Hello, I've been doing alot of reading on simple cheap mods I can do to my LS 400. I have read about the Jbrady and Lexkost air box mod and curious if anyone is running either and pleased with them? I read how everyone loves the sound but other than that is there a benefit? I bought a K&N filter when I first purchased the car. Would I be better off just sticking with that? Thanks

I'm running the Lexkost intake on mine and have been for several years with a K&N intake. Definite increase in audibility, but to my knowledge, nobody has run either mod through a dyno to compare before/after results. Some owners report a seat-of-the-pants increase, but any gains I would estimate to be very small.
If you decide to do one or the other, the Lexkost mod takes all of five minutes to complete, and if you don't like it, you can just put everything back the way it was - no damage done.

There will be almost no benefit at all just modding the air box.
Intensive tests and experiments were done as well as the strict simulations at the design stage. In order to get better results, you would need to do more work than those.

I got my rubber door trim at an O'Reilley's for less than $5; not running a (rubber) bumper; it's very secure without it.
