OE Weak Points

The Weak Points in Many OE Coil Designs Lead to Product Failure

Our engineers identify the OE flaws

We design the BWD® coil to overcome these flaws

We manufacture a more reliable, better performing ignition coil

OE Design Flaw: Polypropylene Cover

The OE metal terminal deforms while the epoxy cures causing the high voltage connection to fail.

SMP Solution: Spring Terminal Design

Standard Ignition Coil compared to original equipment showing the spring terminal design to maintain a solid high voltage connection

BWD® engineering features a spring terminal design to maintain a solid high voltage connection for top performance and long service life.

OE Design Flaw: O-ring Design

When the OE O-ring breaks down it allows moisture intrusion which impedes performance and shortens coil life.

SMP Solution: Eliminate O-ring Housing

The BWD® one-piece design with no O-ring housing prevents moisture intrusion, ensuring peak coil performance and long service life.
