls — developed specifically for high-revving cars like the Escort BDG. Also includes a booster switch to increase output sound levels for on-board camera systems, which previously couldn’t pick up crew communications at standard WRC frequencies.

  • WRC electronics with analogue extra noise filter
  • Individual driver and co-driver volume controls
  • Runs off 9V battery or 12V car supply
  • Built-in booster switch for noise level output
  • Switch to adjust rear connection from output to input

  • ON/OFF LED light and camera connection at rear

The Digital Revolution — Active Digital Noise Cancellation

The DG-30 was the first Stilo active digital intercom, developed when analogue noise filtering reached its limits. Today the range has evolved into the DG-20 and DG WL-10 — the most advanced rally intercoms available anywhere in the world. If you want the ultimate noise cancellation in motorsport, you need WRC helmet electronics and a Stilo active digital intercom.

Stilo DG-20 — Current Digital Flagship

The DG-20 supersedes the DG-10 with improved independent noise cancellation, smartphone app programmability, and USB-C future-proofing. As used by factory rally teams worldwide.

  • Digital Active Noise Cancellation — real-time signal processor with advanced algorithms
  • Dual independent digital filters — individually set for driver and co-driver
  • Programmable via smartphone app — Android and Apple, free to download
  • Saved configuration profiles — store multiple setups for different cars or events
  • Stage and Road modes — blocks external comms during stages; allows team radio and phone in road mode
  • Integrated Bluetooth — mobile phone connectivity in road mode
  • Camera connection — records crew communication for post-rally analysis
  • Radio interface — integrates with team radio systems
  • USB-C data port — firmware updates via laptop, future-proofed
  • 12V car supply — no battery failure risk
  • Broad compatibility — all Stilo intercom-equipped helmets and headsets (excluding Trophy); also ZeroNoise, Sparco, Peltor via Nexus connectors
  • Supplied with WRC Nexus male plugs for direct use with Stilo WRC helmets

Stilo DG-20 Raid — Off-Road & X-Country

Built for X-Country, Raid, and Dirt racing — where vibration, dust, and temperature fluctuations are constant challenges. The DG-20 Raid uses a dedicated Signal Digital Analyser (SDA) filter for real-time ambient noise monitoring, with adjustable voice returns and microphone gain for tailored audio in exposed cockpit environments.

  • Digital Active Noise Cancellation with SDA filter
  • Integrated female helmet connection cables — no additional adaptors required
  • Adjustable voice returns and microphone gain — independently controlled
  • Voice equalisation adjustment — fine-tune frequency response for helmet acoustics
  • USB-C interface for DG-20 app control (Android)
  • Compatible with all Stilo-supplied microphones (Magnetic Dynamic and Electret)
  • Camera and radio connections built in
  • Note: AC0204.2 adaptor required for use

Stilo DG WL-10 — Wireless Digital Intercom

The world’s first wireless rally intercom. Based on Stilo’s active digital noise cancellation platform, the DG WL-10 eliminates helmet cables entirely — both crew members connect wirelessly via WL Keys plugged into their helmets. Wireless range up to 10 metres, allowing crew to exit the car with helmets on and still communicate.

  • Wireless connection — no helmet cables in the cockpit
  • Active Digital Noise Cancellation for both driver and co-driver
  • 4 noise cancellation levels — adjustable per crew member
  • Individual volume controls
  • Stage and Road modes — Bluetooth phone connectivity in road mode

Frequently Asked Questions

Which Stilo intercom do I need for my rally car?
For club-level competitors in quieter cars (Group N, historic): WRC 03 or WRC 9V. For any car with significant engine or transmission noise: DG-20. For crews who want no helmet cables: DG WL-10 + WL Keys. Contact Rex Harris (RSM certified radio engineer) for a free recommendation based on your specific car and series.

Can I use a Stilo intercom with a non-Stilo helmet?
Yes — via conversion cables (AC0200 for Nexus 4-way helmets). However, the full benefit of active digital noise cancellation is only realised with Stilo WRC helmet electronics. We can also retrofit Stilo WRC electronics into many non-Stilo helmets — contact us for compatibility advice.

What replaced the Stilo DG-10?
The DG-10 has been discontinued and replaced by the improved Stilo DG-20, which adds dual independent digital filters, smartphone app programmability, USB-C firmware updates, and improved noise cancellation.

Is the DG WL-10 compatible with all Stilo helmets?
No — the DG WL-10 wireless system requires a Stilo Venti WRC helmet with the WL-10 wireless port. It is not compatible with standard Stilo helmets without this port.

What is the YA0001 emergency kit?
The YA0001 is an emergency helmet wiring kit carried by all professional rally teams in their service vehicles. If your helmet electronics fail during an event, this kit allows you to restore communications quickly without returning to service.

Do you ship Stilo intercoms to Australia?
Yes — we ship fast across New Zealand and Australia with tracked delivery and genuine stock on hand.
