A turbo timer or cold air intake are a waste of money!
When you look under the hood you can see that there are coolant lines running to the turbo so its oil and water cooled. No need to wait there and sit for it to take a cool down lap.
Also many reviews and dyno tests have shown that intakes give you very minimal gains on the STi, I'd just take out the resonator and call it a day. I took mine out a couple of months ago and felt no power difference whatsoever but the sound you hear now when in boost and when its releasing pressure through the bypass valve is nice.
With the mods you already have I'd consider a header/up-pipe combo like GT spec makes.
Or if you crave even more power replace the Cobb AP with Turbo XS's UTEC. People on other boards have posted dyno charts with hp figures of over 300whp with just the UTEC and a turbo back.
