Need help with new plugs

[CABimmer]

I have been running NGK BKR6EQUP for several years and want to go with another plug.

I have been getting missfires at the track and want to go with something else. More of a performance plug.

I was thinking of the NGK iridium plugs, but Im not sure which one to go with.

BKr6eix
DCPR7EIx

Any other recomendations would be great.

I have a brand-new set of BKR7EIX (NGK Iridiums), that are specially meant for track/spirited driving use. I do neither.. for now ;) .. so if you're interested, I could give you a deal. Thanks.

I have the same plugs as you doug and notice the same problems in the high rpms.
How much are BKR7EIX plugs?
