What Does the Ténéré 700 Snorkel Filter Actually Do?

Short answer: the snorkel is the Ténéré 700's intake mouth, the very first opening dusty air passes through. A snorkel filter is an oiled foam element fitted at that opening, so heavy dust gets stopped at the front door instead of being dealt with deep in the airbox. On the T700, that's the FunnelWeb FWF 7889 snorkel filter ($59.95).

Why the intake mouth matters

Every gram of dust your engine doesn't eat was stopped somewhere along the intake path. Most riders think only about the main filter, but filtration works best in stages, and the earliest stage is the cheapest place to win. Coarse, heavy dust (roost from the rider ahead, sand kicked up in a wash) is easy to catch at the snorkel while it's still moving slowly and hasn't been drawn into the airbox currents.

Stop the heavy stuff at the mouth, and the downstream filters spend their capacity only on the fine dust that matters most.

What changes when you fit one

• The main filter stays cleaner, much longer. On group rides in dust, the snorkel filter takes the visible beating; teardown day shows how much never got further.
• Mid-trip service gets easier. The snorkel element is the most accessible filter on the bike, a quick swap at camp versus opening the airbox.
• It's oiled foam, like the rest of the system. Washable, reusable, and it uses the same pyramid-profile foam principle: more surface area, more dust held before flow drops.

Snorkel filter vs. pre-filter, aren't they the same thing?

No, they're sequential stages. The snorkel filter (7889) sits at the intake opening and catches the heavy dust first. The pre-filter (7890) sits inside the airbox ahead of the main element, absorbing the sustained fine-dust load. The main filter (7891) is the final guard. Desert and multi-day riders run all three; the system is designed to layer.

Frequently asked questions

Does a snorkel filter choke the intake?

A clean, properly oiled foam element at the snorkel flows freely, the T700's intake isn't running at the ragged edge of airflow in normal riding. What actually costs power is a neglected main filter; the snorkel stage exists to prevent exactly that.

Do I need the snorkel filter if I already run the pre-filter?

For occasional dust, main + pre-filter covers most riders. Add the snorkel stage when your riding involves sustained dust, desert, racing, long group rides, or when you want maximum time between airbox openings on a big trip.

How do I service it?

Same as any FunnelWeb element: wash, dry fully, re-oil, reinstall. Never use No-Toil brand products on FunnelWeb foam, their chemistry breaks down the foam adhesive.
