is this a good spark plug or not
does it go bad quick or wat
wat do yall recomend

 

They last forever, but I change mine out once a year anyway. I am getting a slightly snappier throtle response, running Iridium.

I can't locate it right now, but on this site ( http://www.sparkplugs.com/default.asp?KID=39 ) I found some dyno results that show more torque and horsepower running Iridium, vs other types of plugs!!!

 

I have noticed no performance difference(starts & response), and I am suprised that anyone could document a gain in HP in a bike that has no ignition or fuel delivery issues. If you have complete burn, with any plug, how do you gain HP? (Not disputing the claims, just was not my understanding of their benefit). The advantages are supposed to be they will fire with less resistance. Thus, may have a better ignition kernel where there is a problem in the coil and CDI. Also, they can make your ignition components last longer, as they fire more efficiently I run them in some old bikes, with questionable ignition components. Again no noticeable difference over a platinum powersports plug, except maybe more resistant to fouling. (The jury is out on the fouling) They run in the same heat ranges, and if they do not foul, should last forever (relatively)

The disadvantage is finding them, and cost. I ordered them on line through spark plug 411, w shipping makes it a 12$ plug.

X2. Tried palts, rids and whatever. Went back to NGK and used $$$ for go fast parts that make a difference.
If you want to get tricky, just take a NGK and snip off the electrode a bit and side gap it.

 

I've always used the stock plug that came with the bike (not the actual plug LOL, I change it every year, but the same number).

 

I finally found the link with the dyno results. The increase is 2.5hp and around 6 ft/lbs torque (not that much of a difference on a car), but the methods are objective and it would be hard to argue that this is bogus data or some kind of fluke.

If you take the part number to Advance Auto Parts, they can order them for you for around $7.00. I stocked up on several of them.
