Just wanted peoples opinions on replacing the spark plugs for a 2003 Honda Accord EX-L I4. The car is almost 7 years old. Was wondering if anyone out there thinks it would be worth it or wise to replace the spark plugs? Fuel economy has dropped but the car only has 83,000 kms on it. I've heard the NGK plugs last until 160,000 kms. Thoughts? or is replacing plugs a waste of time?

Fuel economy has dropped but the car only has 83,000 kms on it. I've heard the NGK plugs last until 160,000 kms. Thoughts? or is replacing plugs a waste of time? Spark plugs start degrading the first time they are used. Contemporary plugs use much stronger materials for the electrode and the tip that can conduct much better. They are also designed to withstand the hotter engine temps. The vehicle electronics are sophisticated enough to compensate for wear patterns on the plugs, and can "reverse fire" to help keep them clean. All this said, for the $15 and 30 minutes to change your plugs, I wouldn't hesitate to change them. I don't know that you will feel an increase in power or not, but the car will run better/be happier and have to compensate less for electronics. I would replace them with the exact same plug.

Replying to: blufz1 (Oct 04, 2009 8:04 am) I'm pretty sure the original plugs are Iridium tipped. The platinum plugs have the same part #, but are not "long life" 100k mile plugs. If I was going to replace the original iridiums with platinum, I would not do it until 100k miles.

The information display above the vents/Nav screen on my 2003 EX-L NAV has gone out. It will come back on if you press down on it or give it a good whack but only briefly. This problem has come on gradually but it is almost always out now. Has anyone else had this problem? What is required to fix it - a bulb? it is almost acting like a loose wire. Thanks in advance. |
