DiabloSport High Output Ignition Coil for Gen III HEMI 5.7L 6.1L 6.2L 6.4L - Single - 3345-HO1

The DiabloSport 3345-HO1 is a single high output ignition coil for the Gen III HEMI: 5.7L, 6.1L, 6.2L and 6.4L engines in 2005 and newer Dodge, Chrysler, Jeep and Ram vehicles. It mounts and plugs in like the factory coil, with upgraded internal windings and materials for a hotter, more consistent spark.

Use it as a one-for-one replacement when a coil fails, or build a full set over time. DiabloSport measured 7.8 rwhp on a 2016 Hellcat at stock boost with a full set, and reports better throttle response and cold starts over worn factory coils.

Frequently asked questions

Is this one coil or a set?

One coil. The HEMI uses eight; the full set is part number 3345-HO8.

Does it fit a Hellcat?

Yes. It covers the 6.2L supercharged HEMI along with the 5.7L, 6.1L and 6.4L.

Will I gain power?

DiabloSport measured 7.8 rwhp on a 2016 Hellcat at stock boost with a full set. On a healthy stock engine the main benefit is a stronger, more consistent spark; the gain is largest when replacing worn coils or supporting a tune.
