BR9EYA Vs. BR9ES

Whats the difference between these plugs and can you use a br9es in place of a br9eya

ES is more prone to fouling.

EYA is what a Firecat needs, but I prefer the BR9EIX Iridium- they will work in place of either plug.

Ditto. I've changed them before I've fouled them.

For what the BR9EIX costs, I can replace 4 EYA's. Been running EYA's for years with no issues. Change at beginning of season although don't have to.

Or how about this for the answer to your question! Br9EYA, its spark is actually a Y, the spark itself splits. The BR9ES; the spark itself resembles an S. The br9eya is in my oponion a better plug, twice as much spark as far as im conserned. you can run br9eya's in a sled that requires br9es, if the sled requires a br9es and you run a eya, it wont run for shit...

all educated guesses!!

hope this might help

Dont guess if you dont know...

EYA is an ES with a "V" groove in the electrode, they dont foul as easy, and cost about the same,(as of today msrp from cat is $2.95 ea)

If you need to get home you can use a es with no problems, if you are going to buy plugs dont be a cheapskate get the eya's

Well, sort of, the "E" is the plugs reach (3/4" or 19 MM), the "S" is a standard center electrode, 2,5 MM electrode, the "Y" is a V- groove center electrode, 2.5 MM insulator, The "A" means special design. Spark plugs have no spark or heat of their own. Spark is determined by your ignition system type, and a plugs heat range is measured in the plugs ability to dissapate heat, not accumulate it.

The reason i was wondering is because somone gave me a hole box of br9es'

well said, i had to go look it up shortly thereafter. as said before, br9es will get you home. br9eya is the one to go with, shell out the extra buck and get the right stuff
