Nice! I recently got my first Taco (had a tundra before, loved it). It's also a 95 XtraCab 4x4 SR5
I'm also looking to get 5100's all the way around, but not 100% sure yet, and springs. I just put the K&N air intake on. When I installed on my tundra with the 4.7, it literally made it roar. I was expecting similar results on the 3.4 but didn't really happen. Changed the sound a little bit, but not much. I could definately feel a slight difference in performance. I haven't checked fuel economy yet, though. This is going to be my off-roading "toy" when is all said and done. I have an 08 F250 and a 12 E350 for daily driving/towing, so i'm really looking forward to having some fun with the taco. Planning on upgrading shocks, springs, leaf packs, UCAs, wheels, and going to a 33" tire once I get 3" of lift ironed out. Are you planning to lift yours (or is it already lifted?)? Is it a manual or auto? Good luck!
