2-3 hp with plugs

[LazyBastard]

Anybody do any testing on plugs like IMR9C-9H? No 10 available to best of my knowledge, though might be on special request. I=iridium, M=10x19 threads and 5/8" hex, R=resistor, 9=heat, C=special, 9=0.9mm gap, H=???. These plugs are laser welded and have a concave iridium ground electrode, apparently to direct the spark to the outer edge. They're $15 for 4 http://www.bikebandit.com/product/A5370787 .

Re: HP

I honestly don't beleive a fraction of the claims of horsepower with plugs, air box mods, etc, etc If I added all the mods up on my Firecat I must have been 180hp?
I think the best advantages yet are clean belt and clutches, track set to right tension, ride height, etc,etc or loose some weight. LOL
Thats why I'm adding one thing at a time to my apex and will know what it does.
Just my opinion.

>>>
Remember not everything makes it's H.P. increase over peak stock h.p. , Example: it might make 2-3 h.p. more in the 7000 to 8500 rpms but the PEAK 150 H.P. won't change. Here is an example Ulmer Racing can prove via Dyno that the PCIII , ignition module, air box mod and plugs make 10 h.p. over stock and that is a great achievement for these 4 strokes with bolt on items. Now add a pipe , a new intake cam and some head porting and your in the 178 to 180 h.p. increase but these all have increase's and some even decreases over stock in certain RPM'S. The point is nothing is as black and white as it may be advertised but that doesn't mean it don't work .

Actually Yamaha is using them this year in the new Phazer model. Gade-thrasher, the plug is the same for the 3 cylinder. For any Apex guys make sure you get the caps for the tips of the plugs as the Apex uses a solid tip plug stock so you'll need the threaded caps.

So they are good for the nytro also ?
