What's best Intake for FD?
#1
During the install of Rad my factory air box, 1 hose housing was cracked and had to be glued back on. Also saw a dirty air filter, again parts are limited in Canada. Just debating a panel air filter or dual air intake?
What most beneficial and best but out there for the FD?

I do not know the smog requirements where you are, but if legal, I would go for the dual intake and blow off valve. I use the Pettit racing dual cold air intake and a Greddy RS blow off valve. Also recommended is a "Vampire" from J&S in Southern California. You will see an increase in HP.

If you have the stock intercooler, the "Best" intake you can buy is another used stock airbox. It can easily be modify it to source ambient (cold air) from the nose of the car instead of scavenging it from the intercooler duct. Just cut a slot out of the bottom of the box that corresponds to the gap you see beside the upper radiator hose and chassis "frame" rail directly below the box. Then add a K & N drop-in filter and your set. When I had mine, I also used a little silicone to secure some plastic screen over the cut-out which keeps some bugs and debris out and the filter cleaner longer.
There's not much "WOW" factor to it, but there will be NO aftermarket intake system that will perform any better with the stock intercooler for a number of reasons...it shields the intake air from radiant underhood heat, it sources air from outside the engine compartment without additional shielding, it provides both turbos with all the air they need (better/quicker spool up), it obviously accomodates all OEM components and is invisible if you have visual inspections for emissions, it's cheap (you can pick up a good used stock airbox for not much more than the cost of shipping), and you can block off the hole in the top of the stock intercooler duct which forces more air through your intercooler for increased efficiency/lower charge temps.
You will also see very little or no hp increase from changing out things like the BOV.

i agree 100% with Signal... aftermarket intakes really don't do ****. They are pretty... OR, they give you more room for a big I/C.
Also, the stock BOV is way more than sufficient for even a modified FD. The only 2 reasons people use aftermarket ones are for the "wow" factor and because they are easier to fit into an aftermarket turbo set-up than the stock one.

If you turn up the boost zip tie your vacuum hoses to your bov's and where they connect to the manifold. I blew up a set of twins cause the lines popped off the bov's. You can probably reseal your current air box with some good ol' epoxy lol
