I was planning on getting a ngk spark plug for my 95 foreman 400
is there any advantage of getting one?
do i have to get one for a trx400fw or will a mathing car one do?

If you mean the NGK Iridium, it's supposed to provide faster starting, run smoother and not foul as easily. I haven't really noticed a difference in how the bike runs but I figure it can't hurt and it will probably keep running fine longer if it's not likely to foul as easy.
The stock NGK plug is DPR7EA-9. Can't remember what the Iridium # is but you can cross reference it at an auto parts store.
