DIC0136 DENSO Ignition Coil

The Ignition Coil from DENSO (MPN: DIC0136) is sourced from Japan and has supplier-listed dimensions of 80 x 100 x 200 mm. It is typically used within the Engine Parts > Engine Electronics > Ignition Coil category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. Ignition coils are inductive components transforming low-voltage primary circuit electricity into the high-voltage pulses needed to create an arc at the spark plug gap. These coils are integral to both distributor-based and distributorless ignition systems, commonly located near the spark plugs or within the engine control module housing. Modern designs utilize primary and secondary windings with specific resistance values to achieve required dwell and output voltages. Coil construction varies, employing materials like ferrite or oil-filled casings for thermal management and dielectric strength. Failure modes typically involve open or shorted windings, leading to misfires or no-start conditions, and are diagnosed via resistance measurements and visual inspection for cracking or arcing.
