Airtex Coil Pack

Airtex engineers nested a black plastic sleeve made of high-dielectric strength material inside the larger secondary winding in the DIS coil to prevent the current from jumping from winding to winding – making it no longer the path of least resistance – coil and module life extended!


  • Highly conductive aluminum towers
  • Segregated secondary bobbin
  • Precision wound copper primary winding
  • High dielectric sleeve (improvement over OE)


  • Extremely low secondary coil resistance
  • The best winding conductivity and durability available
  • High voltage output
  • Minimizes internal shorting
  • Longer coil life
  • Reduces ICM (ignition control module) stress
