OK so i bought a 2004 cav about 2 months ago and i am confused on a couple things. I have the ls sport bumber kits and fog lights and a sunroof but no power locks or windows and i dont have the chrome wheels jsut he plain alloy wheels how do i know if its the ls sport version or not? and i was told if i jsut have a 2.2l not the ecotec i cant put a cold air intake on it? is that true? and how do i know wat i have?

all cavaliers an sunfire from 2003+ only had one motor and that was the ecotec motor. as for your ls kitted cavalier. it may have been a base cavalier with the ls sport bumpers put on.

btu i have the rear spoiler to.....how can i tell? and really wats the difference between the base model and ls sport model?

i had the ls sport suspsension.. rims and spoiler on my base..
the spoiler is also used on some base model an regular ls cavalier non ls sport

so how can i tell wat i have exactly?

run a car fax report with your vin..
