I posted this over at the ST org site but figured I would also put it here.. I think this is the best bang for your buck on a ST intake while keeping it as close to OEM Ford as possible.

Air intakes

Everything you need:

RS OEM upper intake tube (Tasca) Part Number: G1FZ-9C623-A $69.50
RS OEM lower intake tube (Tasca) Part Number: G1FZ-9C623-B $51.03
Silicone 3" to 2.5" coupler/reducer 3" length* ~$6 Ebay
45 Degree Racing Silicone Hose from Ebay (intake side - optional)** $10.95

* Or use 2.65" length piece of scrap 2.5" OD tube (muffler shop, etc)
** Or Mountune high flow induction hose $69 or reuse the OEM stock accordion style elbow

If it's for a titanium then u want the complete RS box since it gets rid of the hole & resonator junk underneath. The RS & ST lower portion of the box do not have the NVH resonator crap that is on all the basic n/a focii so he would want to replace the entire box and also delete the nvh snorkel and add a ST inlet. If you read the snorkel delete & new mission mod thread it will explain the resonator hole & snorkel.

Has anyone noticed an increase in performance or louder turbo sounds from this mod? Or is it more for looks?
yes you will lay a rubber patch to freedom with this mod!
