precat

i own an 05 spec all stock except for aem short ram. it also has the Nissan certified rebuilt engine which i believe has about 75000 miles on it? who knows. in total, i just rolled over 131000 today, and besides replacing a camshaft sensor, everything is pretty much smooth. but....it still has...
