EGR Delete Kit
A complete block-off kit for Toyota’s 4.6L port-injected V8, removing the water-cooled, electronically-controlled EGR circuit that lives in the valley of the GX460, Land Cruiser, Tundra and Sequoia.
01Overview
The 1UR-FE routes exhaust gas through a water-cooled EGR cooler and a step-motor EGR valve into the intake manifold, with internal EGR also handled by Dual VVT-i. Over time the EGR passages and valve carbon up, and Lexus has issued a service bulletin (P006A, debris in the EGR assembly) for exactly this on the GX460. Our kit removes the external circuit entirely: clean intake charge, lower intake temperatures, and one fewer thing to clog or leak in the notoriously busy engine valley.
02Why delete it
| Reliability | Eliminates the carbon/debris failure mode behind the P006A MIL and rough-running complaints on 2014-2017 GX460s. |
| Intake cleanliness | Stops sooty exhaust gas from being fed back into the intake tract. |
| Intake temps | Removes a hot-gas path into the manifold for a denser, cooler charge. |
| Swap simplicity | Deletes a whole coolant-and-exhaust subsystem when the engine is transplanted into another chassis. |
| Service access | The EGR sits right on top of the GX460’s known coolant valley-plate leak, which makes it a natural time to address both. |
03Applications
| Lexus GX460 | 2010-2023 |
| Toyota Land Cruiser | 2012-2021 (1UR-FE markets) |
| Toyota Tundra | 2010-2019 (4.6L 1UR-FE) |
| Toyota Sequoia | 2010-2012 (4.6L 1UR-FE) |
| Lexus LS460 / GS460 | Middle-East 1UR-FE spec |
| Engine swaps | Any 1UR-FE transplant, OEM ECU or standalone |
Final year/market coverage confirmed at release.
04What’s in the kit
- [1]EGR block-off plateCNC-machined to the factory EGR-valve mounting face, sealing the exhaust-gas path into the intake manifold.
- [2]Cooler coolant block-offCaps or loops the water-cooled EGR cooler circuit so coolant routing stays sealed and leak-free.
- [3]Gaskets & stainless hardwareEverything needed to seal and torque the plates to spec on the first install.
- [!]ECU path, required on OEM-ECU vehiclesThe step-motor valve is monitored by the factory OBD-II computer, so on a stock truck the kit pairs with an ECU tune (or EGR simulator) to clear the EGR codes. Standalone-managed swaps need nothing extra.
05Electronics & install
Unlike the older 1UZ-FE, the 1UR-FE uses an electronic stepper EGR valve with position feedback, so a resistor trick will not satisfy the ECU. Physically blocking it on a factory-ECU vehicle will set P0401 / P0404 / P006A and a check-engine light until the EGR monitors are disabled with a tune or simulated. Good news: the platform is genuinely tunable, and established shops already flash the GX460 / Land Cruiser / Tundra ECU and TCU. On a swap running standalone engine management, there is no factory ECU to satisfy and the kit is purely mechanical.
