Mazda 3i or 3s, how can I tell what i have?

pop the hood
it should say right on it whether its 2 or 2.3L

Mine does at least :)
Goodluck
 
The Mazda 3 s.=It has 17 inch wheels, not hubcaps or small wheels. It says 2.3 on the side of the car near the front. The rear tail lights are gray, not red.

Open the hood and look at the top of the engine. It should say 2.3 on large silver letters if it is a 2.3 S model.
