Perfect fit and functionality

Product fits like OEM. You'll need to buy extra dialectical contact grease to make sure they have a good connection and don't corrode. I connected them to original NGK coils and spark plugs and everything ran smoothly and works well. Definitely mine it again.

Pros
  • For use as a secondary amplifier
Cons
  • Fits

Worked fine on a 2011 Durango with 5.7

Couldn't tell them from the originals, I think Denso might be the OEM for these things. The dealer wanted to sell me the whole set of coils for $100 each. Installation was easy and I would definitely use it again. The package contains all 16 parts needed for 5.7 HEMI® and a small packet of dielectric grease.

Pros
  • Makes installation easier
Cons
  • I vaguely remember

Depends on your vehicle.

I bought these for my 2006 Dodge Charger R/T. The car has done 90,000 miles and I had it checked by a road mechanic and the manufacturer. This particular vehicle is sensitive to some spare parts, these must be Mopar parts. Hemi engines can get a little messed up. I bought Mopar spark plugs but couldn't get coils from the dealer because they're $62 a pack. By pack I mean 2 total. So you need 8 packs to get 16 which will cost you around $500 so I decided to buy them as they were a lot cheaper…

Pros
  • Produces strong sparks in a very short time
Cons
  • I don't remember but there was something
