Had a hard time getting other products from Amazon sellers but this is the real thing. Very top quality. Complete with all pieces and even lube. Haven't installed these yet but noticed the wires have precut ends so you don't have to strip them. Would recommend these and if needed buy them again.

Looks good! Cleaned up my engine bay real nice! No more wires that are to long or short. They all fit perfectly, Strips and crimps good with a quality stripper/crimper tool. The only CON is, it’s still a high impedance conductor, But this is expected. If you want super good quality, low impedance plug wires then you’re gonna spend closer to 200$

So this package is for when you want/need to make your own cables, meaning field cut & crimp ends. And, you need a special spark plug wire crimper, not just any crimper will work. So they are not the standard pre-crimped cables, understand that. They are nice & thick and smooth. I love the red to it matches my Dodge L6's factory head color. Only complaint is that I would have wanted strait connects/boots for the distributer end; the kit only comes with a 90deg dist option.
