I think is about RM200++ new & ori from spare part shop.
What happen to your plug coil? I think my plug coil also got problem, my work shop told me that most of the time is the back 3 pcs. problem, I'll buy 1pc. to test, I think only 1pc. is problem.
As the title states, I'll selling off my set of TEIN HA Coilovers; pilowball mount camber adjustable. They are in great condition. Good for track and drift. Spring rate is 8kgf/mm for the front; 6kgf/mm for the rear...
