Hi!!! I've owned my Camry since 1995, it's a 95 (duh!) XLE V6 with the 1MZ-FE 3.0L engine and auto tranny. Well... in the last few months i've noticed some lack of power, it's not a problem, just my foot got a bit heavier

. I wanna know if:
1 - Can I use an CAI from AEM (i think that's the brand) for a 1996 Camry?
2 - Can I use the TRD S/C for the Gen4 Camry? I've read a lot of it, but I still couldn't find anyone who did it and the car remained totally funcional (someone did and couldn't use the air conditioner, and I need mine, 'cause where I live is VERY hot)
3 - Can I fit 235/40R17 tires under my Camry? I have no suspension modifications
4 - Right now I'm running without my catalytic (sp?) converter and without 1 of the two mufflers (the one right behind the cat). Will the TRD muffler give me any performance gain, they claim +3hp, and also some pics of it would be nice, since I can't see the ones on TRD site.
Thanks for helping me, and sorry if I asked too much.
