u can use BP6ES plugs {about $4 ea}
but use either PFR6J-11 platinum {about $15-20}
or BPR6EIX iridium {about $12-16}
if u want u can change them to a 7 instead of a 6 but not really necessary if u only have the 8.X:1 comp
obviously platnium's are better as they can go for upto 100,000k without changing anf iridium's can go for 70k or so and the std's can go for 30k or so
but if u decide to go for the BP6ES, make sure u can put non resisted plugs in.
otherwise go for BPR6ES
