Spark Plug Gapping Tools
Spark Plug Gapping Tools Hey guys i would like to know what everyone is using to gap there plugs. Im looking for a reliable and spot on tool. I've seen Summit Racing and Accel has a pliers tool.
I just use a feeler gauge. If its good enough for the 90 million dollar v22 osprey, its good enough for my spark plugs.
...I really haven't heard any praises of said spark plug tools though, FWIW.
From one Marine to another ;-)

ya i get that, i use a feeler gauge to "check" gaps. but im asking for actually gapping tools. Or do most people just use needle nose pliers or push the tip against something to actually change the gap?
On copper and platinum tip plugs, I just use a gapping tool that I got from SnapOn that looks like a screwdriver, but with a gauge on it, and I pry upwards on the ground. If gapping an iridium plug, you can not pry as you may contact the electrode and snap the micro welded iridium tip off, in that case I use needle nose pliers. To close the gap I just push against something solid, like a vise.
I've got a Snap-on, Matco, and Craftsman gapper. They're all pretty decent. The Craftsman will be the cheapest and most accessible if you don't visit the tool truck that often.
Whatever you do, don't use or buy the elcheapo gappers they have sitting next to the registers at parts stores. Those things are junk and inconsistent as hell.

Verdad Gallardo funny i cant seem to find an other gapping tools than the generic ones (2) i found on Summit's site. I looked on Matco, Craftsman and Snap-on websites.
all ive seen are the gap gauges and feelers

tiny screw driver to open up the gap then feeler gauges to measure the gap. I searched this same thing about 3 months ago and came up blank, I started talking to guys running mid 9s and they recommended feeler gauges as well.
I've used this Lisle gapping tool for many years, the 'fingers' at each end are used to gently twist the ground electrode in or out until the proper gap is reached. I thought every tool box had one of these.

i've had the best luck with the ones that actually bend the ground strap back without touching the electrode. best way to go IMO.
