Great addition to a snorkel

Great Precleaner

I purchased one of these for my Land Rover Defender. The team helped me select the right size and the product is much better than the stock one I had purchased. Works as advertised. Great product

A must have for snowy environments

Living in NY the regular snorkel heads will get clogged and frozen with snow/ice. Having the upgrade snorkel head on it ensures that I’ll never have that problem again. SUUUUPER easy install that only took about 5 minutes. I absolutely recommend this for anyone needing to keep fresh clean air getting in their engine!

Fit perfect!

I ordered the Snorkel Upgrade for my 5th gen 4Runners Dobinson Snorkel. The snorkel fit PERFECTLY! And was very easy and straight forward to install. The insulation tape I ordered with it made for a nice snug fit, and hassle free. Love my new Snorkel Upgrade!

Fantastic product that keeps my engine breathing cleaner fresher air. An added bonus is its one of the best looking snorkel heads out there. Generally if it looks right then it is right and the snorkel upgrade does look very right

How the Precleaner works on your Snorkel?

Debris are ejected out by the cyclonic-like force created inside the dome from the rotor. It's this force of spinning the debris that pushes them out the ejection slit.  No need to empty trapped dust, or turn your snorkel to the side in rain, snow or heavy dust.

Extends filter life by precleaning the air coming into to your snorkel.  Perfect for your overlanding / offroading rig!

Easy to install, no maintenance required.
