aFe 90MM Throttle Body

2013–2023 Chrysler 300 / Dodge Challenger 5.7L Hemi & 6.4L 392

Part #: 46-39107

Overview

The aFe 90MM Throttle Body Kit is a high-performance upgrade designed specifically for 2013 to 2023 Chrysler 300 and Dodge Challenger models equipped with the 5.7L Hemi or 6.4L 392 engines. This throttle body replaces the factory 80mm unit with a larger 90mm bore, allowing for increased airflow into the engine. The result is improved throttle response and enhanced horsepower potential, especially when combined with other performance modifications.

Engineered for enthusiasts seeking a reliable, bolt-on solution, this throttle body kit requires no tuning and features plug-and-play electronics for a seamless upgrade. It is an ideal choice for those looking to maximize their vehicle’s performance without complicated installation or calibration.

Key Features

This aFe throttle body kit offers several advanced features that contribute to its performance and ease of use:

• 90mm bore diameter for increased airflow compared to the stock 80mm throttle body
• No tuning required—plug-and-play electronics ensure hassle-free integration
• Billet aluminum adapter crafted from 6061-T6 for strength and lightweight durability
• Direct bolt-on design using factory mounting points for simple installation
• Includes gasket and all necessary hardware for a complete installation
• Serrated and swirl design in the adapter promotes intake turbulence for improved combustion efficiency
• Compatible with 2013–2023 Chrysler 300 and Dodge Challenger 5.7L Hemi and 6.4L 392 engines
• Recommended for use with aFe cold air intake systems to maximize performance gains

Construction & Design

The throttle body adapter is precision-machined from premium 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio and corrosion resistance. This high-quality material ensures durability under demanding engine conditions while maintaining a lightweight profile. The adapter’s serrated and swirl combination design enhances air intake dynamics by creating turbulence that helps atomize fuel more effectively, leading to a more complete combustion cycle. This engineering detail contributes to increased horsepower, torque, and throttle responsiveness.

Performance & Sound

By increasing the throttle body bore size from 80mm to 90mm, this aFe throttle body significantly improves airflow into the engine. This upgrade enhances throttle response, allowing the engine to react more quickly to driver input. While the primary focus is on performance gains, users may also notice a subtle improvement in engine sound due to the increased air volume moving through the intake system. Performance improvements become more pronounced when paired with other modifications such as cold air intakes and exhaust upgrades.

Installation & Fitment

The aFe 90MM Throttle Body Kit is designed for a direct bolt-on installation using all factory mounting locations, ensuring a secure and stable fit. Installation is straightforward and does not require any tuning or complex adjustments, thanks to the plug-and-play electronic throttle control compatibility. This kit is compatible with 2013 through 2023 Chrysler 300 and Dodge Challenger models equipped with the 5.7L Hemi or 6.4L 392 engines. It is important to note that this throttle body will not fit 2005–2012 models due to a different throttle position sensor (TPS) connector.

For optimal performance, it is recommended to install this throttle body in conjunction with an aFe cold air intake system.
