Reviews for Performance Distributors DUI Spark Plug Livewires for 07-11 Jeep Wrangler JK with 3.8L Engine

I bought these in 2013 for my '08 Unlimited X after started misfiring, turns out factory wires started arcing causing misfire. Had these over 7 years now and they are working great. Bought a '07 and having misfire in cylinder 2, going to replace wires with these and do plugs and cap.

I love em

Excellent product, very easy to install!!! Highly recommended!

very nice wires

I put these in my 3.8l 2011 Sahara JKU. They are much beefier than the stock wires and have built in heat protection. The passenger side of the engine was tough to get the wires off of the spark plugs because of limited access and the wires felt like they were glued onto the plugs (maybe from the engine manifold heat and lack of tune up lube before assembly). In any event I sprayed the spark plug wire boots with lots of silicone spray and let them sit for a couple of minutes and then they came off without further trouble. The new wires were installed with sufficient tune up lube so that next time, they'll come right off. The driver's side was easy to remove and install new wires. The new wires perform as good as they look!

One boot fell apart, and the other one melted. Expensive garbage. I would absolutely never buy these again. Customer service from LiveWires was non existant. This is not related to quadratec.

I bought these wires in hopes that they would withstand the heat of my aftermarket headers. 2 of the wires have burnt through the coating and I had to replace 1 entirely. I have had them on for about 2 years now and when I went to change my spark plugs and previous headers with better quality ones, the inner connection came out of the boot still connected to the spark plug. I will never buy these and probably never shop with quadratec again. The description of the item is false. These do not withstand any heat of that temperature. I had to use something or run them on a fashion that they wouldnt get anywhere near the header tubes. If you are looking to buy some new performance plug wires then don't shop for them here.

Two wires burnt the plug connectors off after a little over a year.

I ordered this product based on the fact that the plug connectors were at an almost 90 degree angle going onto the spark plug. I required this as I recently put aftermarket headers on my Jeep Wrangler 3.8l JK and based on the picture the plug wires were what I needed to prevent them from touching the headers. This item does not come close to what the picture shows (Very misleading)

Ordered this item on 7-9-19 and installed. After a few days the number 4 wire failed so I purchased a cheap universal wire so I could drive. I called and was told the warranty part would have to be shipped from the manufacturer on 7-23-19. I waited another week and nothing so I called again. They forgot to submit and apologized . Now ive waited another week its 8-17-19 on a Saturday so no deliveries on the weekend. I call again as the online order update still has it as still processing? Nothing! Stay away from this product they obviously don't care after they get your money and refuse to send a replacement wire. Not happy with Quadratec either as they sold me this item and don't seem to care either. Waiting over a month is ridiculous.
