Airaid 10-14 Toyota 4 Runner / FJ Cruiser 4.0L V6 PowerAid TB Spacer
The POWERAID Throttle Body Spacer is designed to enhance off-idle torque from 800 rpm to approximately 3,000 rpm. The spacer utilizes it's unique, patented Helix Bore design to spin the incoming air charge as it passes through the throttle body spacer. The spinning air action boosts the velocity of the incoming air and contributes to better atomization of the air/fuel mixture as the air charge enters the combustion chamber. The end result is more part-throttle torque and improved mid-range power.Installation InstructionsThis Part Fits: Year Make Model Submodel 2023 Toyota 4Runner 40th Anniversary Edition 2010-2021,2023 Toyota 4Runner Limited 2020-2021 Toyota 4Runner Nightshade 2010-2021,2023 Toyota 4Runner SR5 2018-2021,2023 Toyota 4Runner SR5 Premium 2010-2016,2021 Toyota 4Runner Trail 2017-2021,2023 Toyota 4Runner TRD Off-Road 2018-2021,2023 Toyota 4Runner TRD Off-Road Premium 2015-2021,2023 Toyota 4Runner TRD Pro 2023 Toyota 4Runner TRD Sport 2020-2021 Toyota
