It is diffenetly worth the money for all those parts epk.When you bro passes on the LS to you these should be one of the mods that is a must.

I believe Jbrady said that it increases the hp thru out the enitre power band if i could recall.

i agree... an intake and ecu would be one of the better upgrades, no matter what gen lexus u have. I wish someone would come up with more aftermarket parts for the LS, because trying to find things like exhausts struts, STBs etc away from Lsportline is driving me nuts.
Funny thing is , Lsportline doesnt even have products for the LS in production until later this year

You guys we are the few diamonds in the ruff.Not to many would mod up a LS,but modding up LS has it's uniqueness to it that is why i leaned towards a LS than a GS.

I just see to many GS's out there that have mods,even though it is my favortie lexus,but a LS has its own flair and style once it is all dressed up.

Generally, increasing air flow capacity only helps at higher RPM because at low engine speeds the air requirments are lower and the lower capacity parts are not a restriction. In fact the stock parts aren't too bad. SRT does a number of things right that contribute to an accross the board power increase. The parts flow better than stock, they create a high pressure area at the throttle body (effectively making it bigger), they maintain cold air (outside vs. inside engine compartment) to the air cleaner and they tweak the air/fuel/timing for an additional boost.
