Review on Namura NA 40002R Piston Ring Blaster by Bobby Valadez

I had problems with Namura for the first time. The compression ring broke after about 10-20 hours of driving, they were broken in normally and not used intensively for the first 2 tanks of fuel. I was driving at a quarter throttle when they pulled away, pushed the clutch in, the car stalled and wouldn't start. Destroyed my cylinder and cut my cylinder head. Save yourself the hassle and buy wiseco or oem. Namura is good for four goals.
