For those that do not know me I have been a hi performance nut since 1972 when I got my first go-kart and started learning about and then making performance improvements. Since that time I have been involved in many projects including turbocharging and supercharging 1500hp engines.

Now, the goal with my Lexus was an improvement in performance in a package that is easily returned to stock for warranty purposes. I had looked hard at the intake design on my 1996 LS400 and now my 1999 LS400. I also gathered great data from "Petes Soarer Page" (SC300s and SC400s) at http://www.users.bigpond.com/pgscott/BFIDIY.html Please review the details for the specifics of some of my reasoning on this mod.

Now, the mod is "stealthy" in that it is not immediately noticeable upon inspection. This is due to my use of the factory parts wherever possible. This decreases cost significantly and keeps lots of quality Toyota/Lexus engineering. (again review above site for specifics) So far I have increased the instant available air to the air filter by well over 200%. Seat of the pants (SOTP) feels faster and the engine sounds GREAT! Doing a similar mod on a 250hp SC400 yielded 17 horsepower! Again, review the site.

If I decide I can build a kit to sell I will let everyone know to judge interest level. This kit will fit 1995-2000 LS400s. 90s-94s should work similar but I will have to look at those models. Anyone in Houston with a 90-94 LS400 that is interested... let me know and I will take a good look at your car. Also, anyone that has a air filter housing that they do not want/need from ANY LS400... let me know. I would also be glad to look at an LS430.
