How to order:

We got a small supply of the EGR Delete Kits delivered recently from our machinist. I don’t know how many more we’re going to get as they keep increasing the production cost.

The total cost, shipped within the USA is $99. If you want one, please send a $49 deposit to me via PayPal at [email protected]. I’ll reserve one for you and then when the kit is packaged up and ready for shipment, I’ll email instructions for the remaining balance. We’ve been shipping these out within 24-36 hours from California. (If you’re outside the USA, there will be $20 additional shipping.)

Installation is extremely straight-forward and the included instructions are clear but if you need additional help, just email me! Lextreme customers have been extremely happy with their results. This is the quickest, easiest and most important mod available for the 1UZFE, bar none!

About the kit:

The EGR block-off plates are for the 1990-1994 Lexus LS400 and 1992-1996 SC400.  (We’ve been told that they do work on 1995, 1996 and 1997 1UZFE Models but need a little modification. We’re working on a kit specifically for those models but if you have a little ingenuity, this will work with a slight modification!)

These high quality CNC machined mild steel plates were designed by engineers and will allow you to completely remove the EGR system.

Why is this really important?  

The factory EGR system allows super-heated exhaust gases to re-circulate from the rear of the cylinder head back to the intake manifold. The excessive heat at the rear of the head has been known to be the cause of detonation.

I have personally witnessed malfunctioning EGR valves leak and reduce performance and increase exhaust noise.  I also experience cracked EGR pipe and my “check engine” light came on. 

I drove around for a year with my EGR pipe cracked and its a very common problem with Lexus V8 engine.  After I replaced my EGR pipe the “check engine” light was gone and no more exhaust leak and noise.  However, it was expensive.  Replacing the EGR pipe is very expensive in parts and labor. 

This kit will simply eliminate these problems forever!

The stock gasket can be re-used from the EGR system. Installation instructions and the proper value resistor which prevents MIL/CEL are also included.


The whole package is only $99 (FREE S/H to USA).

This is a freelance site with no support by huge companies.  I have been doing most of the R&D and technical write-ups by myself with my personal money and literally thousands of hours of my time.  I have taken extra steps to demonstrate in details how things are done.  Currently I am one of the few people doing Lexus V8 research and performance enhancement.  This effort comes from my personal love for this wonderful engine.  Most of the modifications are from trial and error. There's no cookbook for 1UZFE mods and its unknown territory for much of supercharger performance.  The parts, labor, web development and site hosting are 100% paid from my personal hobby money.  If you feel my efforts help you in any form, please do not hesitate to donate any amount of money to support this site. You have no idea how much I and the entire Lexus and Toyota community appreciate it!

  1. So how exactly do I buy this kit?? I didn’t see a purchase button. I need to do this on my 94 ls400 so the egr pipe never cracks.

    1. The kits are available. We’ve never once heard of the CEL coming on, only going off. Please see instructions at the top of the page for purchasing. Quantities are limited.
