### **Pros and Cons of buying a Kawasaki Vulcan 900 (VN900B) with the Stock Airbox and Air Intake Filter Box (Part Number: 11101-0080, Model Years: 2006 2024)**
#### **Pros**
1. **Stock Reliability and Proven Performance**
The Kawasaki Vulcan 900 has a reputation for being a durable, low-maintenance cruiser with a smooth 903cc parallel-twin engine. The stock airbox and filter are designed to work seamlessly with the engine, ensuring consistent airflow without major modifications. Many owners report few issues with the stock setup over long-term use, especially if the bike is ridden moderately.
2. **Easy Maintenance and Accessibility**
The stock airbox is straightforward to clean or replace. The filter is a simple foam or paper element that can be swapped out every 2,000 4,000 miles (or as recommended by Kawasaki), depending on riding conditions. The design allows for quick disassembly without requiring specialized tools, making it convenient for DIYers.
3. **Cost-Effective Upgrade Path**
If you decide to upgrade the air intake later, the stock airbox provides a solid foundation. Many aftermarket intakes (e.g., K&N, Dyno Dog, or Airohm) are designed to replace or integrate with the stock housing, so you re not locked into a single solution. This flexibility can save money if you wait to modify the bike.
4. **Stock Sound and Character**
The stock airbox contributes to the Vulcan 900 s signature throaty, mid-range growl something many cruiser enthusiasts appreciate. If you prefer the bike s original tone, keeping the stock setup preserves this aspect of its personality.
5. **No Risk of Voiding Warranty (If New)**
If you re buying a new or CPO Vulcan 900, keeping the stock airbox means you won t accidentally void any remaining manufacturer warranty by installing aftermarket parts.
6. **Decent Airflow for Daily Riding**
For casual or commuter use, the stock airbox provides adequate airflow without being overly restrictive. The bike handles well, and the stock setup won t hinder performance in everyday scenarios.

#### **Cons**
1. **Restrictive Airflow Compared to Aftermarket Options**
The stock airbox and filter are designed for reliability and longevity rather than maximum airflow. While they work fine for daily riding, they can limit horsepower and throttle response compared to high-flow aftermarket intakes. If you plan to push the bike harder (e.g., track days, aggressive acceleration), the stock setup will feel underwhelming.
2. **Potential for Dust and Debris Buildup**
The stock filter is effective at trapping particles but can clog more easily than high-quality aftermarket filters (e.g., K&N s washable synthetic fiber). This means more frequent cleaning or replacements, especially in dusty or dirty riding conditions.
3. **Noise and Throttle Lag**
Some riders notice a slight delay in throttle response with the stock airbox, particularly at low RPMs. Aftermarket intakes often reduce this lag by allowing cleaner airflow to the engine.
4. **Limited Customization Appeal**
If you re looking to personalize your bike s sound or performance, the stock airbox is a neutral starting point but lacks the tuning potential of aftermarket options. Many riders opt for intakes like the **Kawasaki VN900B-specific Airohm or Dyno Dog units**, which offer better airflow and a deeper, more aggressive tone.
5. **Potential for Filter Replacement Costs**
While not expensive, replacing the stock filter regularly adds up over time. Aftermarket filters (especially washable ones) can be more cost-effective in the long run, even if they have a higher upfront cost.
6. **Stock Airbox May Feel "Muffled"**
Some riders describe the stock airbox as slightly "boxy" in tone, lacking the growl of a high-flow intake. If you prefer a louder, more aggressive sound, upgrading is a common first modification.
---
### **Conclusion**
The Kawasaki Vulcan 900 s stock airbox and filter box (11101-0080) are a solid, no-frills choice for riders who prioritize simplicity, reliability, and low maintenance. It s an excellent option if you:
- Ride the bike casually or for commuting.
- Prefer the stock sound and character.
- Don t plan to modify the bike aggressively.
- Want to avoid unnecessary upfront costs.
However, if you re looking to enhance performance, throttle response, or the bike s sound, investing in an aftermarket air intake (e.g., **Airohm, Dyno Dog, or K&N**) is a worthwhile upgrade. These modifications are relatively inexpensive and can significantly improve the riding experience, especially for those who enjoy a more aggressive throttle feel.

### **Recommendation**
- **Buy the stock airbox if:**- You re on a tight budget or buying a used bike.
- You ride mostly in urban or light-traffic conditions.
- You don t plan to modify the bike beyond basic maintenance.
- You prefer the stock sound and don t mind slightly restricted airflow.
- **Upgrade to an aftermarket air intake if:**- You want better throttle response and horsepower.
- You ride in dusty or dirty conditions (washable filters are easier to maintain).
- You plan to modify the bike further (e.g., exhaust, ECU tuning).
- You prefer a deeper, more aggressive sound.
- You plan to ride the bike hard (e.g., track days, highway cruising).
**Top Aftermarket Recommendations (for VN900B):**1. **Airohm VN900B Air Intake** Direct-fit, improves airflow, and enhances sound.
2. **Dyno Dog VN900B Intake** Popular for its aggressive tone and performance gains.
3. **K&N High-Flow Air Filter** Washable, reduces restriction, and lasts longer than stock.
4. **BikeMaster VN900B Intake** Budget-friendly but effective for basic upgrades.
If you re buying a new or lightly used Vulcan 900, consider keeping the stock airbox for now and upgrading later if you decide to modify the bike. If you re buying a used bike with high mileage, check the condition of the stock filter if it s dirty or clogged, replacing it with an aftermarket option (like K&N) can immediately improve performance.
So all parts are in good shape, but show signs of wear. These parts are coming off a 2009 Kawasaki Vulcan 9 and it will fit 2006 2024 Vulcan's. The bike was a perfectly good runner.
