The **BF0 MTH8DW 2.0L Engine Crankshaft (2017 2020 Hyundai Elantra/Kona)** is a precision-engineered, high-performance replacement part designed to restore optimal power, reliability, and longevity to your vehicle s internal combustion system. Crafted from high-grade forged steel, this crankshaft is built to exacting specifications, ensuring seamless integration with the 2.0L Gamma II (MTH) engine found in the Hyundai Elantra and Kona models from 2017 through 2020. The crankshaft features a robust main journal design with optimized bearing surfaces, reducing friction and minimizing wear while maintaining structural integrity under high RPM and torque loads. Its counterweights are strategically balanced to mitigate vibration, enhancing smoothness and reducing stress on the engine s supporting components, including the bearings, rods, and timing system. Engineered with a durable nitrided surface treatment, this crankshaft resists corrosion and galling, making it ideal for both high-mileage vehicles and those subjected to demanding driving conditions. Whether replacing a worn-out original equipment crankshaft or upgrading for improved performance, this aftermarket part is a direct-fit solution that meets or exceeds OEM standards, ensuring compatibility with the engine s crankshaft position sensor, harmonic balancer, and connecting rods. Built to withstand the rigors of modern driving, this crankshaft is a critical component for restoring engine efficiency, extending component life, and maintaining peak performance in your Hyundai Elantra or Kona.

### **Pros and Cons of buying a BFO MTH8DW 2.0L Engine Crankshaft for 2017 2020 Hyundai Elantra/Kona**

#### **Pros:**

The BFO MTH8DW crankshaft is a popular aftermarket replacement part for the Hyundai 2.0L Gamma (MTH) engine, which powers the 2017 2020 Elantra and Kona. Here are the key advantages:

1. **Improved Durability and Strength** BFO crankshafts are forged from high-quality steel, often with enhanced heat treatment, which can reduce the risk of bending or fatigue failure compared to stock crankshafts. This is particularly beneficial for high-mileage engines or those subjected to aggressive driving.

2. **Better Weight Distribution** Some aftermarket crankshafts, including BFO s, are designed with optimized counterweights to reduce vibration and improve smoothness, which can lead to a quieter and more refined engine operation.

3. **Compatibility and Fitment** BFO crankshafts are engineered to fit the MTH8DW engine specification precisely, ensuring proper alignment with the rod journals, main bearings, and timing components. This reduces the risk of installation errors that could cause damage.

4. **Warranty and Reliability** BFO is a reputable manufacturer with a strong reputation in the aftermarket industry. Their crankshafts come with warranties (typically 1 2 years), providing peace of mind against manufacturing defects.

5. **Potential Performance Benefits** While not a high-performance part, some drivers report slight improvements in engine smoothness and reduced rattling, especially if the stock crankshaft was worn or damaged.

6. **Cost-Effective Alternative to Rebuilding** For engines with minor wear or those that have suffered a crankshaft failure, replacing just the crankshaft (rather than a full engine rebuild) can be significantly cheaper than a complete overhaul.

7. **Easy Installation** Since the crankshaft is a direct replacement, installation is straightforward for those with mechanical experience or when done by a professional. No major engine disassembly is required beyond what s needed for a standard crankshaft swap.

---

#### **Cons:** While the BFO crankshaft offers several benefits, there are also potential drawbacks to consider:

1. **Upfront Cost** Aftermarket crankshafts are more expensive than OEM replacements. For the MTH8DW engine, a BFO crankshaft can cost **$300 $600**, depending on whether it includes bearings, seals, or other components. This is often higher than the cost of an OEM crankshaft (if available) or a used/refurbished one.

2. **No Guarantee of Long-Term Reliability** Even high-quality forged crankshafts can fail if the engine is severely worn, improperly lubricated, or subjected to extreme stress (e.g., forced induction, excessive torque, or lack of maintenance). A crankshaft replacement alone does not address other potential issues like rod bearings, pistons, or connecting rods.

3. **Installation Risks** If not installed correctly, a new crankshaft can cause damage to the engine. This includes improper bearing clearance, misalignment with the rod journals, or failure to torque bolts to specification. This risk applies to both DIY and professional installations.

4. **Limited Performance Gains** Unless the original crankshaft was defective, the BFO part will not significantly improve power or torque. The gains are mostly in durability and smoothness, not performance.

5. **Compatibility Concerns (If Not Exact Fit)** While BFO crankshafts are designed for the MTH8DW, there is a slight chance of fitment issues if the engine has been heavily modified (e.g., custom rods, altered rod lengths, or aftermarket bottom-end components). Always verify compatibility with the engine s specifications.

6. **Warranty Limitations** Most aftermarket warranties (including BFO s) may void if the engine is modified or if installation is not performed correctly. This means the buyer bears responsibility for proper installation and maintenance.

7. **Opportunity Cost** If the engine has other failing components (e.g., rod bearings, pistons, or a worn block), replacing just the crankshaft may lead to repeated failures. In such cases, a full bottom-end rebuild or engine swap might be more cost-effective in the long run.

### **Conclusion and Recommendation**

#### **When to Buy the BFO MTH8DW Crankshaft:**

- **If your engine has a bent or cracked crankshaft** and no other major bottom-end issues, replacing it with a BFO crankshaft is a solid choice. The forged construction and improved balance can extend the engine s life significantly.

- **If you notice excessive vibration, knocking, or oil consumption** that correlates with crankshaft wear, this part is a practical solution before more severe damage occurs.

- **If you plan to keep the engine long-term** and want to avoid future crankshaft failures, the BFO is a reliable upgrade over an OEM part.

- **If you re doing a partial bottom-end rebuild** (e.g., replacing bearings, seals, or rods) and the crankshaft is the only major component showing wear, this is a cost-effective upgrade.

#### **When to Avoid or Consider Alternatives:**

- **If the engine has other severe wear** (e.g., rod bearing failure, piston damage, or a worn block), a crankshaft replacement alone will not fix the underlying issues. In this case, a full rebuild or engine swap is necessary.

- **If you re on a tight budget**, compare the cost of the BFO crankshaft against a used/refurbished OEM crankshaft or a rebuild kit. Sometimes, a used part from a salvage yard can be just as reliable at a fraction of the cost.

- **If you lack mechanical experience**, ensure the installation is done by a trusted mechanic to avoid costly mistakes. Improper installation can lead to catastrophic engine failure.

- **If you re modifying the engine for performance**, consider a high-quality aftermarket crankshaft (like BFO) only if you re also addressing other bottom-end components. A stock crankshaft may not handle forced induction or aggressive tuning well.

#### **Final Recommendation:**

For the **2017 2020 Hyundai Elantra/Kona with a 2.0L MTH8DW engine**, the **BFO crankshaft is a strong aftermarket option** if the original crankshaft is failing or worn. It offers improved durability, better balance, and a reputable warranty, making it a worthwhile upgrade for those who want to extend their engine s life without a full rebuild.

However, **always inspect the rest of the bottom end** (bearings, rods, pistons, and block) before committing. If other components are failing, prioritize addressing those first. If the engine is otherwise healthy, the BFO crankshaft is a **reliable and safe choice** for a long-lasting replacement.

For best results:

- **Buy from a trusted seller** (e.g., BFO s official website, reputable aftermarket parts dealers, or authorized Hyundai/Hyundai Kia parts centers).

- **Have a mechanic verify fitment** before purchase, especially if the engine has been modified.

- **Follow proper installation procedures**, including torque specifications and lubrication.

- **Maintain the engine** with regular oil changes and inspections to ensure the new crankshaft performs as expected.
