Replacement Sparkplug Query

You might want to look at the Autolite plugs. I have about 50 hours on
mine, after years of using Champions. The Champions would begin fouling
within the first couple of flights, but the Autolites have yet to foul.
I've had consistently smoother engine operation with the Autolites than
with the Champions.

However, I don't believe that Unison make a fine wire plug.

Good to know. I've actually been using my mechanic's plug wrench, but I've
been meaning to get my own anyway.

I haven't had *any* issues with fouling, but like I said, most of my flying
has been on primarily autogas. The bottom plugs get a bit carboned from the oil burn
(chrome jugs). I'll be interested to pull a plug now that I burned 60
hours on 100LL on a trip to AK and back.

My other question would be whether or not an Autolite has the same electrode
dimension/gap as the Champion. Can I use the same gap-setting/measuring/wear tools on
them as the Champions?

Yes.

I noticed in a freebie Trade-a-Plane I picked up at OSH that Air Power, a
new division of Unison (866-287-8506), has Autolite standard electrode plugs
on sale until October 15th for two for $17.90. Seems pretty cheap
considering that we put five Champion plugs in the Archer last annual for
$35 each.

Hey all. My Lycoming O-360 is finally in need of a new set of plugs. Any
thoughts on replacement flavors? They're currently massive electrode
Champions, and I
run autogas most of the time so fouling isn't much trouble. PMA'd
replacements?
Fine-wire? Not looking to incite a flame war, just pinging collective
experience.

OK...it's not directly related...but...

I've had better luck with Autolite vs Champion both in small engines
and automobiles....better performance, less fouling.

Interesting that some are seeing this in aircraft applications, too.

Unison/Autolite does make a fine wire.

I have been using Unison/Autolite plugs for hundreds of hours and am well
satisfied. Like others have said they seem to foul much less. Some outfit
in Texas is selling them two for $18. They have an ad in TAP. Just got
mine today.

If they do, I would be interested to know where to find them. No
retailers appear to carry them, and there is no mention of them on the
Unison web page or in their spark plug literature.

I do seem to remember something about manufacturing problems that might have
delayed the sale of Autolite fine wire plugs.
