Intake...
Try looking here for opinions on them: https://www.clublexus.com/forums/performance-251/
In fact changing the intake tube would just remove the sound generator and would free up some flow.
I think it was doing a drop in filter F-Sport or K&N was more beneficial than doing a short ram cone filter type. Seeing as NA engines don't respond to intake mods as well as forced induction cars do.
Short ram cone filters just make a different kind of noise, which some people like.
I personally just put in the F-Sport filter and called it good, I felt the car run better, but I was probably also due to replace the old filter.
There's alot of opinions out there and disccusions in the performance section, but I felt a drop in filter is good enough for the 350/250. I dont know anything about the 200t though.
I think intake tube options were:
2IS FSport tube
3IS FSport tube
JoeZ
RR Racing
Drop in filters:
K&N
F-Sport
Tom's
Cone Short Ram:
Injen
Takeda

I bought an F-Sport air filter and airbox lid back in September, and my feedback is that the filter makes zero lick of a difference in performance improvement, so I wasted $360 CAD, but I do like OEM stuff, so I'm stuck with them. I don't recommend the F-Sport intake unless you like the look.

Earlier during the summer, I had conducted some research on the effect of MAF g/s with different intake systems (using a JoeZ intake pipe and a 3IS F-Sport intake pipe). After several weeks of switching back and forth between intake pipes and documenting data using similar temperature differences, I found that both pipes exhibited similar peak/max MAF g/s figures (around 245~246 g/s). However, I did note that in terms of consistency, the JoeZ pipe was consistently performing at or near its peak MAF g/s rating during each WOT pull whereas the 3IS F-Sport intake MAF g/s varied quite a bit (my assumption is that the sound creator/generator has a small impact on the consistency of the air flow from the intake pipe to the throttle body). Here are a few of my datalogs below:
3IS F-Sport Intake Pipe:
JoeZ Intake Pipe:
A replacement pipe can/will usually remove the sound generator which can further improve flow and reduce turbulence.
I would suggest the F Sport Intake System, or just replacing the filter with a Re-Usable, Higher Filtration, Higher Flow unit such as:
- Lexus F Sport
- TOM'S Super Ram2
- HKS Super Hybrid Filter
- BMC Air Filters

What Im confused about though, were that some of the forum members saw power loss with the JoeZ intake. I can only speculate why that happened.
Right now, Im considering either the FSport Intake pipe (without the sound generator) or the K&N Typhoon intake pipe. I dont mind the loss of noise generation since I get plenty with my exhaust already.
Which option would be more worthwhile @redspencer ? My gut tells me that itd be a negligible difference between the two.

Regarding the JoeZ intake pipe, the piping diameter is slightly smaller than the 3IS350 F-Sport intake pipe (2.75" vs 3.00") though the data I've collected doesn't show one or the other achieving a higher MAF g/s. On my build thread, you'll find multiple posts that I made with additional datalog comparisons that I made between the two pipes (beginning on post #442): https://www.clublexus.com/forums/bui...l#post10284420
