I know that spark plugs should be changed often, but want to know if I have an MSD, is it going to make me keep them for a longer time......

Your help is appreciated

 

well if you run copper plugs and its a street car i would say every oil change its only an extra $8 when you doing a oil change

 

just get rid of msd i gained 100 whp changin back to oem f-ing msd bullshit traded it to a domestic guy for a cometic head gasket and arp studs

Pretty good idea for the little cost.

When i go to the track i take 2 extra sets just incase im having break-up problems. I used to pull them and check them/clean them between rounds. Now with the retune i havnt changed them in probably 30+ passes and no problems.

It all depends on the tune and condition of the motor

 

my MSD works just fine for me and alot of other people around me, the "problems" do not exist in my area.

 

oh at the track i change them every 2 passes no matter what they look like
