So do we still gap them to .020 for boosted sleds like a ES?

Yes sir.
Whats the advantage to gapping the plugs to 20 thousand over 28 thousands stock ?
I was blowing out my spark once I started running boost and gapping the plugs appropriately solved my problem. That's the skinny version explained ha.
Interesting. I have been running the stock es plugs for 800 miles now and never fouled a plug. Didn't know people still have issue with that.
^^^^^^20 is for boosted sleds

These plugs work for a 12 600 motor as well? Would like to carry one type for both sleds if possible
Yes they work great in all Polaris CFI's. I've run them in 600's, 660's, 800's, NA, boost, etc.
And carb'd 685's.
Just to add one more point to all this, you want to try and always run a "solid" tip in a sled motor, NOT the tip that screws on, I've seen tons of cases where the tip either loosens up and creates havoc with the spark, or even threads totally off and there goes that cylinder. If you must use them take a pair of dykes and crimp the terminal in the middle area to secure them
Foul resistant sounds awesome to me, that’s the problem I’m having with the 850, if it gets just a tiny bit wet or an extra squirt of oil they foul. The one difference I noticed was the stock plug bpr9es is a 10kohm plug and the bpr9eya is a 5kohm plug. If the coil is expecting a certain resistance and it’s cut in half wouldn’t that overdrive coil and likely burn it out?
In 10+ years of running BR9EYAs, have not seen any negative side effects.
