Damn I change mines at 40k... They were bad.. Plus this truck is driving hard all the time... But 80 k will be best.. If you drive smooth..

 

i changed mine at 60k. they didnt look to bad, prolly could have gone a little longer but i was doing my cam swap so i switched to tr55s at that time. Ill prolly swap them again at the 100k mile mark just for gp

 

Hmm..

My idle quality has suffered here lately and i was thinking it may be time. This truck has beed driven HARD every day since Feb of 07 so i would say that it is time..

Now.. What is the highest mileage NNBS on here.. and what issues have you had..

 

I'm sitting at 95K on mine right now with stock plugs and still runs like a champ. Debating a new truck but if I keep it will be changing plugs and wires soon. I've noticed the MPG drop slightly recently. Other than that, just regular maintenance like oil changes, new tires and front brakes. I've have both clips on the underseat storage and the jump seat storage lid brake on me and thats about it.

By far the best truck I've ever had.

 

102,565miles for me here and on my third trans(warranty)the first trans lost 3rd gear on the freeway and the second had no reverse in cold weather.other than that every thing else is good

 

wtf!!!!on my way home from a friends house today the chime sound came on but no ses light. so i checked the dic and the trans temp was at 208 degrees and lacked some power.the trans fluid is good no leaks and i have all gears,so off to the dealership on monday.i knew i should have knocked on wood after that last post.

 

i change mine every 5k or every time after track passes...

 

X2, most plugs are done by 100k, so change them before they're toast.
