Just bear in mind cutting/stripping spark plug leads isn't exactly the same as other wires. There's other things in there, so if you know that you'll be fine. Personally, I have no problem having Magnecor make mine. The total cost of the custom wires is less than the "correct" crimping tool so it's worth it to me. That and I think your turbo KL won't be quite as sensitive as my built 13B when it comes to the ignition. It's VERY important to still get a full, consistent spark when the engine is turning at speeds upwards of 9,000 RPM...
