After 6-1/2 years, my 05 LSJ is coming up on 150,000 miles.

since i picked up the car in july 05 w/ 14 miles, the only engine related maintenance that i've had to do included:
crank position sensor replacement at 5k
vacuum pot at 35k
spark plugs at 75 and 135k
transmission fluid at 100k
supercharger oil at 100k
stage 2 at 100k (if i was going to replace the serpentine belt anyway...)
and the normal oil/air filter changes.

i know i'm due for a change of the coolant last summer - i think i remember reading that 150k is probably a good time to change out the water pump, too. any other recommendations?

 

intercooler pump

 

tires?

 

What spark plugs are you using to go that long in between?

 

that is recommended for cars that have timing belts your pump is good
