Upgrading My IS300
I have a IS300 2001. Just has a K&N filter... 
I'm planning to buy these week a Header. what else I could install to improve the power.
NO Turbo, No NOS.... Just all motor!!!
Someone recomended to make a Valve Body Upgrade! What u guys think?

if you do both cold air intake and headers I suggest getting a heat shield too, you can get them from lots of places but I personally support FIGS, if you dont know about FIGS just google FIGS engineering, lots of good stuff including hood props to get rid of the stick to hold up the hood, point is that heat soak could be an issue depending on how you run your car, the heat shield sits above the headers and below the intake creating a buffer zone for heat
intake: i went with K&N, i love K&N and I use them in our RX 300 as well so its not only a brand loyalty thing but alsot they test them to make sure you get good performance without causing a check engine light
headers: go for long runners, I went with the OBX short runners and honestly....i dont really care for them, sometimes i almost feel like its worse with those than stock, megan makes some long runners i believe
valve body upgrade: i have not done this myself but from what i understand is you send your off to toyomoto (i think thats who does it) and they modify and and send one back to you. as far as i know this doesnt create any additional power but instead reduces your shift times but im pretty sure this requires you to add a transmission cooler
the information about the valve body im a little sketchy on as i have not done it myself and it has been well over a year since i did the research on it but im sure others can chime in and fix any mistakes i posted
hope this helps
for intakes i would go SRT intake hands down. their intakes with the piggy back black box produces the most HPs. the other option would be an intake but with with an Apexi SAFC
for headers i've seen Mazzuri or someting produce some good numbers. if youre going to swap out the header you might as well swap out the Y pipe and exhaust too, HKS Hyper. doing these headers plus exhaust produce the HP numbers but get ready for LOUD car.
valve body is probably over kill
toyomoto? lol. theyre out of business
if youre considering valve body upgrade talk to SRT or Peter Farrell Supercars

headers and a cold air intake are good places to start, heres some thing to know first though

FYI outside of the honda world the term all motor isnt used. generally people call it NA or Naturally Aspirated

i didnt think you could get new mazzuris anymore, and it shows how long its been since ive done my research if toyomoto is out of business lol
baadhabit is right about the SRT intake though, from everything ive read in the last 2 years since ive bought the car that particular thing seems dollar for dollar the best upgrade for this car, i will probably go with them eventually myself but ive got my money tied up in my networking business i started back in october...

i think what hes referring to is all motor as in theres not alot to be had with bolt ons with 2jzge(others are way better about adding power with bolt ones like Honda) ...I know cause I'm one of the crazes when i was NA i had everything done other then HC pistons .....
