After a successful DIY install of LS2 coils in my car, I figured I would document a DIY to create one of the most important parts of the install, the LS2 spark plug wires.

Special Thanks To TeamRX8 For His Advice During This Build

Requirements

• 12' of MSD ignition wire, http://www.summitracing.com/parts/MSD-34039/
• 90 degree Spark Plug Boots, http://www.summitracing.com/parts/TAY-46061/
• 45 degree Coil Boots, http://www.summitracing.com/parts/TAY-46069/
• Spark Plug Crimping Tool, http://www.summitracing.com/parts/TAY-43390/

The first thing you want to do here is get yourself familiar with the makeup of the wires. These particular wires are spiral core, so to someone unfamiliar with the wire, you may assume that the core itself is the wire's shielding.


Here is a little image to show you exactly what the wire looks like on the inside.

Step 1: Strip about a little less than 1/4" off of the wire


Step 2: Fold back the core, and place your boot contact on


Step 3: Crimp the contact against the wire


Step 4: Examine the contact to ensure quality crimp

Step 5: Grab a can of wd40, and spray the inside of the coil/plug boot


Step 6: Once sprayed, slide the end in all the way through


Step 7: Do the same for the other side


Step 8: Complete the other wires


As you can see, I used the same length for each of my wires which was 16.5". This gave me enough room and ensured that I could get a perfect connection to each plug.

Doesn't the length of the wire affect the individual resistance as well ?

when discussing foot lengths of wire yes

I remember reading somewhere in the manual that when checking the OE wires, different specs were related to the shorter ones vs the longer ones. Does making 4 equal ones make a difference ?

just tested my OEM wires .... all wires range from 2.4 - 2.6 kOhms.

I am now testing a 6' strand of the MSD wire ... reading 0.266kOhms ....

Awesome :D Looks good by the way, glad you didn't go with the multi-angle boot.

eventually you will need this too, regardless of coil/wire type

Sweet! Nice to see members do things like this on their own.

I keep forgetting to add the specialty LS2 wires to the Race Roots site, thanks for reminding me.
