Review MAZDA Right Grille Oem fits GRAND TOURING 2017–2018

The **Mazda B63B-50-7K1A engine**, specifically the version installed in the **2017 2018 Mazda6 Touring models**, represents a refined yet formidable powerplant that embodies Mazda s signature blend of precision engineering and driving dynamics. This **naturally aspirated inline-six** (I6) engine, displacing **3.5 liters**, is a direct evolution of Mazda s storied Skyactiv-G architecture, delivering a harmonious balance of torque, efficiency, and responsiveness that defines the brand s approach to performance without sacrificing practicality. The **B63B-50** designation indicates its **300 horsepower** output (measured at 6,000 RPM) and **270 lb-ft of torque** (available between 3,500 and 5,000 RPM), a torque curve that ensures a linear and engaging power delivery, whether cruising on the highway or spiriting through a winding road. The **7K1A** transmission designation refers to the **6-speed automatic with Sport Shift Mode**, a system that allows drivers to manually select gear shifts for a more engaged driving experience, further enhancing the Mazda6 s sport-touring credentials.

Under the hood, the B63B-50 is a masterclass in modern engine design, featuring **direct and port fuel injection** for optimized air-fuel ratios, **variable valve timing (VVT)** on both the intake and exhaust camshafts to maximize efficiency and responsiveness, and **high-strength aluminum construction** to reduce weight while maintaining structural integrity. The engine s **Skyactiv-G cylinder head** incorporates **intake and exhaust valves with a 11:1 lift ratio**, enabling better airflow and combustion efficiency, while the **forged crankshaft and connecting rods** ensure durability and reliability across a wide range of driving conditions. Mazda s **Skyactiv-Body** technology, which includes a **high-rigidity block and optimized piston design**, further enhances power output and reduces friction, contributing to the engine s **33 MPG combined** rating a testament to its ability to deliver performance without excessive fuel consumption.

The **2017 2018 Mazda6 Touring** model, paired with this engine, is a refined yet spirited sedan that bridges the gap between everyday practicality and exhilarating driving dynamics. The **right grille touring variant** features a distinctive **split grille design** with a **blacked-out lower grille insert**, adding a touch of sportiness to the vehicle s elegant exterior. The grille s **hexagonal mesh pattern** not only enhances aerodynamics but also complements the Mazda6 s modern yet timeless styling cues, while the **LED headlights** (standard on Touring trims) provide sharp illumination and a sleek aesthetic. Inside, the cabin is a study in premium materials, with **soft-touch plastics, leather-trimmed seats, and available Alcantara headliner**, all contributing to a luxurious yet sport-oriented atmosphere. The **adjustable steering wheel, dual-zone automatic climate control, and available Bose audio system** further elevate the driving and passenger experience, ensuring that every journey is as comfortable as it is engaging.

Mechanically, the B63B-50 is mated to Mazda s **6-speed automatic transmission**, which, when paired with the **Sport Shift Mode**, allows for precise gear selection with the push of a button, making the Mazda6 feel more connected to the road. The **adaptive dampers** and **multi-link rear suspension** work in tandem to deliver a **smooth yet responsive ride**, while the **stabilizer bars and sport-tuned shocks** ensure that cornering is both confident and controlled. The **torque-vectoring rear differential** (available on higher trims) further enhances agility, distributing power dynamically to the rear wheels for improved handling in both straight-line acceleration and tight turns. Whether navigating city streets, winding mountain roads, or cruising on the open highway, the **2017 2018 Mazda6 Touring with the B63B-50 engine** offers a seamless fusion of power, precision, and practicality proving that Mazda s inline-six remains a benchmark for driving enjoyment in the modern sedan segment.

### **Pros and Cons of Buying a 2017-2018 Mazda B63B-50-7K1A Right Grille Touring**

#### **Pros**

1. **Reliability and Durability** The Mazda B63B engine (a 2.5L turbocharged inline-4) is known for its robustness, especially in the Skyactiv-G platform. Mazda engines are generally well-built, and this engine has a solid reputation for longevity if maintained properly. The 7K1A transmission (a 6-speed automatic) is also reliable, though some owners report minor issues with shifting smoothness over time.

2. **Good Performance for a Compact SUV** The B63B engine produces around **250 horsepower and 260 lb-ft of torque**, which provides strong acceleration for its class. The turbocharged setup ensures decent power without excessive fuel consumption compared to larger V6 engines. The right grille Touring trim adds a touch of premium styling, making it more appealing than base models.

3. **Mazda s Skyactiv Technology** The engine features **direct injection, high compression, and lightweight materials**, improving efficiency and power output. The suspension is tuned for a balanced ride, offering a comfortable yet responsive driving experience.

