I ran split fire plugs in my dodge 2 different times, each time for approx 20k miles, never had a problem, felt that nice little extra kick in the pants from them when they where new, and fuel milage increased slightly when I switched over to them.
My last set of plugs were recomended to me from this site, I think they were autolights, 3920 possibly. Never felt anything more from them, not like new plugs should have felt.
So today I went searching for the V cut Split fires and it seems they have been discontinued. Some sites still advertise them but the official splitfire site does not, and they r the ones who said they r discontinuied.
So Im looking for any recomendations.
From the little I read, looks like NGK V-Power or G-Power may be good options, anybody use these in there vans.
I plan on using the same brand in my astro also.

I use Bosch Platniums in my '94 Dan. Running great after 40K plus miles since I put them in. Bosch also has those Platnium +4 plugs.
I've had very good luck with Bosch plugs.

Bosch plugs are okay in certain vehicles - they're horrible in my '89 240sx and are absolutely not recommended for the Astro (I've got a '93).
AC Delco platinums supposedly do run well in the Astro, though. Haven't tried them, I run the standard AC Delcos in mine.

You might find the Splitfires you are looking for on ebay.

Dan..also I think we have a spark plug distributor here on Dodgetalk. Check the sponsor area. I believe it's Sparkplugs.com
Yes Leeann...I run AC Delco plugs in my GMC van and have in all the GM vehicles I've owned. Champion plugs were OEM in Mopars for many years, but not sure if they still are. I personally do not like Champion plugs.

I don't, either - never had any good experiences with them :werd:

I never like champions either, always used delcos and autolites until I tried those splitfires.
Im just a little worried about going back to splitfires if they were discontinued. I did already see them on ebay, but also read about people having engine problem due to them, so I think I will stay away now even tho I did have good luck with them.
I would like to find the same type of design plug from another manufactuer if they exist out there. The NGK V Power is a different design but the same concept I guess u could say. Just wondering if anybody has used them. I have also heard that platinums dont work great in all types of vehicles, so Im a little lerry of them to. Hate to spend so much and go though all the work just to be taking them back out.

Bosch 4428. With your 8 mm set and MSD. Sweet! Got an extra mile or so per gallon but the performance .... Got to love that Number one plug though .... still have a scare from the removal of the old one .... #1, 3 .... Man ....

The reason some plugs probably work better in certian vehicles is the internal resistor is of the correct value.. Most new vehicles use coil on plug and need different resistance values... It's a compromise for plug suppliers to say it works in more than one application.
Also some plugs come with the screw-on adaptor so they can be used in multiple applications. If they aren't tight they eventually oxidize at this poit and don't function as well over time.

Rather than RE-HASH, here's the thread on the plugs here in the forums.
Also, it was mentioned that the Autolite's can be Side-Gapped for more power and a cleaner burn. That's basically what those expensive Split Fire plugs do in general terms. Side-Gapping ... http://performanceunlimited.com/documents/plugsidegapping.html
Buyer beware, not all platinum plugs are created equal. Read the previous thread discussions on that. ;)

Thanks Stev for all that info, helped, even tho my eyes hurt now. I read that all the last time it was posted here, but forgot all about it, great info.
I think I may go with the NGK V Power and try the side gapping on them. May try it on the astro 1st sine I drive that one each day and Im more likley to notice any differences. If it works out good, then Ill do the dodge.
Simple put Side gapping is cutting the ground electrode off short so the spark occurs from the side of the plug to the center electrode.

I've pondered comparing the side gapping of the Autolite 5224/5223 standard replacement plugs for the Magnum engines vs. the Autolite shortie plugs of 3924/3923.
It seems that the shortie 3924/3923 series sit higher up in the cylinder head while the 5224/5223 sit closer to the head.
If the side gapping helps to determine which series performs better, it will give a better burn of fuel (not wasting fuel out the exhaust) and better energy gain for performance.
So, Dan are you willing to make the evaluation?

I went with the NGK V Power ZFR5F-11 after reading the good info Steve posted.
I also cleaned the IAC which was very clean to begin with, washed and will re-oil the K&N filter, cleaned the PCV, cleaned the Throttle body which was also very clean and poured a little Marvel Mystery oil down the TB too hopefully clean the intake and injectors. Put some in the tank with a small amout of fresh gas.
Next weekend will be a fully synthetic oil and filter change with complete chassis lube.
Also gave the chassis a good washing too.

This past weekend I side gapped the wife's 2005 Caravan. If it burns all of the fuel properly, then the Hp would be at it's ideal power. With that said, the wife would ease up on the gas pedal some. Thus a possible fuel savings. ... One can hope. ;)

Will do! Currently it's getting 20.8 on the digital fuel reading. After two or three fuel tank runs it should average the numbers to reflect the change. I'll know in a month.

Steve what have the results been?
I may even try this side gaping thing to my next set of plugs.
