A GWM Cannon snorkel fits all diesel 4WD variants — Cannon, Cannon X, Cannon Alpha and XSR — from 2020 through 2025+, connecting to the OEM airbox with no replacement needed. Three entry styles exist (mid-entry, short-entry, forward-facing ram) in either UV-stabilised polymer (lighter, cheaper) or 304/316 stainless steel (tougher, heavier).
It raises the air intake to roofline height for deeper water crossings — the Cannon's stock wading depth is around 500mm — but it's an intake relocation device, not a performance mod, and it won't fix Cannon turbo lag.
Which Snorkel Fits the GWM Cannon?
The first worry most owners have when searching for a Cannon snorkel is whether the listing actually covers their specific variant. Fitment is confirmed across the standard GWM Cannon, Cannon X, Cannon Alpha and XSR, from the 2020 model year through to current 2025+ stock.
The Cannon X sits on a slightly different suspension tune and carries different lower-guard trim, but the A-pillar and airbox interface are shared, so snorkel fitment carries across. If you're running a tray-body conversion or a heavily modified front end, verify the guard profile is still factory before ordering — the guard is where the snorkel penetrates.
See our GWM Cannon bull bar fitment & recovery guide for how front-end accessories interact with guard-mounted components.
Snorkel Styles: Which Suits You?
Three entry styles are available for the GWM Cannon, and each suits a different primary use.
| Style | Intake position | Best for | Trade-off |
|---|---|---|---|
| Mid-entry | Roughly roofline height | Maximum water-crossing depth | Most common, balanced choice |
| Short-entry | At or just above bonnet line | Cleaner look, dustier trails | Reduced water-crossing depth |
| Forward-facing ram | Roofline, inlet facing forward | Slight ram-air effect at highway speed | Less spray protection in wet crossings |
Mid-entry positions the intake head roughly level with the roofline — the most common configuration and the best all-rounder for water crossings. Short-entry brings the head lower, at or just above the bonnet line, for a cleaner look, but trades away wading depth.
Forward-facing ram units orient the inlet toward travel and claim a slight positive-pressure effect at highway speed — but offer less protection against spray from oncoming water in a Top End wet-season crossing.
Stainless Steel vs Polymer: An Honest Comparison
Most listings mention material in one line and move on. Nobody explains what that choice actually means after two hard seasons in Australian conditions — so here's the honest version.
Polymer (ABS / HDPE)
- Lighter and cheaper (kits often under $300 landed)
- Fine for mild climates & occasional use
- Needs UV-stabilised grade or it goes brittle
- May be fragile by a third Darwin dry season
Stainless steel (304 / 316)
- Far tougher, handles branch strikes & corrugations
- 316-grade is the most corrosion-resistant
- Australian hand-welded units cost more
- Adds meaningful weight at the A-pillar
Polymer snorkels — typically ABS or high-density polyethylene — are lighter, cheaper and adequate in mild climates, but UV exposure is the enemy: a non-stabilised polymer that looks solid after one dry season may be fragile by season three. Stainless steel, particularly 304-grade (with 316 the more corrosion-resistant option), shrugs off branch strikes and corrugations. The honest downside is weight at the A-pillar.
For a school-run ute that sees the occasional weekend track, a quality UV-stabilised polymer kit is a sensible starting point. For serious remote touring or Top End wet-season work, stainless earns its premium.
What's in the Snorkel Kit?
A complete GWM Cannon snorkel kit should arrive ready to fit without a separate hardware order. Standard inclusions across the main market options are:
- Snorkel body — 76–100mm internal diameter (3–4 inch).
- Inlet head assembly — the visible intake at the top.
- A-pillar mounting bracket and guard bracket + hardware.
- Nylock anti-vibration nuts and bolts.
- Fitment/cutting template — a guide only; verify against your actual guard.
- Guard-penetration gasket/seal — confirm per listing; source weatherproof sealant if omitted.
OEM airbox compatibility is confirmed on kits listed for the 2020–2025+ Cannon diesel — no replacement airbox is required, the snorkel connects to the factory box. If a listing omits the gasket set, factor in sourcing sealant, because the seal is what makes the whole thing work.
Can I Install It Myself?
A mechanically competent owner can fit a Cannon snorkel without professional help — but you need to be clear-eyed about what the job involves, because it's not reversible.
