EDIT: I need to make a correction i’m actually installing whats call a WAI or Warm Air Intake not a CAI (Cold Air Intake). there is a difference and let me try to explain:

Cold air intakes will produce more power, and will save gas if the engine operates only at Wide Open Throttle.

However, under 90% of driving, Warm Air Intakes are more efficient because the engine is throttled and under less than full load.

WAI does two things:

1) Fuel evaporates more quickly, increasing combustion speed. Fast burn engines improves the amount of pressure generated and expansion work available for a given amount of fuel.

2) With oxygen sensors, engines run at stoichiometric air/fuel ratios. For any given amount of fuel, a corresponding mass of oxygen is admitted. WAI lowers the density of air, meaning that a higher volume of air must be let into the engine for a given fuel input. So with WAI, the throttle must be opened further for a given output, and this lowers the “pumping” work of pulling air past the throttle.

as you can see above thats my engine compartment of my car. its very boring i know. well i have started to piece my WAI together. however i ran into a small problem my 90 degree elbow i have is too big. so i dont have enough clearance for my hood to close. i have to find some smaller elbows.

but not all is lost i was able to at least replace the air filter!
