Spark Plug info

So how about the new E3 spark plugs? Any one tried these in a cfi yet?
I read some reviews and none of the reviews I read were able to see any increase in gas milage or HP. In fact some saw a reduction in gas milage. If they are good they will be here a few years from now and the Hard core racers will be useing them

Anybody find the infamous NGK BPR9EV ?

Not surprised..I saw other part no.s in Gold and they were all around 24-26.00 hard to sell when they are that expensive. Should be some somewhere stockpliled in a Barn somewhere.

deepdiver, the jetting on the 600's needs to be done for a stronger running engine and better fuel economy. I went with 40 pilots and needles dropped to #2 from top, and once the temps stayed above 10*F for good 390 mains. Best fuel economy was about 15mpg, and this was in crappy conditions with slush and lotsa water. My best buddy has a 600CFI, and I got better economy than he did and I was busting trail all day long.
And I have heard that the 700/800CFI's were excellent on fuel, not the hogs that those bash them say they are.

You hit the nail on the head with those carb adjustments. Also a pipe and can from SLP will help clean the botom end up. With these alterations you should run with the 70o:) dragon's
 
NGK EV gold palladium spark plugs, have a fine wire (1.0mm) gold palladium center electrode for better ignitability, more power, and enhanced antifouling capabilities. Gold palladium increases durability. Traditional ground electrode.

Gold Palladium

Gold is an excellent conductor of electricity which makes it well suited for a performance plug. However gold is also a very soft metal, therefore the gold alloy is mixed with palladium, (a much harder metal), to form a premium fine wire performance plug with increased ignitability and durability.

The fine wire of the EG (nickel electrode) and EV (gold palladium electrode) Spark Plugs significantly lowers the voltage requirement for firing, optimizing the magneto ignition system.

NGK Fine Wire Spark Plugs feature:

Smaller Diameter Center Electrode Tip
Improves Ignition Efficiency
Better Concentration of Spark for Quick,
Easy Starts
Precious Metals Used in the Center Electrode Increase Ignitability and Durability
Higher Resistance to Fouling
Easier to Spark in High-Compression,
High-Revving Engines
Better Starting Performance
Even on the Coldest Days

B- Meaning it has a 14mm thread size and a 13/16" hex size
9- Position on heat range from 2-12 (2 hottest, 12 coldest)
E- 19mm (3/4") thread reach.
V- Fine wire gold palladium center electrode.
BR9EV - Same as above with resister for improved RFI suppression.

BPR9EV - Not sure what the P is for.

If Polaris calls for a BPR9EV where does it come from or where can you get it??..I cant find it anywhere..does not show up on NGK's web site either.


The P- designates Projected electrode
 
^^Stick with the Champions, I do, the racers DO. Polaris developed these sled with the Champions in mind, dual range heat and a different profile.
 
Don't do it

Put them on my mountain max. Been running the same jetting and riding the same area. Burnt the tips off two of the plugs. Just burnt off. Didn't make a day of riding. Put my spare plug in and ran great the rest of the day. Light brown plug color. Exhaust temp about 1080. The e3 plug has a horse shoe style tang. It just got burned off. May have to run richer with the e3 plug. Not worth the playing around. Back to ngk
 
ya i just used the champoin sparkplugs the dealer gave me and they didnt even last 250 miles in my assault and one of them was all ****ed up and nasty looking. so im gona try ngk next and c what happens
 
The center electrode insulator broke and caused an intermittent problem....At first it would only happen under long WOT pulls and I thought it was a fuel starvation problem....Switched to NGK and put on 2000 more miles with no problems

I used to run alot of big drag style nitrous motors(1500-2000+hp) we purposely ran champions because of the porcelain breaking..it does that when it first hits deto(beats the heck out of getting a piston)....and I have always found that my polaris sleds run better on champions then ngks(foul ngk plugs much easier and will actually die if left idling)..
