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!

Features:

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

Benefits:

• 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
