I am thinking about changing the spark plugs. They have never been changed and the car has about 200,000 miles on it. The engine runs good though and it gets good gas mileage. It was my parents car. Is it worth it after all? I looked at a video on you tube real quick and it looks like it would take a while. What plugs is everyone running, or what plugs work the best?

It'd prolly behoove you to replace the plugs if they've been the same for 200k miles. It's pretty easy to change 'em out, just make sure you have the right spark plug socket and a socket extension. You'll also need a 10mm socket to remove the acorn nuts holding down the ignition coils. If you don't have a torque wrench, don't crank 'em in, since they only need to be torqued to like.. 13.7 ft-lbs. If you don't have a torque wrench, screw them in finger tight, then an additional 1/2 turn or so.

On my 2002, I ran Denso iridium IK20s, then later switched to NGK IX iridium 6441 plugs (part number ZFR6FIX-11). The OEM Honda ones are NGK laser platinum 3271's (part number PZFR6F-11). Can't really go wrong with any of them, and should really only take you maybe an hour if you're taking your time to make sure you're doing it right. If you want practice to know how you're doing, pull the old plugs. You can always post a pic here so we can tell you if they look good. Wouldn't hurt to grab a spark plug gap tool to make sure they're properly gapped from the factory. They're like $3 at the counter of any car parts store. Should be gapped to .044" from the factory. If you get iridium spark plugs, just be careful bc those electrodes are pretty fragile.
