MSD 32819 Super Conductor Spark Plug Wire Set, Red

These wire are extremely high quality. When tested with an ohm meter prior to installation, they registered @28 ohms. The stock wires were Delco, and registered over @800 ohms. The Delco wires were 7 years old, and were causing our LS-2 equipped 2007 Corvette(15,450 miles) to misfire at idle, and also while cruising. This was to be expected with OEM wires. The MSD wires, right out of the box are too tight a fit. I called MSD customer support, and told them these wires needed to be about 1 inch longer. However, the tech told me the MSD wire spark plug boot was designed to be bent up to a 45 degree angle. I was amazed that this feature was built into the spark plug boot. I did what they instructed, and this wire set fit perfectly, and still checked out at @28 ohms. There were no printed instructions or directions on the box telling me of this ability to bend the plug boot for a perfect fit. The tech promised this would be corrected. The low resistance is created, because the OEM style carbon core is wrapped with copper wire. They claim @ 30 to 40 feet of copper wire per foot of ignition wire is would around the core. One would expect the copper wire to cause interference with the radio and electronics, but just the opposite is the case. This style of wire is also known as Magnetic Suppression Wire. There is a very small electro- magnetic field around these wires, and with the copper windings- very little resistance. The Corvette started immediately, the idle was smooth once again, and the acceleration was noticeably "crisp" and strong. These wires should last a lot longer than 7 years or 15,000 miles- truly a value for the money and they are American made!

Put these bad boys on my 2000 camaro ls1, definitely picked up some power, around 100 ponies or so, MSD quality is there like always, somewhat but not to easy to install if you don't know what your doing, get you some MSD plug wires to win that next race, i paired them with some NGK TR55 plugs

These fit perfect on my NNBS 07 silverado. Needed new wires when installing some long tubes and these are great. You can fit these on the trucks just make sure you have the same style coil packs or else these wont fit since the wires are short.

I have no bad things to say about the wires. They just barely reach, but the truck has better response than my old delco wires. I have a very negative experience with MSD and a very positive experience with Super Shops. I bought the MSD 32819 wires for my 2007 2500 HD based on the fitment guide and application page on MSD's website. The site listed these as a direct fit for my truck. However when I put them on with new plugs and coils they were pulled tight enough to play like a guitar and all 8 boots were pressed up tight against the exhaust manifold bolts. I called the MSD tech support line and they said that the correct wires were infact the 32829 wires which were listed for Savanah vans and made no mention of the last model 6.0L. The tech guys said they were aware of the problem and how it would mislead customers but nothing was being done about it. They advised me to return the product and work through the vendor which directly contradicts the return information in the MSD box. I contact SUPER SHOPS through amazon and their customer service was phenomenal. They said they had no control over the amazon's fitment guide but were aware it wasn’t correct and were happy to send out the proper set of wires.

Installed as replacement/upgrade on my C5 Corvette. Stronger and more rugged than original plug wires. Larger wire size for stronger spark. like the red color of the insulation which matches the color of the car. Good value.

All was good for 1 50 mile drive next drive car started misfiring. This is LS swap Chevelle all new parts. Had Taylor 409’s installed from 0 miles they only had 2700 miles on them. I replaced the plugs and went ahead and did wires also. Car show season is coming so I like to keep it and new looking. Ohm checked each old Taylor wire 234-238 Ohm checked the new MSD wires 31-32 each Once misfire happened I was scratching my head and figured the car has ran perfect every time I’ve drove it. I’ll check the wires and plugs pulled the wires and ohm’s on 7 wires 31-32 and had one 219 ohms. No need to pull the plugs so I stuck the Taylors back on and the car runs perfect again. called MSD about a warranty they said not on Amazon. Guess I’ll hang them on a shop tree. :( Amazon refunded the purchase!!

10/10 recommend. I purchased the used option and wasn’t disappointed. Even used they came in basically brand new for like $30 off. Can’t complain even a little.

2018 SS Camaro with LT1. At 40000 miles change wires to these MSD wires and to NGK plugs and could instantly tell that the car was much more responsive and smoother idle and did great on the 6500 RPM pulls I did so far so I would recommend changing to the wires with whatever plugs you're using. Also the longer plug end of the wires were more flexible and made a much better fit with the 2 inch long tube headers in my car, perfect length so not as much extra wire like the OEM wires.

جودة ممتازة

Los cables son demasiado cortos , los compré para una silverado 2006 5.3 ! Y son demasiado cortos, no quedan de ninguna manera ! Tenía muchas espectativas sobre el producto ! Lo Cual me decepcione bastante ! Una pulgada más largos que estuvieran y ajustarían Perfecto ! Pero es preferible ahorrarse una pulgada de cable , que tener muchísimas más ventas

when i got these some of them weren't in spec . i checked the resistance on all of them and half of them were not in spec i return the product to amazon and they gladly shipped me another set who all of them were in the 40-50 ohms that msd calls for.i guess i had a bad batch? all in all ;very good shopping experience, it fits my 2014 6.2 ls3. very good. it fits also the ls1 too.

سيئ جدا ولا انصح به لم يكمل سنه وتآكل من الحراره

Works as intended
