There was a question about ECT switch a while back and I said there is my air intake mod needed to make a big power improvement.
First the air intake, you must remove the front piece of the air filter box.
Then remove the back end of filter box and add a 1/2 rubber bumper to the bottom ( pic)

Now install a K& N filter, use a piece of plastic door edge protector and install it around the K& N

Lexkost

this plastic door protector will take up the room left by the front filter cover that will be left off

Lexkost

now install back in car

Lexkost

because the front of air box cover will be left off you must make to brackets to hold on the over the radiator and use the nuts on radiator support

Now to the ECT reprogram, It is very simple and to be done on freeway ramps...Turn off AC, car must be in 3rd gear ( out of overdive) and turn on ECT make sure that light is on the dash.
From dead start floor it and keep it floored until it runs throught all three gears, and do this about the 6 times , it can be done in a few days and you should notice that the RPM's should start to raise on shifts.........after awhile the trans will shift well into the red line ( only when in ETC mode ) but in regular mode the car will shift much better than before.

The ECT reprogram may work short- term, but being an adaptive transmission, it will eventually "learn" your normal shift patterns and relapse back into its previous shift patterns. I suppose if you are the type that drives aggressively anyway that it will yield long-lasting benefits. I've yet to floor my LS400 and who knows if I ever will!

Yes, but every once in awhile just turn on the ECT and turn off AC and put in 3rd and punch it getting on the freeway ............Mine has been working for 4years with out resetting to the factory default.

Maybe this is not for you.

my main concern with the intake is that its drawing in hot air from the rest of the engine compartment.

what makes this better than the infamous JBrady BFI?

Lexkost

Only while car is stopped, once the car is moving it gets more cool air than it can take in,and also extra cool air keeps entire engine compartment cooler.

I don't like how loud the car becomes without the intake cover, although at times it sounds good too.

So what kind of performance gains can one expect? Is it noticeable? Where do you notice the increase? Low, Mid or Top?

I have to admit that is a very creative way to improve the stock intake.

Lexkost

Every other year I put it back stock to do smog and the difference is unreal ! !

Where do you notice the increase in power? I would hope it would improve the bottom end and midrange. Top end on these cars are good.
