Quality stuff. Great customer service. Fast responses to emails and very helpful on the phone. This is how companys should be ran!
James S.
Easy installation of the spark plugs, wires, and spark box, highly recommended for those wanting/needing a hotter spark. Also, a relatively inexpensive upgrade (eg, no internal engine work needed.)
Brian D.
Easy to install and works!
Jose T.
Easy to install and adds strength to the Jeep.
Geovanni V.
Better than I expected
Jim M.
Installed at the same time as headers and tuner just replaced due to time and mileage. Could not tell which item made the most difference for power.
Virgil R.
I have installed it and the fuel mileage has increased by 1.2 mpg. Has 58,000 miles on the 2007 Rubicon with 37 inch tires and a Teraflex 4 inch lift.

Good quality product !

True plug and play experience. Pulled the worn out factory plugs, installed the packaged NGKs, and I could feel the difference on first crank and idle. Idle is smooth, throttle response is crisp, and the engine sounds like it’s supposed to. Can’t wait to get the rest of my mods done.

Easy install overall. It can be tricky getting the spark plug wires around the back of the engine. More dielectric grease than provided would be an asset. Before install, I was experiencing misfire codes at higher rpm's and heavy pedal. I don't have those issues now. The bottom end of the throttle response suggests increased low end torque. The mileage has increased, but might also be attributed to new AT tires. Also, for the aged like myself, placing wire numbers on the coil pack would eliminate referencing the old factory part. I'm pleased with the kit.

Parts look great waiting on supercharger to install. Fast shipping.
Darrell B.
Nice complete tune up kit.
Eric O.
Greta product. Straight forward install. Runs smoother, better idle and 1-2 mpg increase in mileage.
David S.
Great product! Would be nice if they gave a larger pack of dielectric grease with it but definitely feels like a solid product
Matt C.
Awesome product. Noticed improved gas mileage. Smoother running and more power.
Blaine Y.
Install took about 30 minutes, everything was easy enough other than it was a little difficult re-running the plug wires back around the rear of the engine like the oem ones where, haven't noticed any power gains but I'm already not geared correctly.
Fabian L.
Great addition! I can see a big difference. Totally recommended the update.
Ralph R.
Easy install, seemed to wake up the N/A 3.8. CAI/Tune and exhaust combo.
Brandon B.
So I haven't drove the jeep a whole lot but from the minute I installed it I noticed instant power, also my jeep stopped drinking gas. I went from filling up the tank every 3 days to a little more then a week. I'm super impressed with the coil pack it impressed me. I am thinking about the super charger next but it's a little pricey.

Customer Service, installation and most importantly product design are all 5 Stars for this 2011 Jeep JKU Owner. My Jeep was in dire need of its 96K tune-up which included Spark Plug change. Wanting more out of my vehicles low end performance I decided to purchase the R.I.P.P. Spark Plug wire, coil pack and spark plugs. I am thoroughly impressed by the quality of all 3 items. The install isn't hard at all(with the right tools and patience). Besides it looks bitchin when I pop the hood. No more rough idling and definitely feel somewhat of a pickup. I wasn't expecting it to act as a Supercharger, but "hey what can we expect from our 3.8l V6's?" Fortunately mine is a manual, so that gives me a small boost, Ha!
James G.
did what i expected .. look good on the engine too.
Marty M.
I was skeptical at first.
Easy to install. Improved performance, and gas mileage.
I would recommend.
Marcus P.
Very well prepared kit. Simple install explanation on the Coil box.
My plugs were a little worn, experiencing >10% consumption gains.
Gabriel R.
Very easy install and the product is top notch quality. I've definitely noticed a big difference in performance and they way my JKU runs.
Andrew G.
Everything went together nicely and all works well
Brad R.
Installation was very straight forward. Engine starts and runs some much smoother now! I’m very impressed by how much better the engine idles and how much crisper the throttle response is.
Richard M.
This upgrade was a definitely felt.
Andrew C.
Quick easy install. Necessary on a JKU almost 10 years old. Spark plugs were ready to go! Thank you RIPP.
Christopher I.
Restored performance in my jeep after installing long tuber headers.
