The BEST sparkplug??

[JoesSHO]

Might be different for the V8's, but like Paul and because of Paul's reccomendation biggrin I use the Iriduims as well.

Using E3 plugs and they work great and fit perect. Formerly used AC Rapidfires and they also worked very well for many years with no problems.

i like autolites. the 3924 is the stock heat range and i recently went colder (3923) because of the nitrous im going to use.

honestly, my car runs better with this colder range spark plug without the nitrous. im probably going to end up running them even if i stop using the juice.

Thanks to all!! I used the Ford Autolites. The boots fit tight and I received a great price on them. I need reliability vs. keeping up with the Joanses, as some want.

That's the APP3924, which is what I and many other SHO owners are running.

Autolite XP iridiums. You can almost always get a rebate too.

x2. I've used these on 3 different SHOs multiple times. A little pricey (iridiums always are) but they are worth it and they fit the SHO's plug boots quite nicely and last for ever. :wave:
