coolant bleed ?

To prevent any damage to the engine, yes, of course it is necessary.
Open your radiator cap and start your engine.
Let it warm up in idle (needle at normal op-temp).
Open up the heater core by turning the heater on in the car on full temp and full fan.
You will see the coolant level drop, now squeeze the big upper hoses until you see all the air bubbles escape.
Top off coolant and overflow bottle. Enjoy

According to the shop manual, the car is considered 'warmed up' after the radiator fan cycles twice.

Yep Darrin installed it last night. I squeezed the hose as the engine was running, but I was afraid that the coolant would overflow too much, and I didnt have someone to sit in the car and turn it off quickly if it needed to be. I'll finish it off tommorow morning.
Install was pretty straightforward, but the stupid plastic clips in the fenderwell were the biggest PITA. It didnt help there was a thick layer of road salt covering everything.
I couldnt really tell a difference in hp, and it sounds I would say 95% the same as stock. I'm gonna dyno it within a week or two and see if I gained anything. If not I'll just sell it, and put the $$ towards some new tires. I'm sure it takes a little time for the computer to adjust, so I'm holding my judgement on it till i dyno it.

Niteqwill has anyone that has NOT done the bleed had any adverse affects from it? Just curious, since I cant ever recall reading about anyone having cooling problems.

i installed it without bleeding it and the engine temp meter would go up and show an over heat while idoling for a long period of time, it wasn't actually over heating, it was causing a false read.

I've had my CAI installed for 4 years, never bled the radiator and never had any problems. I do have my radiator flushed every 2 years though

If you have a air pocket in a coolant line as it travels around the cylinder head, you can be asking for trouble.
