1988 Chevrolet R20 Suburban Spark Plug Wire Set 8 Cyl 5.7L MSD

I used these wires on a 68 Ford 302 along with a set of Made For You vertical wire looms. The angled spark plug boots allowed room to clear the headers. The crimp tool that came with the wires works great as well. This really cleaned up and organized the engine bay.

awesome set!

Great set of plug wires with a great look. Only get 4 stars though, because the coil to center post wire will not fit under the OEM TPI cover.

At the age of 66, I've purchased many sets of spark plug wires from different companies. From experience, MSD makes the most reliable top quality and long lasting spark plug wires compared to any other brand.Purchase a set and you'll never use any other brand!!

Exactly as the description said. Fast shipping. Arrived here on time. And the product is outstanding. I love it. Can't go wrong when buying msd

I bought this set for my 1993 Ford F150. This wire set is high quality. I like the fact that I can make the wires the exactly length I need. The strip gauge and crimp device works like a charm. It is very handy to have a small bench vice in order to use. I could not imagine what a pain it would be without. they give you plenty of length for any routing that you may desire. I chose to make as short as possible for each. i think i had enough wire left over to do a set of wires for my 4 cylinder car. The end connectors snap on the distributor and spark plug very nicely and securely. My engine has no hesitation now.

Comes with a way to number wires with a numbered plastic clip collar. I have pulled these on and off and they do not break or come apart like cheaper wires might. Performance has been excellent, combined with a MSD 6al, MSD blaster coil, and a new cap and rotor.

I have a 94 camaro Z28 LT1 350 and these cables that fit perfectly, but you have to properly put the wires in a position that are not touching the manifuls and exhaust, worse everything else feels revived and more with the MSD 8381 , accelerates like a beast all.

I picked these up on an amazing deal offered through AutoPartsWAY Warehouse. I was surprised by the quality of the wires. They are built very well and it comes with an awesome bonus. It may not sound like much, but it comes with numbered tags so you can label each cylinder. This is very convenient if a wire ever comes loose or if you are moving them off for another project, there is no more guessing.I cant say for sure how much they increased my performance because I replaced the plugs, cap, rotor, and pcv valve all at the same time.

You promised that the MSD Ignition wires would fit on a 1994 Corvette LT-1 engine and you got it here fast...but seems like you might have cross referenced the companion order of the MSD LT-1 distributor cap and rotor (an Opti-spark replacement for an LT-1 and not a conventional distributor for which the 31249 set you sent may well be suited). The MSD Performance website guided me to set pn 32179.

It's always nice when you order something and its exactly what you wanted and shows up super fast! would totally buy again.

if you want 20% increase in gas mileage this the way to go , these msd wires are very good quailty

I needed several styles of boot to clear my headers and this product does it as it lets you bend the boot to where you need it to clear. 4 stars because no wire looms come with it.

These are exellent option which offers low resistance. Unlike the NGK OEM ignition wires which has a really high resistance accross the conductor. These have 40 to 50 ohms per foot. NGK has over 1000 Ohms. I was skeptical so I had to do some measurement on all conductors and the test result showed each has over 2000 ohms on the NGK. MSD showed just little over 100 ohms which is exellent!!!!!

You get what you pay for with wires and these are super well made high quality wires that should last long time. They fit my small block chevy motor with headers fine.

These wires are a little long. If I was working on a show car I'd prefer to buy a set I could cut to length. For the price they were a good value...low resistance & fit better than some I've used. They were tight but still fit in the factory Ford holders on the valve covers.

Got these for my 2002 s10 4.3L and it was a good fit along with the iridium plugs. I just wish the were Red like the picture, you get Black wires.

Great product. I paid a little more for the wiring kit than I should have. It was mostly a shortcoming on MSD's website where if it didn't understand your engine, it would default you to this. I could have saved 30-40 bucks just buying fully premade ones for any other small block ford, but now I do appreciate being able to shorten/lengthen and route cables to give the engine a really clean, finished look.The wires and connectors are great and of true MSD quality.Resistance was even better than advertised, sometimes just 2-3 ohms, but never more than 10 for any wire.The kit comes with 8x 8.5mm wires (standard is 8mm) that have the spark plug end on them. You cut it to length and put the distributor end on with the included tool. Instructions were confusing but just follow the pictures and you'll be fine.This set is the only option if you want to have great looking custom length spark plug wires.

Wires fit fine on a 460 with a Mallory Unilite distributor. A little on the long side, but better than too short!

Wires Look great and work decently. The only bad thing I could say about them is that the heat really effects them. Mine are starting to fade and look like they are starting to chafe.

I'm always apprehensive when I buy "custom fit" plug wires. But this set fit pretty well. The coil wire was slightly shorter, and the #8 wire was about 3" too long. In my opinion, the overmolded boots at both ends exceed OEM quality. The insulation is large, 8.5mm, compared to the stock diameter of 7.0mm. Due to the diameter of the insulation, expect to modify all of the plastic wire loom holders and the metal shrouds that cover the boots near the exhaust. This means more work, more frustration...but everyone that changes wires on a LT1 would only like to do it once. This is a small price to pay for the gain, as they are "Super Conductor" indeed. I measured the resistance of my old wires and this new set. An example: my old coil wire was just shy of 4,000 ohms....the new coil wire: 34 ohms. Huge difference!
