Stainless Steel vs Plastic Snorkels: Which Should You Fit to Your 4WD?

If you're shopping for a snorkel, the first fork in the road is material: a mass-produced plastic (polyethylene) snorkel or a fabricated stainless steel one. Both raise your air intake. The differences show up in durability, airflow, fitment and looks. Here's an honest comparison from a workshop that builds stainless snorkels every day in Melbourne.

Durability

Plastic snorkels are UV-stabilised and generally hold up, but they can fade, go chalky and become brittle after years in the Australian sun. Branch strikes on tight tracks can crack them.

304 stainless steel doesn't fade, warp or go brittle. It takes a branch strike and keeps its shape, and a brushed finish can be polished back if it picks up scratches. That's why we back every Canna Fabrication stainless snorkel with a lifetime warranty.

Airflow

Most factory intakes and many plastic snorkels are moulded with bends, ribs and step-downs that add restriction. A fabricated stainless snorkel is mandrel-formed tube with a smooth internal bore — our standard sizes run 4", 4.5" and 5" depending on the engine. A larger, smoother intake tract reduces restriction; many customers notice better throttle response and induction sound, particularly on tuned or turbocharged diesels.

Water crossings

Material matters less here than sealing. Plenty of factory-style snorkels aren't sealed systems from head to airbox. A stainless snorkel paired with a sealed stainless airbox (or a proper stock-airbox adapter) gives you a sealed path for deep crossings.

Price

Plastic wins on price — typically $300–$700 fitted. A hand-built stainless snorkel starts around $800–$1,200 because it's cut, welded and finished by hand for your exact vehicle, not pulled from a mould. Whether that's worth it depends on how long you keep your 4WD and how hard you use it.

Looks

Subjective, but it's the reason many people go stainless: brushed silver or powdercoated black steel on the A-pillar looks like a piece of fabrication, not an accessory. Finish options are covered in our snorkel options guide.

The verdict

If you want the cheapest way to raise your intake, plastic does the job. If you want an intake that flows better, lasts the life of the vehicle and looks the part, stainless is the better long-term buy. We build stainless snorkels for Toyota, Ford, Nissan, Volkswagen, Mazda, Isuzu and Holden 4WDs — every one made to order in Melbourne from 304 stainless.
