Product Details

The MSD 3407 Shrink Sleeve is a heat-activated protective sleeving kit designed to seal and protect spark plug wire connections and other electrical connections throughout your vehicle. Each sleeve slides over a spark plug boot or terminal connection, and when heat is applied, it shrinks tightly around the wire for a secure, weatherproof fit.

Key Features:

  • Heat-shrink design forms a tight, protective seal around connections when heat is applied
  • Will not split and is engineered to withstand high underhood temperatures
  • Versatile ? suitable for spark plug wire connections as well as other electrical connections throughout the vehicle
  • Black in color for a clean, professional appearance
  • Includes 18 pieces, each approximately 2 inches in length
  • Legal for use on emissions-controlled, non-emissions-controlled, and racing-only vehicles

The MSD 3407 Shrink Sleeve kit is an essential accessory for anyone building or servicing spark plug wire sets, offering a simple and reliable way to protect critical ignition connections from heat, moisture, and abrasion.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Best price I can find on my item and fast shipping. Thinking about becoming a member to order all my parts for my racing team.

Had by far the cheapest place on the internet for the part I was looking for! Shipping was extremely fast as well! A++

All pieces ordered were shipped promptly and arrived in very great shape. I will be ordering from this site again.

Good prices. Good communication.
