The preferred method is to combine the LLDPE plastic, UV additives and colourant at the compounding stage. The ingredients are well dispersed by slowly bringing the materials to melting point together where they are combined under pressure in a molten state. This process takes longer to complete, but it provides a consistent distribution of the additives therefore providing a more robust polymer.
2) Snorkels are sealed, Airboxes are not.
One of the biggest misconceptions about snorkels is that once you attach them your engine is safe from water ingress. It is more often the case that if you install a snorkel yourself that it is not yet completely waterproof. The snorkel itself is water proof as it is a single piece of plastic however what many forget is that the existing air duct has drainage holes. These holes can easily be filled with silicon to stop any water entering through what was once a way for water to escape. For the best results it is also always a good idea to dab a bit of silicon onto any flat join surfaces to ensure a water tight seal.
3) Are you a DIY person?
When it comes to installing the snorkel are you going to do it yourself or are you going to have someone do it for you? While there are plenty of people that have successfully installed their own snorkels you may not be so handy with the tools. If you’re not going to do it yourself but still want to buy online you should make sure you find someone to install it first. Many 4WD shops won’t install product that hasn’t been bought at their store so try mechanics, panel beaters or mobile fitters as a first port of call.
While we strongly recommend that you do get it installed by a professional we understand that many enjoy working on their own vehicles. It is not uncommon to have to relocate items under the hood of your 4WD. Items such as washer bottles, dual batteries and ignition coils sometimes need to be navigated around or relocated so be prepared to do a bit of custom fabrication.
