Just Curious,, My wife recently picked up a new Gs and when you step on it,, it kinda sounds like my old ISF, but just a bit quieter,, just for ****s and giggles,, I wanna put an air intake in the GS and kinda re-live the ISF memories... Kinda miss that car..

The GS has a baffle in the intake that kinda gives it a growl at higher RPMs. I saw a picture of one, but I don't believe the power gain is worth the cost.

Yes I have the K&N CAI on my 4GS. Actually the intake itself is for 3GS but it will fit 4GS also. However you will need to modify the heat sheild a bit. I did this solely because I have this intake sitting at the garage from my previous 3GS.

Joe Z has the intake for it.

@e39ng, Does it sound any different, or have performance/mpg gains?

Thus far, only one intake system has been designed for the fourth-generation GS 350. It is produced by LEMS:

Other intakes on the market were designed for the IS 350 and will not engage all of the intake components:

I also have the intake in my garage, can you posts pics of the mod you had to do please. Also how is the sound? Is it as nice as the sound was on the 3GS?

mrpartsman

$700 for an intake, thats kind of too much, don't u think so.

Outrage

It's expensive. I think it is nice that it's able to be mounted using the stock mounting points, however. Other system I've seen appear to be a bent piece of tubing which relies upon its couplers to support itself.

I think the reason is its made out of titanium.

I know, but what is a horsepower gain on that, there is no facts on it, besides u are not gonna loose the sound factor on it, but Joe Z intake, u loose the sound but u gain 5-6 HP, I rather gain power than noise, and thats when ur exhaust comes in, does it make sense.

Did you get this and if so, does it actually fit? The engine bay picture on their website is not from a 4GS.

This is interesting. So they use the stock air box...which somewhat defeats the puropose of cold air, but they also manage to still allow the "noise creator" to hook up to it. I'd be willing to bet this thing sounds MEAN, but $700 is ridiculous.

Actually I think it is. This thing was designed in Japan, thus right-handed steering wheel, which affects where they put the battery and things.

It sounds great...nice growl once you step hard on the gas. The inlet of the heat shield needs to be enlarged in order to fit the stock ram air pipe(or whatever it called). The heat shield itself does fit quite snugly without any need to screw down.
