Set of 4 Fuel Injectors 35310-2B150 FJ1435 Replacement - Reliable OE

In this review of the Set of 4 Fuel Injectors 35310-2B150 (FJ1435) the bottom line is simple: this kit is for owners of 1.6L L4 Hyundai and Kia models who need a direct, worry-free replacement that matches original equipment specifications. The reviewer found the injectors deliver consistent, balanced fuel delivery and are built from corrosion-resistant composite material with high-temp viton o-rings, which explains why they restore smooth idle and fuel economy without complex tuning or modification.

Key Features

• OE-compatible design: Engineered to match original equipment specifications so installation is straightforward and fitment is predictable for supported models.
• Corrosion-resistant material: Composite construction helps resist wear in the fuel environment and supports longer service life compared with untreated components.
• High-temp viton o-rings: Durable sealing reduces the chance of leaks and maintains consistent fuel pressure under typical operating temperatures.
• Balanced fuel delivery: The injector flow and spray pattern are engineered to restore smooth engine performance and improved throttle response.
• One year after-sales service: The pack includes support for replacements within the warranty period, which adds reassurance after installation.

Who It's For

This set is aimed at drivers of Hyundai Accent (2018-2019), Kia Rio (2018-2019), and Kia Soul (2017-2019) with the 1.6L L4 engine who need a direct replacement for failing injectors and prefer parts that adhere closely to the OE design. It suits DIY mechanics and independent shops that want a straightforward swap without aftermarket calibration or complex adaptions.

It is not intended for turbocharged models, so owners of turbo variants should look for model-specific injectors. Also, if a vehicle requires upgraded flow rates for performance builds, these OE-fit injectors are not a performance upgrade but a like-for-like replacement.

Pros & Cons

Pros

• Direct OE-style fit makes replacement quick and reduces installation troubleshooting.
• Corrosion-resistant composite and viton o-rings improve durability in everyday driving conditions.
• Balanced delivery helps reduce rough idle and can improve fuel economy when replacing degraded originals.

Cons

• Not suitable for turbocharged models, so fitment must be checked carefully before purchase.
• Does not increase flow for performance tuning; intended as a replacement, not an upgrade.
