HOW OFTEN SHOULD I CHANGE MY SPARK PLUGS. I HAVE A 1998 TOYOTA COROLLA. IS THIS SOMETHING I CAN DO MY SELF?
CHANGING SPARK PLUGS?
if you tinker with cars its easy to do, just do it one plug at a time, and change the plug wire and the dis.cap. if it ha a V-6 the back one on each side may be a little harder to loosen up.
CHANGING SPARK PLUGS?
An annual tune-up is always needed. If you have a V-6 you may want to take it to a shop because the rear plugs can sometimes be difficult without the right tools. With a four-cylinder ANYONE can easily replace them. They are right on top.
Typical change interval is about 30000 miles.
Platinum plugs last much longer, sometimes up to 120000 miles.
Go to ngk.com for a guide to plugs and how to change them as it includes pictures.
yea you can change them if you know how and got the tools. but if it,s running good and easy on gas i think i would just leave it be.
