I've got the JoeZ w/K&N drop-in filter and I like it so far. Seems to me that I get better throttle response and just a TINY bit more pull at higher RPMs. Btw, I have an IS250.
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.
Where to find the ARC induction box with ARC intake pipe?
I think Lance said they looked like a high school metalshop project or something...
For 1k I'd hope they actually do something, but I can't imagine the gain from it being worth anywhere near the cost (which seems typical of most 2IS mods honestly)
