I just received the Engine and Trans cables and I can speak to the quality:
- Wires are KnuKonceptz which have a 4.5 rating on Amazon with over 800 reviews.
- Have a little extra length which is perfect for engine movement. Even though I'm running Drift Freaq mounts and my motor doesn't move at all lol
- Have a light translucent black shielding that makes it a perfect dress up piece, better then the crappy stock ground cables.
- Cheaper than any quality grounding cables you'll get off Amazon or your local store. Unless your looking to make 25 ft of these things which I was not. I already have enough extra of everything.
- Ends appear to be crimped and covered in heat shrink. Terminals appear to be quality also as I can't find the standard made in china markers you get on autozone crap.
- Also the terminals are perfectly sized for mounting. No generic 1 size fits all stuff you get online.
- A true tailored product.
