Be careful buying intakes for an 06GS300, that's what I have and the GS300 and GS350 intakes are different. Since the 2006 engine was only made for a year there aren't a lot of options. There use to be a few out there but DC is the only company that still makes a cold air intake for an 06. At this point K&N's cold air intake is rare because they stopped making it for the 06 a long time ago. Fujita is rare but I doubt you will find one. Even if you do be careful because the early models caused error codes. Scratch joez off your list because that will not fit a 300. The following site may have some rare parts but I think everything on there site is overpriced.

I'm going to have to consider what to do with it now....
They make a ton of F Sport stuff for the 350.

I don't know for sure either way but i doubt it. There aren't any F-Sport intake products that work for an 06 to my knowledge. I ordered the F-Sport air filter from my Lexus dealer but it didn't fit my 06. It came up as the right part because I guess there are some 06 350's out there.

I don't know too much about the 3gs but I do know enough to get me around. just make sure when you order parts that it will fit. I haven't seen much parts for the 06 3gs and never could figure out way

just IMO, if I can't fully fabricate the part I want, ill buy a similar part with close measurements and just mod it to where it will work and fit properly.

Hey guys,
Im here a whole 11 years later… wondering how i can even get 15 more hp to my 2011 gs350. And after EXTENSIVE research i’ve found that it’s probably impossible. But if anyone’s found anything in modded the 2007-2011 gs350 engine please reply!

Probably only an intake and less restrictive exhaust, especially the secondary cats and mufflers. Still wouldn't add much hp though.

Impossible? lmao not even close. If you wanted to gain 50hp you could. There are plenty of bolt on mods and tunes available that your GS350 could make over 350bhp if you wanted to. don't listen to these uninformed idiots.

It's actually pretty easy, in fact there are quite a few 350s making more than 300whp.

So why are you lying?

It's almost as if I haven't seen everything, hence the 'probably'.

TreysGS460 exit this thread.

It's really easy to disagree with others without insulting them. Expect you to do that going forward or do not post.

Just put him on your ignore list. I did this last fall and it made my forum experience vastly better.
