No — this part has no CARB Executive Order, so it is not for sale or use in California or on vehicles registered there.
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.

The core and end tanks, plus the couplers and clamps the kit calls for; some kits include new piping. Check What's in the box.
Kits are built to fit the listed cars. Some need the bumper trimmed or the crash bar moved, and the maker's guide says so.
An air-to-air intercooler needs no fluids. Water-to-air kits reuse or add a coolant loop.
A larger core and better end-tank design keep the intake air cooler under sustained load, so the engine makes steady power on a hot day or on track.
