GU Patrol LS1 Panel Filter Airbox – LS Converted - Guard Mounted We’ve been fabricating airboxes for Nissan Patrols for over a decade, and our extensive range of GU and GQ model airboxes fitting Patrols from 1987 through to 1997 is where the Radius Fabrications journey began. These airboxes are a true reflection of our roots in precision TIG welding and performance design. Every Radius Fab airbox is engineered to maximise cold air intake while offering the highest level of protection against dust and water ingress. Whether you’re touring through the Simpson or idling through creek crossings at Eli Creek, our airboxes are designed to perform in the harshest Australian conditions. Pair one with our mandrel-bent stainless snorkels, and you’ll have a setup capable of taking on just about anything nature throws your way. This model uses 4-inch inlet and outlet ports, includes a high-flow Aeroflow filter, and is compatible with most snorkel systems.