- Trial fit & template. Offer up the snorkel body and use the supplied template to mark the guard and A-pillar positions. Do a full trial fit before any cutting — panel variations between production runs mean the template is a guide, not gospel.
- Mark and cut the guard. Mark the guard penetration accurately, then cut cleanly with a hole saw (typically 60–80mm). This is the permanent, high-stakes step — measure twice, cut once. Deburr and treat the cut edge against rust.
- Mount the body & brackets. Fit the A-pillar mounting bracket and guard bracket, then secure the snorkel body with the supplied Nylock anti-vibration hardware. Don't fully tighten until alignment is confirmed.
- Seal every penetration. Fit the guard-penetration gasket and A-pillar seals. This is what stops water tracking into the A-pillar or airbox — the whole point of the snorkel. A failed seal makes the snorkel worse than useless.
- Reconnect the airbox. Connect the snorkel to the OEM airbox (no replacement airbox needed on 2020–2025+ diesel kits). Check the join is airtight with no kinks, then torque all fasteners and re-check after your first drive.
Guard cutting is permanent: the install requires cutting through a visible, painted front guard on a vehicle you rely on. Measure and template twice before cutting — a misaligned hole-saw pass can't be undone. At least one major supplier recommends professional fitment for exactly this reason. If in doubt, pay for the cut.
Does a Snorkel Affect Engine Performance?
Owners consistently mention turbo lag from a standing start as the Cannon's most-noticed characteristic — so it's worth being honest about what a snorkel does and doesn't do here.
A snorkel is an air-intake relocation device, not a performance component. Its job is to raise the inlet point for water crossings and cleaner air on dusty trails. The body on Cannon kits runs 76–100mm internal diameter, consistent with or slightly larger than the factory intake, so a correctly fitted snorkel doesn't restrict airflow. Forward-facing ram units generate a slight positive pressure above about 80km/h — noticeable on paper, not in the seat.
A snorkel will not fix Cannon turbo lag. What a poorly fitted or undersized one can do is introduce restriction — a kinked airbox connection or an undersized body — which makes throttle response worse. Fit a correctly sized kit properly, and intake performance stays stock; that's the goal.
Whatever you fit, wade responsibly and stick to formed crossings — follow Tread Lightly! principles to protect track access. You can confirm your Cannon's stock specs on GWM Australia's site before planning a build.

GWM Cannon Snorkel FAQs
Does the snorkel fit the 2025 GWM Cannon?
Yes. Snorkel kits listed for the GWM Cannon cover the 2020 through 2025+ diesel 4x4 range, including Cannon, Cannon X, Cannon Alpha and XSR variants. Always cross-check the kit's stated fitment against your Cannon's build-year compliance plate, and confirm the front guard is still the factory panel (not a replaced or modified one).
Will fitting a snorkel void my GWM warranty?
Not automatically. Under Australian Consumer Law, fitting an aftermarket accessory doesn't void your whole warranty — GWM would need to show the snorkel directly caused the specific fault being claimed. The real risk is a poor install: if a bad guard seal lets water into the airbox and damages the engine, that damage is on you, which is why sealing quality matters so much.
Is a snorkel road-legal in Australia?
Yes, when fitted correctly. Snorkels are legal across Australia provided the intake doesn't dangerously obstruct vision and the fitment follows the manufacturer's instructions. Choose a kit designed for the Cannon and marketed for Australian road use, and you're compliant.
Does the snorkel fit the Cannon XSR body?
Yes. Kits confirmed for the XSR account for its body trim. Note the XSR already has a higher stock wading depth (around 700mm versus 500mm on standard Cannon variants) thanks to its off-road focus, so a snorkel extends an already more capable platform for serious water crossings.
Do I need to buy a new airbox with the snorkel?
No. On kits listed for the 2020–2025+ GWM Cannon diesel, the snorkel connects to the OEM airbox — no replacement airbox is required. The snorkel simply relocates the air intake point from the engine bay up to the A-pillar; the factory airbox and filter stay in place.
How much deeper can I wade with a snorkel fitted?
A snorkel raises the air intake to roughly roofline height, so the limiting factor shifts from the engine intake to other water-sensitive points (electricals, diff breathers, door seals). The Cannon's stock wading depth is around 500mm; a snorkel lets you cross deeper water safely, but you should also extend diff and gearbox breathers and cross slowly to create a bow wave. A snorkel alone isn't a licence to wade recklessly.
