Review OEM INFINITI Q45 4.5l Throttle Body Assembly P10 70041 fits 1996

The **Infiniti P10-70041 Throttle Body (1996 Q45, 4.5L Engine)** is a precision-engineered component designed specifically for the high-performance V8 powertrain found in the iconic 1996 Infiniti Q45, a luxury grand touring sedan that seamlessly blends Japanese craftsmanship with European-inspired sophistication. This throttle body, part of the **P10 series**, is a critical element in the engine s electronic fuel injection (EFI) system, responsible for regulating airflow into the intake manifold while working in tandem with the engine control module (ECM) to optimize throttle response, fuel efficiency, and overall performance. Crafted from high-quality materials, including durable plastic and precision-machined metal components, this throttle body is built to withstand the demands of high-revving, high-torque applications characteristic of the Q45 s 4.5-liter V8, which produces a commanding 276 horsepower and 286 lb-ft of torque in its base form. The design incorporates a **pulse-width modulated (PWM) actuator**, allowing for smooth, precise control over throttle opening, which is essential for maintaining a seamless driving experience whether cruising on the highway or accelerating from a standstill. This throttle body is also compatible with aftermarket modifications, making it a popular choice among enthusiasts looking to enhance throttle response, support forced induction setups, or restore performance to stock-like levels after wear and tear. Whether replacing a worn-out original unit or upgrading for improved reliability and responsiveness, this **P10-70041 throttle body** ensures that the Q45 s legendary V8 operates with the efficiency and power it was engineered to deliver, embodying the perfect marriage of luxury and performance that Infiniti intended.

### **Pros and Cons of Buying a 1996 Infiniti P30 (Q45) with a 4.5L Engine and Throttle Body (P10-70041)**

#### **Pros**

1. **Strong Engine and Performance**

The 4.5L V8 (QR45DE) in the Infiniti P30 is a robust, naturally aspirated engine known for its reliability and power output. With proper maintenance, it can produce around 270 300 horsepower, making it capable of handling daily driving and spirited acceleration. The V8 architecture also provides a smooth, engaging driving experience.

2. **Luxury and Comfort**

The P30 was Infiniti s flagship sedan in the late '90s, offering a refined cabin with high-quality materials, comfortable seating, and a spacious interior. It was designed to compete with luxury brands like Lexus and BMW, so it retains a premium feel even today.

3. **Reliability (With Proper Care)**

The QR45DE engine is known for its durability, especially when maintained correctly. Many examples with high mileage (150,000 miles) run well if the engine, transmission, and suspension have been serviced. The 4-speed automatic transmission (R154) is also relatively straightforward and can last long with fluid changes.

4. **Classic Luxury Car Appeal**

The P30 is a sought-after classic luxury sedan, particularly in the U.S. and Europe. Its retro styling, combined with modern V8 power, makes it a unique and desirable car for enthusiasts. Owning one can be a statement of taste and a fun project car.

5. **Mod Potential**

The QR45DE engine is a favorite among tuners due to its strong base and aftermarket support. Upgrades like cold air intakes, performance exhausts, and ECU tuning can enhance power and throttle response. The throttle body (P10-70041) is a common point of failure, but replacing it is a straightforward DIY job.

6. **Availability of Parts**

While some original parts may be hard to find, the QR45DE engine and P30 platform have a strong aftermarket presence. Replacement throttle bodies, sensors, and other components are widely available, making repairs more accessible than on older luxury cars.

7. **Potential for Restoration**

If you re looking for a project car, the P30 can be restored to showroom condition with time and effort. The body is sturdy, and many original parts (like the interior) are still available or can be sourced from junkyards.

#### **Cons**

1. **Throttle Body (P10-70041) Issues**

The throttle body in question (P10-70041) is notorious for failing due to carbon buildup, electrical grease contamination, or internal wear. Symptoms include rough idle, stalling, or hesitation. Replacing it is a common and necessary repair, but it may recur if maintenance is neglected. A new or rebuilt throttle body costs around **$200 $400**, and labor can add to the expense.

