anyone know of some good performance spark plugs for an '03 Yamaha r6? and what would be some other good performance parts for the same bike? besides power commander air filter and exhaust. anything engine wise?
I got my NGK CR10EKs at the local auto parts store.
Same here. I just bought a set for my '06 at Advance Auto Parts. They had to order them. Went back yesterday and picked them up. I think they were $6.59 each. Had a coupon for $5 off the total price.
