labwork RED 8PCS 1200° Spark Plug Wire Boots Heat Shield Protector Sleeve SBC BBC Review:

Due to the fact that my motor runs hotter on the exhaust than a cast iron stock header, I used a second set of 1800 degree closer to the header pipes.These fix a problem I was unaware of because the motorhome's engine is hidden from view, and all I knew about it was that it occasionally misfired. On 3 cylinders, spark plug wires were completely burnt through.

Car 1200 Degree Spark Plug Wire Boots Heat Shield Protector Sleeve Cover fit for SBC BBC 350 454 8PCS by Shinehome Review:

For all 4 of my vehicles, I will purchase these spark plug heat boot guards. Since all those foxbody Mustangs generate a lot of heat that affects all electrical parts and cables, I originally purchased it for my 1989 Mustang GT. However, I actually used these on my freshly rebuilt engine for my 1991 4runner v6 because the original spark plug wires' boots and some of the wire insulation melted due to their spark plug wire design being so close to the manifolds. A strong metal wire that enters through the boot holes makes it challenging to put on the boots. I used 3M silicone oil, which I also purchased from Amazon, to lubricate the inner boot entry of the boot heat protection as well as the entire boot on each spark plug wire. Even after completing this, it was still challenging to attach the boot heat shield to each spark plug wire boot. I'll agree it's a bit pricy, but if you've ever burned

labwork Titanium 1800° Spark Plug Wire Boots Heat Shield Protector Sleeve SBC BBC 350 Review:

I eventually made the decision to look into the maintenance a prior owner had performed after purchasing a BBC Motorhome.Four of the eight spark plug wires had been destroyed. Perhaps that led to the intermittent misfire?I purchased a distributor kit from Amazon Vendors that included plug wires and a timing advance spring kit.This high heat bootie was applied to those fresh wires, thus I can't see any issues like the smokey dust and shattered silicone I discovered on the plug wires.Since certain cables had a distance to travel back to the distributor, I did install a set of 1200 degree boots above for safety's sake.On the 1988 High Performance 7.4L motor, the factory headers are not made of cast iron. When the motor is operating, my heavy wall steel headers emit significantly more heat. The charred wires were therefore expected.

Denso 671-8163 Coil-on Plug Boot Review:

I suppose Denso may be the OEM supplier for these because I was unable to distinguish them from the originals. The dealer wanted to charge me $100 for the complete coil pack. Install was simple, and I would definitely make another purchase. The package also contained a small supply of dielectric lubricant and all 16 required for the 5.7 HEMI®.

Taylor Cable 46057 Socket Style 90-Degree Distributor and Coil Spark Plug Boot and Terminal Kit - Pack of 10 Review:

I purchased a set of Accel 8mm spark plug wires for my truck, but the terminals they provided were too small to wrap the wire around entirely and crimp it back into place. I tried several times before finally giving up and purchasing these because I was out of terminals. These were flawless. The wire had a fantastic stop at the 90-degree elbow, and the terminal was entirely encircled for a polished appearance. I would advise anyone searching for 90 degree terminals to get these.


They arrived swiftly as promised; I rarely deduct 5 stars. They completely matched my wiring (straight). They seem to be reliable and appropriate for its use. Others have written reviews claiming they burned up, however I believe it was for a different product being used in a different way. I bought 8 tan/beige spark plug wire boots for high temperatures. They were put to use in my 1997 Chevy 454 RV. The preceding wires melted and cracked as a result of extreme heat damage. I inserted these boots and used the same wires to replace the cracked ones. The boots are put on by removing the spark plug's wire and putting them on with the ring on the toe side, bottom, outside, but never over the wire. I came across a lot of people who complained about the ring. To prevent the sock from riding up the wire, the ring is present. Folks, the ring never crosses the wire; it is the end, not the beginning, of the sock. Installing the boot from the distributor, coil, or spark side is not recommended. Although it might come in contact with engine parts, this brilliant product should function well and shouldn't burn. Time will only tell. I could have bought $200 ceramic and silicone wires to replace my spark plug wires. These $20 boots should be useful, in my opinion. In high temperature conditions, the plug wires must be often changed. I am not replacing $200 wires as frequently as I should, but I will replace $55 wires instead, and if the boots are holding up well, I will continue to use them.
