I was just wondering if the injen CAI from a 1995-1996 240sx will fit on a 1991 240sx??

 

pretty sure it wont

 

Actually, it should. the only thing is you might have to make a custom mounting bracket for it. I have an AEM short ram on mine, and the mounting tab didn't line up, so I used a zip tie to hold it in place, and it works good. I don't know about the cold air extension tho.....

 

The short ram air intake from Injen might line up the same way but the extension in no way shape or form will fit.

 

not without mods.

 

I've heard the TB connection wont fit right.

 

I put a short ram from injen for a 95-96 into my 93, just a little reworking and moving, but it was quiet easy

 

The Injen extension for an S14 will work. You will have to cut the extension down a bit and maybe shave a bit off the MAF adapter. I installed a no-name short ram intake with the Injen extension on my S13 hatch and it fit fine after a little adjustment.
