I have a 1992 rx7 turbo and I need new sparck plug wires. Should I go for stock ones or get something better? Mazdartix sell a few different model what would you suggest for me? Car has ~310rwhp if it matters.

I also have some ignition problem with the spark. I don´t get spark everytime from the trailing coil if I remember correctly (closer the the driver). How can I check the condition of the coil is it undamaged or not?

Thanks

 

I've got magnecore's 8 or 8.5 mm and they have done just fine. Pay your money and take your choice, but I would recommend the 8 mm.

 

Go with some good sized MSD or NGK wires always works the best for me. and you can test the coil by unpluging the cable and holding it close to where you uplugged it from (no more than an inch away) and have someone else crank the car, if you see a spark jump from the coil pack to the cable then it should be good. (youll be able to tell a GOOD spark from a crappy one) and if your sparks are crappy then change your coil packs. good luck

 

this exact same question has already been asked: link

i read this thread and decided to go w/ magnecore.

 

10mm magnacore are the better chioce. only draw back is trying to get a timing signal off it

 

I hate the magnecore ends, they don't fit the spark plugs very well. And the 90o ends at the coils could be beefier. One of mine snapped at the 90. Good thing I had some left over ends from an Accel universal set (much heavier duty piece)

These were the 8mm KV??? model
