help with spark plug selection

[luk909]

Im changing my plugs and decided to get ngk bpr6es because of the price, im used to runnung bpr6ekn's but the damn cost. My car has 550cc injectors a big 16g , front mount, 190lph fuel pump, i dont have my boost controller hooked up so its only running 10psi, should i keep the bpr6es's or go with the bpr7es's

6es.

 

[THE REAL DEAL]

the 6es plugs should be fine

With that kind of boost you'll want to run the 6's. When you get around the 18 or so mark then switch out to the 7's. Was just wondering what type of plug the ekn's were, don't recall that designation?

the ekn's are double prong that go around the electrod instead of over the top.

Ahh, got ya, never knew their number. The es's are proven to work great in our cars, no need to spend the extra on the ekn's I guess more expensive isn't always the best route

The factory plugs were the EKN. I've never heard of any drawback to switching to ES plugs.

I was just wondeing about this. I just replaced my plugs with 6es's and the ones I pulled out were ekn's. I nkow that the 6es are the recomended for our cars, but the ekns do the same job and are not anything special?

from what i understand, theres not much difference except for the price.
