Kia Forte5 Ignition Coil Guide: 2020-2024 Models
Dealing with a rough idle or check engine light on your Forte5? Your ignition coils could be the culprit.
- A flashing check engine light indicates a serious misfire; avoid driving to prevent catalytic converter damage.
- For high-mileage cars (>60k miles), replacing all four coils at once is a smart preventative measure.
- The replacement is very DIY-friendly, requiring only basic tools and about 30 minutes.
- Verify the correct part number for your Forte5's 1.6L Turbo engine (likely 27301-2B120) before ordering.
Is Your Kia Forte5 Ignition Coil Failing?
Ignition coils are wear-and-tear items. Heat and vibration from the engine eventually cause them to break down. For the 2020-2024 Kia Forte5, especially with the 1.6L turbo engine, a faulty coil is a common reason for a decline in performance. When a coil starts to fail, it won't deliver enough voltage to the spark plug, leading to incomplete combustion. This can cause a variety of symptoms.
Key Failure Symptoms:
- Engine Misfires: The most common symptom. Your engine may sputter, shake, or hesitate, especially when accelerating or idling.
- Check Engine Light: A failing coil will almost always trigger the check engine light. The code will typically be P0300 (random misfire) or P0301, P0302, P0303, P0304, indicating a misfire in a specific cylinder.
- Rough Idle: Your car may vibrate or shudder when stopped at a light.
- Poor Acceleration: You'll notice a lack of power when you try to speed up.
- Reduced Fuel Economy: When fuel isn't burned properly, your gas mileage will suffer.
Known Issues & Recalls
As of early 2026, there are no active recalls or widespread Technical Service Bulletins (TSBs) specifically for ignition coil failure on the 2020-2024 Kia Forte5. However, earlier Forte models (2017-2018) did experience coil issues that led to updated parts from Kia. This suggests that choosing a quality replacement is important.
Choosing the Right Aftermarket Ignition Coil
You don't have to buy the part from the Kia dealer. Aftermarket coils can offer the same performance for less money, but quality varies. Here’s a breakdown of the brands available.
Tier 1: Premium & OEM-Equivalent Brands
These brands are known for manufacturing parts for automakers directly or having a reputation for quality that meets or exceeds the original equipment.
- NGK: A top choice for ignition components. NGK is a well-respected brand with a long history of making high-quality ignition parts that often exceed OEM standards.
- Hitachi: Another major OEM supplier. Hitachi coils are known for their reliability and durability, making them a safe and dependable choice.
Tier 2: Quality Aftermarket Brands
These brands focus on the aftermarket but aim to provide OE-level fit and function. They are a solid choice for a balance of price and quality.
- Spectra Premium: A widely available aftermarket brand that offers a cost-effective alternative. While generally reliable, quality can sometimes be inconsistent compared to premium brands.
- Holstein: Holstein markets its coils as meeting or exceeding OE specifications and backs them with a 3-year/36,000-mile warranty, which is a good indicator of quality.
- Walker Products: Positions itself as an OE-grade replacement and is a well-known name in the aftermarket.
Tier 3: Economy Brands
These brands offer the lowest price, but may not have the same longevity or rigorous quality control as higher-tier options. They can be a solution for budget-focused repairs.
- URO Parts: Generally known as a budget-friendly brand for European cars, they also offer parts for other vehicles.
- Global Parts: A general aftermarket brand that falls into the economy category.
Pro Tip: Replace in Sets?
Ignition coils are exposed to the same conditions. If one fails, the others may not be far behind. If your Forte5 has higher mileage (over 60,000 miles), it's wise to replace all four coils at once to prevent future failures and ensure balanced engine performance. While you're there, it's also the perfect time to inspect or replace your spark plugs.

Frequently Asked Questions
Is it hard to replace the ignition coils on a 2020-2024 Kia Forte5?
No, it is a very easy job for a DIYer. The coils are located directly on top of the engine. The process involves removing the plastic engine cover, disconnecting the electrical connector, removing one 10mm bolt, and pulling the coil straight out. It typically takes less than 30 minutes.
What are the OEM part numbers for the ignition coils?
The Kia Forte5 in this generation primarily uses the 1.6L Turbo engine. However, some Forte models use a 2.0L engine. Always verify with your VIN, but common part numbers are:
- 1.6L Turbo Engine: 27301-2B120
- 2.0L Engine: 27300-2E601
Should I use dielectric grease when installing new coils?
Yes. Applying a small amount of dielectric grease to the inside of the coil boot before installing it on the spark plug helps protect against moisture and ensures a good connection. It also makes it easier to remove the coil in the future.
Can I just replace the one bad coil?
Yes, you can. If your car has low mileage, replacing only the failed coil is acceptable. However, for cars with over 60,000 miles, it is recommended to replace all of them as a set to ensure reliability and consistent performance.
