January 25, 200521 yr I just bought 4 new NGK v-power spark plugs for my 92 loyale. Do I need to set the gap? If so, how do I do that. Do I just bend it and measure it? Why am I an idiot?
January 25, 200521 yr some are pregapped. feeler gauge should work fine in most cases. but here is an excellent link which has more information than i can offer. http://www.sparkplugs.com joe
January 25, 200521 yr Should be a spark plug gab guage/adjuster at the parts shop. Usually right there at the cash register for like .99 cents. Usually they come pre-gaped; I always check. The gap is in your owners manual. I check becuase one time I didnt, threw some new 'pre-gaped' plugs into my Legacy EJ22. Started it up and it ran SOOOO bad. Pulld the plugs; 2 of them were completly closed.... no gap. Other 2 were fine; it was fireing on 2 cylinders =P Would have saved myself 15-25 minutes if I had just checked them before putting them in. Good luck !_!

Most sparkplugs nowaday come pregapped from the factory, so as long as that cardboard tube around the electrode is not damaged, the gap should be correct. It never hurts to check though. Note, these plugs may have a different gap then the standard single (non-split) electrode, so check the box and see if there is a gap setting or go on-line to the NGK site and see if they have a chart. Also, it is best to use a wire type guage, they give you a better gap by measuring only the gap distance at a single point, a flat guage may pick up more then one point and give you a wider gap.
January 25, 200521 yr Don't feel bad, we all had to learn the basics at some point. Some folks never even bother to learn about plugs or anything about the engine, so feel good you are doing this. Good choice of plugs also. If you stick with NGK's you won't have any problems.
January 25, 200521 yr Author Awesome. Thanks for the help. I'm headed out into my garage to put them in right now. Thanks guys.
January 25, 200521 yr In all my past experiences with NGK's, I have found that NGK is pretty good about pregapping the plugs at the factory. But like MorganM and Dr. RX have said previously, it never hurts to check. Just in case the box that the plugs were bulk shipped in got dropped or thrown or whatever.

Most have addressed the first 2questions, which have a definitive answer. The third question, "Whay am I an idiot," has multiple answers which may or may not be correct. 1. genetics? 2. learned behavior? 3. it's within your comfort zone? 4. It's an expected behavior 5. any or all or the above in different combinations 6. none of the above (of course, you realize I'm just kidding you)
January 25, 200521 yr Be careful when starting the threads on the new plug. I like feeling the threads start by just using a plug socket and extension if needed. I remove the socket wrench for better FEEL. After I know the threads are started correctly I turn it by hand as far as I can and then finish with the wrench. I have never had a crossthread problem doing a change this way. Let us know if the new plugs make a difference.
