ok this is for you partsguys types. the place i buy all my car stuff, because its cheap, doesnt have bpr6es11 ngks, just bpr6es plugs. so i looked at the chart on what the #s mean and the 11 means its factory gapped at 40, and the one without the number? it comes gapped at about 20. im runing the bpr6es in one hole gaped to 40, and it seems like normal.

should be fine. I use the 'Y' insteave of the 'S' version.... it's identical, except it has the "V Power" split....

The only real difference with the 11's is convenience, cause you don't have to set the gap yourself (although I'd still check them before they go in). But if you get the standard non-pregapped ones, they will work just the same as the 11's, (after you gap them). It's all about convenience.

try the john deere dealer, also uses them in the snowmobile.....

The BPR6ES is what Subaru's came with from the factory before NGK started producing the BPR6ES-11.

Just got my set from the dealer and the 11's were all gapped at .041 just the way I like it,right in the middle.They give me a discount so I don't go cheap.Works out the same.

 

 

YES always double check.

I just bought a set and they were the cheapest plug of all sold in the store. And they give me a military discount for time served (military time that is).
