I have looked up various parts and just recently ordered a CAI for my mazda 3 sedan.. it goes for the mazda speed 3 and from the look of the picture and the descripiton looks like it can fit my sedan..(note it dose say it fits sedans) but my point is that the mazda 3 hatchback's engine compartment looks just like the sedans.. as well as the interior.. is the only difference in the rear and how the exhaust system is set up ? ( the sedan has a "channel" under the car that the exhaust runs under).

What im tryin to get at is can the sedan use all of the same modifications at the hatchback model ??

 

I would say yes to the intake. But the Ex system will likely be different.

 

well i know the exhaust will fit, but im not sure about the speed3 CAI if anything the reg hatchback 3 components will also fit the sedan.

i have a mazda 3 sedan 2.3 and i have had the speed 3 intake in my car for at least a year now and its great..it def fits and with the exhaust i put on my car it works pretty well

 

Me tinks yuz guyz are confusing the Speed3, with the Mazdaspeed accessory parts.
I really don't think you can put a Speed3 intake on an NA car w/o a lot of problems (e.g. a CEL at least.) But you could put the Mazdaspeed CAI on it, which is built by AEM and designed to work on the NA cars. Like this one... mine.



BTW: The sedan is 1.68" longer than the HB, so if you install an exhaust designed for the hatch, you may have to extend it a little so as not to melt/burn the rear bumper.
