do you have to change the spark plug gaps once fitted and if so what do you gap them to???

i`m sure my gaps are 24 or 25 thou at the moment.

 

do you have misfires....

for me it solved the misfires...or my standard coil was fooked....you cant go much wrong for the money...

 

no my car ran fine but as i`m uping the power again i thought i`d treat the car to a new coil.

whats yours gapped at???

 

I just bought a car a 2wd sapph from on here and it had a missfire on boost, i have changed the plugs but now runs slightly rough at bottom end (say from second into third it will splutter for a sec then be ok) Would a group a coil help me??? Getting it set up soon but i live on the isle of wight so want it running better to get it somewhere.

 

i dont know mate to be honest but i`d get that checked out as soon as you can to be on the safe side.
