are there any cai or sri that will fit on the 2.3 with this turbo kit installed? all the pics show it the the stock air box..

 

There are quite a few. Injen, AEM, etc. Just google Mazda 3 intake. This will help increase airflow to spin those blades faster from the exhaust gasses. The stock airbox is quite restrictive if you've ever removed all those plastic pieces from the engine, especially on the drivers side - the air intake goes to the battery!!!
