This item cannot be shipped to California due to Carb regulation with CA. Automobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels. The ETC system (Electronic Throttle Control) – also known as drive-by-wire – has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gear changes, overtaking, etc. The Sprint Booster aims to overcome this throttle response delay for ETC-equ ipped vehicles, providing crisp on-tap acceleration at the driver's disposal.This Part Fits: Year Make Model Submodel 2010-2022 Toyota 4Runner Limited 2020-2021 Toyota 4Runner Nightshade 2010-2022 Toyota 4Runner SR5 2018-2022 Toyota 4Runner SR5 Premium 2010-2016,2021-2022 Toyota 4Runner Trail 2017-2022 Toyota 4Runner TRD Off-Road 2018-2022 Toyota 4Runner TRD Off-Road Premium 2015-2022 Toyota 4Runner TRD Pro 2022 Toyota 4Runner TRD Sport 2020-2021 Toyota 4Runner Venture
