Hey 4BYFOR do you know if any of thoes mods will void the factory warrantyMy opinion,
1- Performance air filter or pod and snorkel for cold air intake.
2- Exhaust system ( preferably turbo back with dump pipe ).
3- intercooler upgrade with hard piping.
4- tunable chip like unichip, steinubar or chip it..
Mate you would really need to contact your dealer and ask that question.. I had 1 service at nissan and never again, I do my own services and have a good mate that's a mechanic and he helps me when I can't do some things.. Stamped all my books just incase engine blew up but it's out of warranty now so all good..
