plugs are easy. Posted by JimBlake [Email] ![]() ![]() ![]() In Reply to: Re: ps: how old are your spark plugs? (nm), StefM, Wed, 27 Oct 2004 11:07:17 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Get new spark plugs, since you don't know how old they are. What the old ones look like says a lot about the engine's health. Plus, you can look for any evidence of burning or arcing on the DI cassette.
If you don't like to mess with them often, or if you pay a mechanic, then get platinum plugs (NGK PFR6H-10). About $12 each, every 30k miles.
If you don't mind changing them every 10k or 15k miles, copper plugs are only about $2 each. NGK BCPR6ES, gapped to 0.035" or 0.037" or so. Maybe they'll last longer, but base that on your own experience, not other people's.
Check the link below for how to remove the DI cassette, the plugs are beneath it. Don't overtighten the new plugs. Get NGK, don't get a different brand.
