Reviews for RIPP Superchargers 1118CPK36 High Performance Coil Pack Kit for 12-18 Jeep Wrangler JK and 11-15 Grand Cherokee

Installation is only a pain because of everything you have to remove to get to the coils. A buddy and I did it in less than 2 hours, not less than one, your mileage may vary if you can remove everything faster than we did. Performance is noticeably better - throttle response and acceleration vastly improved. No idea on fuel efficiency yet.

RIPP coil packs are garbage. Caused a misfire and the rubbers are flimsy. Sent them back and getting a hard time about a refund. They zero miles on them. They’re a 20 percent restocking fee for return items. Buyer beware

One of the coils is defective and caused a misfire in my 3.6 Pentastar (2nd Generation) Engine.

I agree with Bob S. I had one fail not 30 days after install. To RIPPS credit they sent out a new one and I just has a second one fail and now I am without a jeep for a hot second. Save your money, these aren't worth it.

Ripp-off! 2 failures in 30 days. Was told they were aware of manufacturing issue. 33%failure rate is unacceptable especially when you don’t know when it will happen or where!
