Here's the video I took....sorry for crappy quality.

 

The video doesn't do that intake justice. I tried to take a video like that when I had it on my 3GS and the sound just doesn't come through like it does when you're sitting in the car. This is one mod I will attempt again, once K&N finishes their R&D...mainly because I left that intake on my 3GS when I traded it in, so if I'm buying another one, I'll wait till they have one specifically for the 4GS.

 

Very true...It did not capture everything. It is actually much louder.

 

I wanna hear some down shift in that video, and 1 question is it hella louder then the sound creator?

 

Yes it is noticeably louder than stock.

 

Beautiful sound!

 

Update please, how is your intake doing is it holding up fine? Did ou feel power loss at all i ordered mine and dont want to feel that i have wasted my money if its not good.

 

Nice, just sold my 2006 gs300 and now I have a liquid platinum GS350.
now I want to install an intake too.

 

We have a sound creator? is that the extra pipe on the side of intake ? under engine cover?

 

I have the joe z intake tube with k&n filter and sounds real nice. Not to loud either

 

Yup. That extra pipe is responsible for that growl you hear in the upper rpm range.

 

Has anyone tried the 3GS F-Sport intake on the 4GS?

 

Thats what this thread is about. He used a 3 rd gen intake on a 4th gen GS. The f sport intake should fit If he used a reg intake on a 4 th gen GS.

 

My bad, my post was too vague.

I meant more if people encountered similar issues or problems with the heat shield from Lexus as oppposed to the one from K&N and such

 

I am considering removing the 4th gen sound generator (non-F-Sport) and replacing it with a 3rd Gen intake. Prefer something more quiet. So does the 3rdGen non-F-sport work on the 4th-Gen non-Fsport? and does it impact the warranty in any way?
