Can + I = Cay. When you ask someone a question, you say Cay instead of "can i".

Lovely, sweet and handsome boy. Has eyes that look like the waves, crashing against the calm sand.

A super cool boyfriend, it is hard to not be in love with him. He is the kind of guy, you want to take home to your parents, and eventually marry and have a family together.
Cai is a loving person who will do anything for anyone, even if they have done wrong to him. If you ever lose Cai, you will be sure to regret it.
'Cai is such a cool guy.'
'That's Cai for you'

Cold Air Intake:

Cold Air Intake Systems let your engine breathe in large amounts of cooler air, resulting in increased power at the wheels. Cold air intakes enhance the combustion process of your engine, which uses both oxygen and fuel. Cold air intake systems pull in more cold air, more cold air means more oxygen resulting in more usable power and torque throughout the engine's RPM range. Most Cold Air Intake systems relocate the air filter outside of the engine compartment or away from the heat of the engine for a cooler intake charge. Cold air is denser and heavier than warm air, which means that there is more oxygen in a cold cubic foot of air delivering a higher volume of air into the engine. Replacing your vehicle's stock air box with a cold air induction system removes one of the biggest restrictions on your engine.
