I finally got my intake! Just installed it a few hours ago. To be honest, I'm not sure I can tell much difference beyond a little more growl when the RPMs swing past the 3600 mark. However, the intake looks very nice and the fit was spot on.
Do those of you that already have the intake swap the OEM back in before you take your car in for service?

You should try sourcing your own piece of aluminum, getting the degrees of bend and diameter just right, welding the two outlets at precisely the right place and angle (which is not an easy 90 degree bend), and then anodizing them. Oh, and don't forget to include the airbox and throttle body sleeves and clamps (which isn't nearly as easy as it sounds). And make sure it looks nice and smooth, too. Price that out and see what it costs you to make ONE before you post about something you've obviously never done before.

That Raw stock will set you back about $28 or so. Then you need to Mandrel bend it. If you crush it you'll lose flow. And then you'll need to drill and do 2 MIG welds (Tig is not needed as its not as critical point). Or if you're really skilled do 2 counter sunk holes. Then Hone the edge and do a locking washer on the top (same way hard lines are used on an aircraft.) But even then without the proper tooling one is well over into the 100 zone.
Even with a rough break down:
28 =Raw stock
+25 (bend piping)
+20 (for upper 6061 piping)
+30 (for 2 mini welds) (if one is to weld)
+40 (at least) for Anodizing (if you send it out)
And time is money....Kudos for the true Macgyver's...
The money spent on buying the premade is worth it

I service my car at Sewell in Fort Worth. I'm hoping since Sewell seems more mod friendly it won't be an issue.

Peak power hasn't really changed, but I'm short for words about two sections of the power band. 3200 to 4100rpm and 5100 to 6100rpm the stock intake has considerable more power which I can't explain. (intake resonance? timing?) The JoeZ pipe made more top end power from 6100rpm to redline.

Hey James.. Great Dyno runs..
It might be a good idea to re-verify the base numbers..
I can't see the graph to well either way..
^^ Not necessarily..
Gains are indeed approx 5rwhp.. Results can very from car to car or dyno to dyno..
So far to date, 3 other IS-F's were independently tested & achieved the approx. 5rwhp gain.
Thank you
