The aFe Power Sprint Booster Power Converter, part number AFE77-16509, is designed for select 2010-2018 Toyota 4Runner models equipped with the V6 4.0L engine. Modern vehicles use an electronic throttle control system, also known as drive-by-wire, to translate accelerator pedal movement into electronic signals. While this technology supports precise engine management, it can also create a noticeable delay between pedal input and throttle response. The Sprint Booster helps reduce that delay for a more immediate and responsive driving experience.
By optimizing the electronic throttle signal, the aFe Power Sprint Booster gives drivers improved control during everyday acceleration, uphill starts, quick gear changes, merging, and passing. Its response-focused design helps deliver crisper throttle action without requiring permanent engine modifications or complicated tuning. The converter features three position settings, allowing the driver to select the response level that best suits driving conditions and personal preference. This makes it a practical upgrade for drivers seeking sharper acceleration and a more engaging feel from their Toyota 4Runner.
Installation is designed to be straightforward, using the vehicle’s existing electronic throttle connection and requiring no major disassembly. The compact plug-in design helps simplify installation and allows the system to be added without altering the factory throttle pedal assembly. The aFe Power Sprint Booster is intended for off-road and racing applications where applicable and is not CARB approved for use on emissions-controlled vehicles in California. Verify vehicle year, engine configuration, and regional emissions requirements before ordering.
