Don't use those cheap ones that lancershop sells (looks like a coin). I've heard that when gapping the plugs the coin can scracth the tip and damage the spark plug.

Why not just buy new ones? they're only about 4-5 dollars each

$20 for plugs instaed of regapping when you drive over $250,000 worth of cars seems pretty reasonable

GUYS, stop making fun of the kid, you all had to learn too. none of us were born w/ a spark plug in one hand and a gapper in the other.

omg i can believe none has said anything......

1. if it came with a plastic cap over the end it doesnt need to be gapped and if u do it will hurt it more then help

2. if u bought iriduim/ platium plugs if you gap them then you will scratch the iridium/ Plat off the tip and eathier cause premature wear/ failer so my answer to you would be throw those away and go buy new ones and dont touch them! lol just put them in the car and walk away!

dont buy the lancershop one , cause you find the same gapper at your local auto parts store for like .50 cents

however it does work , you just have to be careful around the tip. using needle nose pliers to gap also works. but the cheap tool measures just fine

Enough already...



...



..


.



Here:

The inner on a copper plug is a cylinder surrounded by ceramic with a bit of the copper cylinder showing. This is all molded in place and doesn't move at all. On a regular plug (not a split fire or Bosch+4 multi electrode style) there is an arm that reaches from the threaded outer part of the plug body up over the copper cylinder and looks like a rotated "L". this is the part that you adjust (bend).

Use a gap tool (on copper plugs any gap tool works). Check the gap. If too big tap on the L to shrink the gap. Tap on the floor, or use a wrench handle, or anything. Just tap not hit! remeasure until it is the right gap.

If too small use a pair of small needle nose to grab the L in the bend and rotate up/away from the cylinder. do this until right. try not to scratch or mess up the cylinder.

*****Iridium plug are done with ONLY a wire type feeler and try not to scrape the cylinder at all!!! Other feelers will bend the tip. You can tell an iridium plug buy the center cylinder. It looks like a mini Hershey's kiss not a cylinder. /\ vs. |-|. You will see what they look like when you remove one of the stock plugs. They are iridium. If you still have the stock plugs in.


Good luck. PM me if you ever need any other help. Glad to see you are willing to try to do something new and learn.

I don't like the metal token one.

This one from sears has a little tool to help adjust the gap and is way better than the token gapper
