2001 Toyota Corolla 4 cyl Front Wheel Drive Manual 196000 miles
Last time I purchased and installed my spark plugs was about 63000 miles ago.
How often should I change these spark plugs?
And if I buy those 100000 mile plugs will they last for 100000 miles?
I cummute about 170 miles a day 5 days a week.
yes it's about time to change those plugs, and don't forget the air & fuel filters as well. Long life Iridium spark plugs will go the distance they are a good investment, I try and use them in lots of customers cars my self.
