Thanks Kurtz.

So no intake gives over 5hp? I just want to add the most HP available since there is not much available in the HP TQ dept, i thought i would maximize everything. Isnt the Joe Z just a pipe? I just took my smog test so I could always swap on the stock intake in 2 years.

 

Yup... apart from marketing hype I've yet to see any available 2IS intake reliably dyno over about 5 hp... (there's supposedly one designed by another forum member that will do a little better, but it's not for sale at this point- might be in the future).... and you're right, the Joe Z is pretty easy to swap back to stock, so if you're comfortable doing that (and it takes maybe 5-10 minutes if you're comfortable working under the hood) then you can always just switching it out for inspection after 2 years then switch back, and still save the $.

the only thing 'extra' besides a reusable filter the F-sport gets you are:
The 'This is legal in CA" certification
and
A replacement lower airbox with an extra hole- this is just to add some noise, and you can cut your own stock airbox with the same hole for free with a dremel or something if you want the noise

 

^^Sounds good thanks for your help.

After almost a 10 year hiatus from the lexus world, i was shocked and confused at first when i came back to CL with all the hella stuff and seeing leaning tower of pisa wheels and tires that dont fit. Glad there is some resemblence to the old days. Thanks again.

 

You could always go to the parts counter and buy a CARB approved intake sticker for $5 like I did!