2. **Electrical and Sensor Problems**

The P30 is prone to electrical grease contamination, which can cause issues with sensors (like the throttle position sensor, MAP sensor, or crankshaft position sensor). These problems often manifest as check engine lights, rough idling, or drivability issues. Regular cleaning of electrical connectors is essential.

3. **Transmission Wear**

The R154 4-speed automatic transmission is robust but can develop slipping or rough shifting over time, especially if fluid hasn t been changed regularly. A transmission fluid flush (every 60,000 miles) is critical. Rebuilding or replacing the transmission can be costly if it fails.

4. **Suspension and Steering Wear**

The P30 s suspension (struts, bushings, ball joints) and steering components (rack and pinion, tie rods) wear out over time. Hard driving or rough roads can accelerate this. Replacing worn suspension parts improves handling but adds to maintenance costs.

5. **Fuel System Concerns**

The QR45DE engine relies on clean fuel injectors and a functional fuel pump. Carbon buildup in the intake valves and injectors can cause misfires and poor performance. A fuel system cleaning or injector replacement may be needed.

6. **Rust and Body Condition**

Many P30s, especially in snowy or coastal climates, suffer from rust in the wheel wells, rocker panels, and undercarriage. A thorough inspection of the body is necessary to avoid costly repairs down the line.

7. **High Maintenance Costs Over Time**

While the engine is reliable, the P30 is not a low-maintenance car. Regular upkeep (timing belt, spark plugs, fluids, filters) is required to keep it running smoothly. Parts and labor can add up, especially if the car is older and requires specialized service.

8. **Insurance and Registration Costs**

As a luxury classic, insurance for a P30 can be expensive, particularly if it s modified or driven frequently. Some insurers may also charge higher premiums due to its age and value.

9. **Limited Modern Safety Features**

The P30 lacks modern safety features like stability control, advanced airbag systems, or modern crash structures. While it s not unsafe by modern standards, it may not meet today s safety expectations for daily driving.

10. **Market Value and Depreciation**

The P30 is a classic car, but its value doesn t appreciate as quickly as some other luxury sedans (e.g., Lexus LS400). If you re buying it as an investment, expect slow depreciation unless it s in pristine condition.

### **Ending Conclusion**

The **1996 Infiniti P30 (Q45) with a 4.5L engine and throttle body (P10-70041)** is a compelling choice for enthusiasts who appreciate classic luxury, V8 power, and mod potential. It offers a smooth ride, strong performance, and a unique blend of retro styling and modern engineering. However, it requires **attention to maintenance**, particularly with the throttle body, electrical systems, and suspension. If you re prepared for potential repairs and enjoy working on a project car, the P30 can be a rewarding ownership experience.

For someone seeking a **low-maintenance daily driver**, a more modern luxury sedan (e.g., Lexus GS, BMW 5 Series) might be a better fit. But for those who want a **fun, powerful, and stylish classic** with the potential for restoration or tuning, the P30 is an excellent choice **as long as you re willing to invest time and effort into keeping it running**.

### **Recommendation**

- **Buy it if:**

- You re an enthusiast who enjoys working on cars and restoring classics.

- You plan to address the throttle body and other common issues immediately.

- You appreciate the P30 s luxury, V8 power, and mod potential.

- You have a budget for maintenance and potential repairs.

- **Avoid it if:**

- You want a hassle-free, low-maintenance daily driver.

- You re not comfortable with electrical grease contamination or throttle body issues.

- You can t afford unexpected repairs (transmission, suspension, fuel system).

- You prioritize modern safety and technology over classic charm.

**Final Verdict:** The 1996 Infiniti P30 is a fantastic car for the right owner one who values performance, luxury, and the challenge of keeping a classic running. With proper care, it can be a joy to own for years to come.
