Trade discounts available for bulk orders ---------------------------------------------------------------------------------------------------- Water Crossing, Air Filtration, Inspection & Maintenance Guide IMPORTANT NOTICE The GrenX Snorkel and Airbox System is designed to reduce the risk of water, dust and debris entering the engine intake system. It is not a submarine kit, does not make the vehicle waterproof and does not eliminate the need for proper driver judgement, vehicle maintenance, safe recovery planning or compliance with vehicle manufacturer instructions. Purpose The GrenX Snorkel and Airbox System improves intake protection while maintaining high airflow and serviceability for touring, off-road and expedition use. The integrated drain valve assists drainage of incidental water entering the airbox during normal operation. During installation use Loctite 248 for all silicon connections & screws. Why the GrenX Airbox Includes a Drain Valve & Viewing Window Unlike many snorkel systems that rely solely on sealing, the GrenX Airbox includes a drain valve and visual inspection window. The drain valve allows incidental water drainage while the viewing window provides rapid inspection after water exposure. River Crossings & Deep Water Before entering water crossings, close the airbox drain valve and activate the manufacturer's wading mode where equipped. After the crossing, re-open the drain valve and inspect the airbox through the viewing window. The drain valve is intended as an emergency safeguard, not permission to exceed vehicle limits. Water Crossing Preparation Assess crossing depth, flow, entry and exit points, recovery options and hazards. Ensure diff, transmission and transfer case breathers are functioning correctly. GrenX recommends extended breathers. Avoid entering deep water immediately after heavy towing, highway driving or hard use; allowing components to cool may reduce thermal shock and seal- related water ingress risks. Vehicle Recovery Considerations If the vehicle becomes immobilised in water, do not restart the engine until the intake system has been inspected. Owners should note that a Grenadier may require access to the transmission neutral disengagement mechanism located underneath the vehicle. This may be inaccessible in flooded conditions, making recovery planning essential before entering water. Water Crossing Technique Enter slowly and maintain steady throttle. Avoid sudden acceleration, harsh braking, rapid steering inputs and unnecessary gear changes. Follow the safest route and maintain a controlled, consistent speed appropriate for conditions. Vehicle Modifications & Water Crossings Larger tyres and suspension modifications may increase practical ground clearance but do not eliminate water crossing risks. Always refer to the vehicle manufacturer's published specifications and assess conditions carefully. Cabin Water Ingress If water enters the cabin, evacuate it as soon as practical. The Grenadier is equipped with floor drain valves that should be opened when safe to minimise damage to carpets, trim and electrical systems. Air Filtration & Dust Management GrenX does not recommend oiled air filters due to potential sensitivity of the BMW engine management and MAF sensor system. GrenX recommends a dry filter element. Performance filters designed primarily for airflow and horsepower may be suitable for road use but may not provide the filtration efficiency required for severe off-road conditions. Engine protection should take priority over maximum airflow. An engine can tolerate minor airflow restriction far better than dust contamination. GrenX Dry Filter Element The GrenX Airbox is designed around a high-quality dry filter element. Carrying a spare filter is recommended for remote touring and dusty environments. Dust Socks & Pre-Filters External snorkel socks or pre-filters may provide additional protection during extended dusty travel. They should be inspected and cleaned regularly. Excessively dirty socks may restrict airflow and negatively affect performance. Post-Crossing Inspection After significant water crossings, re-open the drain valve, inspect the viewing window, inspect the filter if water ingress is suspected, check for warning lights, inspect snorkel openings for debris and inspect driveline breathers. If water is visible or suspected, do not operate the vehicle until the intake system has been inspected. Viewing Window Inspection The viewing window is intended as a rapid inspection aid only and does not replace direct inspection when contamination or water ingress is suspected. Importance of the Airbox Cover Plate The GrenX airbox cover plate is a critical component designed to distribute clamping pressure evenly across the inspection viewing window. This even load prevents ensures the airbox seal is compressed uniformly around its entire perimeter. When servicing the airbox, the cover plate fasteners should be tightened gradually in an even sequence. Tightening one side fully before the others can create uneven pressure, potentially compromising the seal. Correct installation ensures the airbox remains fully sealed, maintaining maximum filtration performance and protecting the engine from dust and water ingress. Initial Inspection After Installation Inspect the snorkel system after approximately 500 km and during the next scheduled service. Verify bracket alignment, fastener security, hose clamp tightness and sealing integrity. Periodic Inspection & Maintenance Inspect the snorkel system during routine servicing, after major trips, corrugated roads, impacts, significant water crossings or whenever unusual intake behaviour is observed. Vehicles used in dusty environments should be inspected more frequently. Snorkel Impact Inspection After impacts with branches, vegetation, recovery equipment or obstacles, inspect for cracks, distortion, movement, damaged seals, loose fasteners and air leaks. Installer Responsibility Correct installation is critical. The installer is responsible for ensuring all snorkel, airbox, ducting, hose, clamp and sealing connections are correctly assembled and appropriately sealed. The installer must verify system integrity after installation. Driver Reminder Before water crossings: close drain valve, activate wading mode, assess depth and recovery options. After crossings: open drain valve, inspect the viewing window and check for signs of water ingress. Quick Reference Normal driving: Drain valve OPEN. Vehicle washing: OPEN. Heavy rain: OPEN. Dusty conditions: OPEN. River crossings: CLOSED. After crossing: OPEN and inspect viewing window. Warranty & Disclaimer Failure to inspect and maintain the snorkel system may reduce performance and affect warranty eligibility. No snorkel system can guarantee protection from engine damage, water ingress, recovery costs, vehicle damage or component failure. The vehicle owner and driver remain responsible for operation, inspection and maintenance. Thank You Thank you for supporting this community-funded project.
