Okay so i just bought a 2000 model honda civic it is the vtec d16y8 motor and it has 200 thousand miles on it i got the car for 2900 so i thought it was a good deal with everything working and the car looking great running and sounding great it is a sharp looking car i was just wondering with it having 200000 miles on it is there anything i should do ??? He said the motor has never had a rebuild that it is all original all stock i was just wanting to know is there anything i can do for it to make sure it last another 50000 miles smoothly i was thinking about getting a cold air intake to help the engine life it is all stock just let me know any ideas i am also wanting to mod cusomize it maybe give it a little more power and looks like i said its all stock so any ideas ?? i have a grand to spend on it
