SplitFire Spark Plugs

[Jerrym]

I am tired of changing sparks plugs every 12,000 miles, which is about twice a year. I see where some of you are using SplitFire Triple Platinum plugs (TP416D). They say they are good for 50,000 miles. I sure do not want to screw my engine up is there any problem in using these plugs? I did order 4 of them today.

I've been using them since I read a thread about them here about three years ago, and they're excellent. I think you'll like them. Take one or two out after 12k, take a look and you'll see what I mean.

Your results may vary, but these guys didnt see much.

"RESULTS
We fitted them to the GSX-R - which was previously running standard NGK CR9Es -and it delivered a consistent 1bhp less in the upper rev-range.

MANUFACTURER COMMENTS
Splitfire Platinum plugs are extra sensitive to gap settings, and may need adjusting for the best results. These plugs are used by many top race teams, and have been tested extensively and successfully.'

VERDICT
Don't expect to drop them in and get instant gains. Gapping needs expertise and specialist tools.
NO GAIN"

I picked up a set of NGK Iridium plugs p/n DCPR7EIX that are spec'd for the LT and giving them a try. I got them at Advanced Auto Parts $6.95 each. Hopefully they will be the last set of plugs I'll purchase for the LT. They can also be ordered online at ngk.com or sparkplugs.com.

If you'r tired changing every 12,000 miles, stop doing it. Any plug will go 50,000 or more. I changed my original plugs at 30,000 & they didn't look any differant than the new ones. 12,000 is old school, leaded gas days.

I didn't change mine at the 24000 mile service. They pretty much looked new. However I do plan on changing then at the next interval (30000) and I plan on using split fire plugs. If they are good enough for Dave Shealey, they are good enough for me.

I tried these also. About 1,000 later I took them out and put the OEM back in. Bike did not seem to have the pep it had with the standard plugs. Just my opinion.

I use them on my 91 Suz. GSX1100G, only because #1 cyl. has fouled out in the past after sitting for a day or two, complained to the dealer for months, finally bought some split fires and have not had a problem since,(years now) even this spring after sitting all winter, cranked maybe 5 seconds and popped right off, it runs VERY cold blooded but after a few minutes it was ready for a speed run!!

only have 2500 on my 06 LT sorry Im not much help on that.

When I did my 12K I changed out for new plugs - but the old ones looked great.

So, I kept 'em. I did some *very* light cleaning on 'em, checked the gap and when I do my 24K, they'll go back in.

I'll likely rotate the 8 of 'em that way until I see a reason not to.

I want to thank all you guys for coming back to me on the plugs. I have felt the same on the original plugs. At 12,000 they looked good but I did change them. The next time I went 19,300 and they looked good. I now have 14,000 miles on the third set. I do have a set of SplitFire on order, which I will change but I may wait for a while. It is like checking the values. I checked the valves at 12,000 miles and again at 31,000 miles. They were right on at 12,000 miles and had not changed at 31,000 miles. Is it necessary to check them now at 45,000 miles? The bike runs perfect. It seems to run better all the time.

I would not skip the checks, especially as the miles start getting higher. They WILL eventually start to need adjusting, and you cannot guess when this will start. By about 80,000, all my valves had been adjusted. If I remember correctly, the first needed adjustment was at the 45K check.

So how can the splitfire spark plugs help anything? I just don't get it.....

Very long life, as any Platinum or Iridium tipped plug will do. Platinum on BOTH electrodes has the potential for longer life than just platinum on the center electrode, as many are. The SplitFire triple platinum has one platinum tip on the center electrode, two on the "split" ground electrode. A good many platinum or iridium plugs only have the wear prevention precious metal tips on the center electrode. As the sharp edges of the standard ground electrode wear rounded, it takes higher voltage to initate the spark. Voltage will initate a spark between two relatively sharp edges or points at a lower level than between rounded edges. One having a relatively sharp edge, as in platinum or iridium tips, is still much better than both being rounded, thus standard steel plugs do not last as long.

Just do not pay any attention at all to the advertised "performance" enhancement of any spark plug. Spark plugs either work good, or not, but there is little that can be done to make them work "better" than other good plugs, just longer.
