Autozone Double Silicon Spark Plug Wires

[Elroy the Unique]

How good are the Autozone Double Silicon Spark Plug Wires? I bought some for my car last night and installed them.

Their top-of-the-line wires were the Bosch Wires, however, they were all out of them for my car. Does anyone have experience with these Autozone brand wires? They do have a lifetime warranty.

I am not interested in an upgrade (just want OEM spec) and I believe the OEM Wires are about 3 times more expensive?

I've used them in 3 or 4 cars. They work fine.

I had a set on my truck for about 7 years. I had a engine miss and they replaced the whole set about three weeks ago. Didn't solve my problem as it was a new spark plug that was defected.

I do not car for them at all!!! I have had many instances of poorly fiting boots from the Duralast Brand of wires. I used them on old beaters. I also found that they have higher resitance then OEM wires right out of the box! Depending on what company made your car will determine how close they are to OEM!!! For OEM applications I rate plug wires as follows: Magnacore,OEM,Bosch most European cars and Toyota and Honda come with really good wires as OEM!

For a number of reasons, measuring the resistance of a sparkplug wire is not a good way to determine how well it's going to work.

A lot of cheap sparkplug wires, by the way, add a spiral metal conductor around the carbon filament core which appears to your DMM to be a low-resistance path..but the spark finds it to be a high-impedance path.

right, very high voltages do not behave the same as low voltages found on VM/DVM/DMM. A meter will pretty much be limited to finding open (broken) conductors only.

You can use a meter to spot DIFFERENCES between wires, but using them to find the absolute resistance value of any single wire is iffy at best.

I've got them in my 1988 Mustang 5.0 and I've changed the plugs and distributor cap about 3 times so far, with the same Autozone wires.

I used Duralast spark plug wires a couple of times and won't again if I have a choice. The biggest complaint I had is the bad connections between the wire and the connector. Be very very careful when removing the boot from plugs. They won't take much abuse.
