you have a weird year...96 camrys are considered gen3.5 as they fall between both 4 and 3
i see no reason why the CAI wouldnt fit your 96 seeing as though they both use MAF (mass air flow) sensors
i wouldnt know personally if they would fit, mostly because im a 4 banger guy, but im sure someone on here has an answer for you...but in any case, it shouldnt be too hard to fit it at all due to the fact that its possible to make one yourself out of some exhuast piping and PVC couplers
springs, there are TONS of options out there....i prefer H&R (even though i do not have them, they would be my first choice if i lowered) mainly because they are 1) German made 2)provide a decent drop of 1.75 in and 3) are pretty performance based check out the camry faq section on these forums to decide for yourself
good luck!
