DiabloSport High Output Ignition Coils for Gen III HEMI 5.7L 6.1L 6.2L 6.4L - Set of 8 - 3345-HO8

The DiabloSport 3345-HO8 is a set of eight high output ignition coils 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. They mount and plug in exactly like the factory coils, with upgraded windings and internals for a hotter, more consistent spark.

Who should buy these: anyone with a high-mile HEMI still on original coils, anyone running a tune or more boost than stock, and anyone chasing a misfire under load. DiabloSport measured 7.8 rwhp on a 2016 Hellcat at stock boost. Need to replace just one? See the single coil 3345-HO1.

Frequently asked questions

Does it fit a Hellcat?

Yes. The set 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. 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.

Is hardware included?

No. The coils reuse the factory bolts and connectors.
