i got a 98 gsr and i was wondering how u supose to put in the spark plug. do u screw it in all the way? anything i needa know before install it. and i bought some cheap ngk spark plugs for like 2dollar a piece. is this good enough?

 

*SLAP*

ok now that i got this done... um ok so you take out the old spark plugs, and then you take your new ones, and make sure they are gapped properly (gapping tool!!!) and then you take your new plugs and screw them into the engine using a spark plug socket. i tighten them enough that when it starts to get hard to tighten them, i try a quarter turn more.

what kind of ngk's did you get?

 

i got the V-power copper core one

 

you would do best to go with a platinum plug with your engine. copper would make a hot spark and you could be prone to detonation and "pinging". the platinum is a colder spark, which would probably be best for your GSR
