I've been searching for about a month now and everytime I found a Simota distributor; they never stock it.
Apparently there's not much demand for them, so they don't stock it.
Don't know the price for the carbon fiber one but the HeatShield air filter is $37.28 and the extension kits $41.42, not including shipping.
I did found a distributor in NZ (www.broomfish.co.nz), and apparently they are getting a lot of emails about these SRI kits. BUT they only have SRI kits for the 93-97 Corolla.
I think they have the Heat Shield Air filter and Air Intake Extension Kits, but didn't ask...
Found out that CyberCentury sells the SRI pipe for only $80. I was gonna have a look at it and see if the Simota Heat Shield Air filter and Air Intake Extension Kits will fit it. But haven't had the time.
The searching still continues............
