Review on 🛡️ Shinehome Degree Shield Sleeve Protector by Adam Gechem

I will buy this spark plug guard for all my 4 cars. I originally bought it for my '89 Mustang GT because all those fox bodied Mustangs generate a lot of heat which affects all the electrical components and wiring. However, I actually used them on my newly rebuilt engine for my 1991 4runner v6 whose spark plug wire design is very close to the elbows that the boots on the original spark plug wires melted, including some of the wire insulation. The trunk entrances have thick metal wire that is difficult to thread into boots. I used 3M silicone grease, which I also purchased here from Revain, to lubricate the entire sheath on each spark plug wire and I also lubricated the inner sheath entry of the sheath thermal shield. Even after that, it was still difficult to attach the boot heat protector to each spark plug cable boot. I'll admit it's a little pricey, but it's worth it because if you've had the experience of burning and melting a spark plug boot or rubber wire insulation to try to figure out what's wrong with your car, you might be chasing your own tail . Also, water and moisture will seep into each shoe or into the wire itself, leaving you stuck in your car on foggy days, rainy days or in the summer heat.
