Short Answer: Air suspension for the Infiniti G37 improves ride quality, adjustability, and performance by replacing traditional coil springs with airbags. It allows drivers to customize ride height, stiffness, and comfort on demand. Benefits include improved handling, enhanced aesthetics, and adaptability for daily driving or show purposes. Installation costs range from $2,500 to $6,000, depending on components and labor.
What Maintenance Do G37 Air Suspension Systems Require?
Monthly inspections of air line connections and compressor functionality are critical. Moisture traps in the air system must be drained seasonally to prevent corrosion. Air springs should be checked for microfractures every 15,000 miles. Using silicone-based lubricants on moving parts reduces wear. Winter drivers should apply anti-ice treatments to prevent valve blockages in subzero temperatures.
Proper maintenance significantly extends system lifespan. Owners in coastal regions should rinse air components weekly to combat salt corrosion, while high-mileage users benefit from quarterly pressure sensor calibrations. Diagnostic scans using OBD-II adapters can detect early signs of compressor wear by monitoring amp draw fluctuations. Many modern kits feature self-sealing air lines that automatically isolate leaks, but manual inspections remain essential for critical components like the tank mounts and electrical relays.
| Component | Maintenance Interval | Recommended Action |
|---|---|---|
| Air Compressor | Every 3 Months | Clean intake filter, check mounting bolts |
| Air Lines | Annually | Pressure test at 200 PSI |
| Height Sensors | Every 15k Miles | Re-calibrate using manufacturer software |
How Do You Customize Air Suspension for Show vs. Daily Driving?
Show configurations prioritize ultra-low static modes (0-1″ ground clearance) using slam valves for rapid deflation. Daily setups maintain 3-4″ clearance with softer damping profiles. Advanced systems offer GPS-linked presets – automatically raising suspension near remembered speed bumps or lowering at frequent highway on-ramps. Pressure sensors can adjust stiffness based on passenger load for consistent ride quality.
Is air suspension better than shocks?
Enthusiasts building show cars often install dual-path systems with separate presets for display and transport modes. Display mode might incorporate “dynamic bounce” features that cycle the suspension for visual effect, while transport mode maintains sufficient clearance for trailer loading. For daily drivers, progressive controllers gradually stiffen damping as speed increases, combining comfort at city speeds with stability during highway merges. Some systems integrate with smartphone apps to track real-time pressure data and geofence automatic height adjustments.
| Use Case | Ideal Pressure (PSI) | Recommended Height |
|---|---|---|
| Car Shows | 5-15 PSI | 0.5″ ground clearance |
| Daily Commute | 35-45 PSI | 3.2″ ground clearance |
| Performance Driving | 50-60 PSI | 2.0″ ground clearance |
“Modern air suspension bridges the gap between luxury comfort and track-ready performance in the G37. The latest systems use predictive algorithms that analyze road surfaces 200 meters ahead via camera inputs, proactively adjusting damping rates. We’re seeing 30% longer component lifespans in Gen 4 kits compared to 2010-era designs.” – Senior Engineer, Aftermarket Suspension Manufacturer
FAQs
- Does air suspension ruin the G37’s ride quality?
- Properly tuned air suspension improves ride quality by allowing variable damping rates. In Comfort mode, it absorbs bumps better than OEM shocks while Sport mode reduces body roll by 40% compared to stock setups.
- Can I install air suspension on a G37x AWD model?
- Yes, but require modified front struts to clear the AWD system’s transfer case. Expect 15% higher installation costs compared to RWD models due to additional disassembly requirements.
- How long do air springs typically last?
- Quality air springs endure 80,000-120,000 miles under normal use. Harsh weather climates may reduce lifespan to 50,000 miles. UV-resistant covers and monthly rubber conditioner applications extend longevity.
