ARC induction box with ARC intake suction pipe. that will give results, but will cost a pretty penny. out of all of them though available i would go Joez or K&N. joez is proven and it reserves the cold air snorkel and the box is what keeps the low end. also K&N because of the heat shield and it also incooperates the snorkel. also if you try and seel the top cover panel you create almost a virtual air box like Javy did.

^^^ How does the K&N incorporate the snorkel? The heat sheild is not sealed, so it isn't going to suck air through the snorkel, and the snorkel isn't a ram air scoop, so I doubt there will be any cool air flowing through the snorkel at all. It's like trying to use a straw to drink without sealing your lips around it.

basically the K&N and their design is second best compared to the JoeZ. want sound and little gain go with K&N, want the same mount of gain and keep that ittle bit of low end power then get the JoeZ. if u got the moola go ARC.

I installed my Fujita Today. took approx 35 Min to install.. tools needed was philips and flathead, and a few sockets.
i removed the covers from the stock car, and the sensor from the air box. ( < 3 min)
screwed sensor onto pipe. (1 min) removed entire stock tubing from car. (5-8 Min)
fujita fits right in. easy screw ins (10 min)
filter goes right in, as well as all covers co back on. (10 min) i had to cut a small peice off the cover so i can snap it all together. (3min)
i forgot to take pix during installation, but ill post some pix up and link to it later.
the fujita F5, about $200, i have not dynoed but you can definately hear it around 3000+ rpm. i do feel an increase in hp, and on the freeway acceleration, when the car hits 4000- 4500RPM, u can DEFINATELY hear it and i have to say, if u can always drive around 4-4500rpm, the car will soud like a V8.
this is just my $0.02.
btw, i have a 06 IS350.
again, will post links up to pictures of finished install.

From http://store.my.is/store/customer/pr...&cat=47&page=1
regarding the JoeZ intake for Is250 and 350
Independent DYNO Test results on a stock IS350 have shown gains of 5+ Rwhp Max Power & 5+ ft.lbs of Peak Torque.
The stock manual 6 speed IS250 showed gains of 6+ Rwhp Max Power & 5.6+ ft.lbs of Peak Torque.
DYNO Jet Graphs are SAE Corrected
IS 350 Black
6 Speed Auto - 4,959 miles
THIS IS THE SAME IS350 WE USED IN THE FIRST DYNO TESTING DONE ON 3/9/2006
Base Run
Max Power 265.8 Max Torque 241.7
w/ Joe Z Intake Pipe Installed
Max Power 269.7 Max Torque 245.4
Gains
Max Power = 4 RWHP* (rear wheel horse power)
Max Torque = 3.7
Measurement of percentage of Factory Rated Base HP (306) to Dyno Tested Base RWHP (265) was an approx. 14% loss to the wheels.
Here is a link to their dyno sheets

Its that the Dyno tests and company say they gain...

It isn't that some people gain, and some loose. It's that some people believe they gain, while others know they loose.

Let's have them repeat the tests with hood down, no fans blowing, and actually moving down the road. Dyno tests are not real world conditions, and 4 hp is a TINY change. I've seen a 10 hp variation across three runs in 10 minutes with NO changes at all, so I'm extremely skeptical of these kinds of results.

And yes you can still re-use the engine cover. FWIW, I currently have the FJ Cruiser version & love it. TRD sells the exact same version (albeit w/a slight airbox mod).
