Intake Manifold Spacer Kit | 2000-2004 Tacoma

4-Port Intake Manifold Runner Spacer Kit

Unlock critical low-end performance with this premium intake manifold runner spacer kit. Designed specifically for Toyota 2.4L (2RZ) and 2.7L (3RZ) inline 4-cylinder engines, this "bolt-on" modification requires no major engine alterations and reshapes your powerband by extending the intake port airflow path.

By pulling peak performance down into the idle to mid-range RPM band, this kit delivers immediate throttle response and quicker acceleration. It is the ideal upgrade for Tacoma owners who want maximum power right off the line, better overall drivability, and improved fuel economy (MPG) without having to rev the engine out.

Product Specifications

• Application: Toyota 2RZ and 3RZ 4-port inline-4 engines.
• Vehicle Compatibility: Toyota Tacoma models from 2000 to 2004.
• Powerband Shift: Forces the engine to reach max torque at a lower engine speed, reducing the need for high-RPM operation.
• System Compatibility: Direct fit for the factory OEM airbox and plenum; also compatible with most aftermarket cold air intake systems.
• Emissions Status: Not C.A.R.B. approved (check local regulations regarding emissions compliance).
• Installation Note: Minor adjustments, such as untaping or unclipping factory wiring harness sections, may be required during assembly.
• EGR System Note: If you need to retain a functional Exhaust Gas Recirculation (EGR) system to meet emissions standards, you must also purchase our modified EGR Tube (available separately on our products page). Please allow up to 10 business days for the made-to-order tube to be modified and shipped.
