1GR Intake Manifold Runner Spacer Kit
Unlock critical low-end performance with this premium intake manifold runner spacer kit. Designed specifically for the Toyota 4.0L V6 (1GR-FE) engine, this direct "bolt-on" modification requires zero engine alterations and reshapes your powerband by extending the intake port airflow path.
By pulling peak performance down into a much lower RPM range, this kit delivers immediate throttle response and quicker acceleration. It is the ideal upgrade for Tacoma and 4Runner owners who navigate challenging off-road terrain, carry heavy overland gear, or simply want maximum power right off the line without having to rev the engine out.
