NGK、BOSCH、DELCO is all ok for normal use. but if u want high performance like high hp cars. use NGK 白金, Bosch 白金 2+ or above. since they produce stronger spark, specially when the rpm is high.

G' I5 I6 x7 r3 ebasiclly the more expensive plug produce higher performance and reliability. i am using Bosch 白金 2+ for my 2000 civic, since it is the highest grade i can go, Bosch stopped to produce any 4+'s. .........but in my acura, i'm use 4+, to maintain the performance i needed.
