Review PONTIAC Trunk/hatch/tailgate Spoiler 88-91 fits BONNEVILLE 1989

The **Pontiac 170-01319A Trunk/Hatch/Tailgate Spoiler** is a meticulously crafted aftermarket accessory designed to enhance the aggressive, sport-tuned aesthetic of 1988 through 1991 Bonneville models, particularly those equipped with the iconic L67 V8 engine or other high-performance variants. This high-quality fiberglass spoiler is engineered to seamlessly integrate with the rear deck of your Bonneville, offering both a striking visual upgrade and subtle aerodynamic benefits. Crafted from durable, weather-resistant materials, the spoiler features a sleek, contoured design that follows the natural contours of the trunk lid, ensuring a clean, factory-like appearance without the bulkiness of aftermarket alternatives. Its aerodynamic shape not only improves downforce at higher speeds but also reduces lift, contributing to better handling and stability ideal for those who appreciate both style and performance. The spoiler s matte black finish is resistant to fading, chipping, and environmental wear, making it a long-lasting investment that complements the classic yet bold personality of the Bonneville. Whether paired with a stock or heavily modified suspension setup, this spoiler adds a touch of sophistication and presence, transforming your Bonneville into a statement piece that turns heads on the road. Perfect for enthusiasts who seek a balance between heritage charm and modern performance enhancements, the 170-01319A is a must-have for any Bonneville owner looking to elevate their vehicle s look while maintaining functionality.

### **Pros and Cons of buying a Pontiac 170-01319A Trunk/Hatch/Tailgate Spoiler (1988 1991 Bonneville)**

#### **Pros**

1. **Improves Aerodynamics and Fuel Efficiency** The spoiler reduces drag, which can slightly improve fuel economy, especially at highway speeds. This is particularly noticeable on larger, heavier vehicles like the Bonneville.

2. **Enhances Styling and Personalization** The Bonneville was a luxury-oriented car, and adding a spoiler gives it a more sporty or performance-oriented look. This can be appealing if you want to modify the vehicle s appearance.

3. **Potential Performance Benefits** While the impact on handling is minimal, a properly installed spoiler can help stabilize the car at high speeds, reducing lift and improving traction.

4. **Aftermarket Availability and Compatibility** This specific spoiler (170-01319A) is designed for the 1988 1991 Bonneville, meaning it fits without major modifications. It s also a relatively common part, making it easier to find and install.

5. **Durability** Pontiac spoilers from this era were typically made of fiberglass or reinforced plastic, which are durable materials that can withstand minor impacts and weather exposure.

6. **Easy Installation** Since it s an OEM (original equipment manufacturer) part, it should fit without extensive cutting or welding, though some adjustments may still be needed depending on the vehicle s condition.

7. **Resale Value Boost (If Installed Properly)** If the Bonneville is a collector s item or a well-maintained classic, a correctly installed spoiler can enhance its appeal to enthusiasts who appreciate period-correct modifications.

#### **Cons**

1. **Limited Performance Impact** The Bonneville was not a high-performance car, and the spoiler s aerodynamic benefits are modest. If you re looking for significant handling improvements, this part alone won t deliver them.

2. **Potential for Poor Fitment** Even though it s an OEM part, the spoiler may not align perfectly with a modified or heavily restored Bonneville. Rust, frame damage, or aftermarket bodywork could require additional labor to install it correctly.

3. **Weight Addition** The spoiler adds noticeable weight to the rear of the vehicle, which could slightly degrade acceleration and braking performance, especially if the suspension is already worn.

4. **Maintenance and Wear** Over time, the spoiler may develop cracks, delamination, or peeling paint due to UV exposure or minor impacts. Fiberglass and plastic parts require occasional touch-ups to maintain their appearance.

5. **Cost Considerations** While not extremely expensive, the spoiler itself may cost between $100 and $300, depending on condition and source. Installation could add another $50 $150 if you re not doing it yourself.

6. **Aesthetic Mismatch Risk** Some Bonneville owners prefer a more classic or minimalist look. A spoiler may clash with the vehicle s original design intent, especially if the car is restored to factory condition.

7. **Reliability of Used Parts** If purchasing a used spoiler, there s a chance it may have been damaged or improperly stored, leading to warping, cracks, or poor paint quality.

### **Conclusion**

The **Pontiac 170-01319A spoiler** is a practical and stylish addition for a 1988 1991 Bonneville, particularly if you value aerodynamics, a sportier appearance, or period-correct modifications. Its benefits are most noticeable in fuel efficiency and rear-end stability, though its impact on performance is minor. The spoiler is relatively easy to install and widely available, making it a low-risk upgrade for enthusiasts who want to enhance their vehicle s look without major modifications.

However, it s not a critical part meaning the car will function perfectly fine without it. If you re restoring the Bonneville to factory condition, the spoiler may not be necessary. On the other hand, if you re modifying the car for personal preference or driving enjoyment, it s a worthwhile addition that adds both function and flair.

---

### **Recommendation**

- You want to improve the Bonneville s aerodynamics slightly and give it a more aggressive stance.

- You re restoring the car with aftermarket modifications and want a period-appropriate upgrade.

- You re comfortable with a minor installation project (or have a mechanic do it for you).

- The spoiler fits within your budget and aligns with your aesthetic goals.

- You re restoring the Bonneville to factory condition and prefer a clean, original look.

- You prioritize performance over aesthetics and have better ways to improve handling (e.g., suspension upgrades).

- The cost or installation effort doesn t justify the minimal benefits.

- You re unsure about the fitment due to prior bodywork or structural issues.

For most Bonneville owners who appreciate classic luxury with a touch of sportiness, the **170-01319A spoiler is a solid choice** especially if you find a high-quality, undamaged unit. Just ensure it s installed correctly to avoid alignment or fitment issues.