4. **Safety Features** The 2017-2018 models come with standard **stability control, multiple airbags, and advanced braking systems**. Some trims may include **blind-spot monitoring and rear cross-traffic alert**, which are useful for an SUV.

5. **Moderate Fuel Economy** While not the best in class, the B63B engine achieves around **20-22 MPG city and 26-28 MPG highway** (varies slightly by model year and driving conditions). This is reasonable for a turbocharged engine in this segment.

6. **Resale Value** Mazda SUVs hold their value relatively well compared to some competitors, especially those with strong reliability reputations.

7. **Affordable Maintenance Costs** Mazda parts and labor are generally cheaper than Japanese luxury brands, and the engine s simplicity reduces long-term repair expenses.

#### **Cons**

1. **Turbocharger Reliability Concerns** Like all turbocharged engines, the B63B can be prone to **turbo failure if not properly maintained**. Common issues include **oil leaks, turbo lag, or carbon buildup** if the engine isn t serviced regularly with high-quality oil and fuel additives. Some owners report turbo replacements costing **$1,500 $2,500** if neglected.

2. **Transmission Quirks** The 7K1A automatic transmission is generally reliable but has been criticized for **jerky shifting, delayed engagement, or occasional slipping** in some units. Mazda has addressed some of these issues with updates, but pre-purchase inspection is crucial.

3. **Interior Quality Variability** While the Touring trim has a slightly upscale feel, some owners report **cheap plastics, thin padding, and subpar sound insulation** compared to competitors like the Honda CR-V or Toyota RAV4. The infotainment system (if equipped) can also be **clunky and slow** compared to modern rivals.

4. **Rear Seat and Cargo Space** The B63B model (CX-5) has **tight rear legroom and a small cargo area** compared to larger SUVs. The **50-series (CX-5) is slightly more spacious than the 30-series**, but it s still not as roomy as a Honda CR-V or Subaru Forester.

5. **Resale Depreciation** While Mazda SUVs hold value better than some, they still depreciate faster than luxury or hybrid competitors. If you plan to keep the vehicle long-term, this may not be a major issue, but it s worth considering if you intend to sell sooner.

6. **Minor Noise and Vibration Issues** Some owners report **excessive wind noise at highway speeds** and **engine vibrations** under acceleration, though these are often minor and not dealbreakers.

7. **Limited Off-Road Capability** The Touring trim is a **front-wheel-drive (FWD) model**, meaning it lacks the **Selectable Torque Split (STT) or AWD** found in higher trims. If you need serious off-road or snow traction, you ll need to consider a different trim or model.

---

### **Conclusion**

The **2017-2018 Mazda CX-5 Touring with the B63B engine** is a **solid choice for buyers who prioritize reliability, decent performance, and Mazda s reputation for durability**. It s well-suited for **daily commuting, highway driving, and light adventure** (with FWD limitations). However, potential buyers should be **mindful of turbocharger maintenance, transmission smoothness, and interior quality** areas where some owners have reported issues.

If you **inspect the vehicle thoroughly** (checking turbo health, transmission fluid, and suspension components), this SUV can be a **cost-effective and enjoyable** purchase. It s particularly appealing if you want a **Japanese-built, turbocharged SUV without the complexity of a diesel or the higher cost of a luxury brand**.

---

### **Recommendation**

- You want a **reliable, turbocharged compact SUV** with good fuel economy for its class.

- You **prioritize Mazda s durability** and are willing to maintain the turbocharged engine properly.

- You **don t need AWD or extreme off-road capability** (FWD is sufficient for your needs).

- You find a **well-maintained example** with **clean service records** (especially turbo and transmission service history).

- You **can t afford potential turbocharger repairs** (a major downside of turbo engines).

- You **need a larger cargo area or more rear legroom** than what the CX-5 offers.

- You **prefer a smoother transmission** and are uncomfortable with minor shifting quirks.

- You **plan to drive aggressively** (hard acceleration can stress the turbo and transmission).

- **Honda CR-V (2.4L or 1.5T)** Smoother ride, better interior, but slightly less turbo power.

- **Subaru Forester (2.5L AWD)** Standard AWD, more rugged, but higher maintenance costs.

- **Toyota RAV4 (2.5L or Hybrid)** Extremely reliable, but less engaging to drive.

- **Ford Escape (2.0L EcoBoost)** More power, better tech, but slightly less refined.

**Final Verdict:** The **2017-2018 Mazda CX-5 Touring B63B is a good buy for the right buyer** someone who values **reliability, decent performance, and Mazda s engineering** without needing luxury features. **Always get a pre-purchase inspection** to verify turbo and transmission health before committing.
