I just wanted to double make sure...
I have a 2014 isf with all the bolts on plus nos
Currently doing 396 whp base 501 whp nos on
At this time
I have a joe z intake pipe with afe dry filter drop in
Thinking about getting a takeda intake which is open intake with heat shield
Most of review saying it will acutally loose whp due to heat soak n blah blah
So is this really a true ? I really dont get nothing but a sound loud ?

A lot of people have been in the same situation and they all said the best intake you can use is a Joe Z/HPS intake pipe with a drop-in filter, at least in maximum HP applications. It's your choice though. The cone filters look nice but for our cars they don't really do a whole lot performance-wise.

I dunno, the consensus has been that intakes make little or no gains on the dyno but most dyno tests I have seen have been on stock or lighlty modded (I/H/E) ISFs. Maybe the additional power of NOS could cause the stock intake box to be a bottleneck and make an aftermarket intake more worth while?

I personally would stick to your current setup.

FWIW, the K&N did really well in independent testing here (not sure if it was truly "independent"):

while you're spraying the NOS will make the intake cold and you wont get heat soak. If your not spraying you run the risk of heat soak.

I went from stock to the JoeZ to the Takeda. I was the first member here to use the Takeda.

No chance the intake in front of the throttlebody will be the limiting factor even with N2O. The heads are the biggest point in need of improvement after you've put headers on this thing. I'm pretty confident I could get considerably more from a 2UR with some diligent port work and precision valve work. With that done, the next thing is cams to move the powerband around.

Messing w/ internals isn't for the weak at heart though....

most are looking for simple bot ons, but Lobux is hardcore

I ported a 2JZ-GE head for an 8 second drag car. I've built a few championship winning engines. I have a clue about a couple of things.
