We've been testing this product for over 1 year with excellent results. We can confidently say that not only does it look good, but it also performs.
Our pre-filter has an internal rotating fan that spins with incoming air to eject dust and debris even before it reaches your air filter. No need to clean this one out, it's working as soon as the engine starts.
USA made, and military tested. Fits our snorkel perfectly.
Made from impact resistant plastic and comes with everything you need to mount it to your Terrawagen snorkel.
