Review on ACCEL 4040 Spark Plug Wire Set 8mm SUPER STOCK GRAPHITE UNI, Yellow: Performance-boosting Ignition Wires for Enhanced Engine Efficiency by Domonic Roberts

Revainrating 5 out of 5

Whatever the reason, they worked very well.

I bought them because the silicone boots completely cover the spark plug insulators. Excellent for air-cooled engines where dust and dirt can form leakage paths through insulators. I installed them in an air-cooled VW and to my great surprise the engine seems to have more torque. The motor is equipped with a premium Bosch coil and electronic crossovers, so ordinary cables couldn't withstand the increased voltage? Whatever the reason, they worked very well.

Pros
  • Weight
Cons
  • Easy repairability
