Let customers speak for us
from 308 reviewsQuality wires, great price point plug-in play easy to install recommend to any car enthusiast looking to update their crusty wires

Happy with the outcome of it installed! Great product. Great costumer service after I reached out on a concern about the product.

Product is as advertised. Can't beat the price or speed of shipping.
They give amazing customer service, also good quality products, I’d recommend to anyone

Factory pins were really on there well so I only used the outside connectors and guides. The pins slid into these connectors with ease, the guides went in just right and the assembled connector snapped perfectly onto the ignition coils.
Product appears to be well designed and solid.

Always good to have shipping insurance for those unexpected moments
Good quality product everything fit where it needed to

Absolutely awesome product. Fitment is good, finish is sexy, showing the machining lines, and it’s just beefy. You’ll love it, just buy it. 2001 Audi TT Quattro 225hp AMU, non VVT

Exactly what I was looking for!! Amazing quality and fast shipping

Although my part was just an o2 spacer it was well made, arrived quickly, and I liked it’s packaging

Got this harness/sub harness and shipping was quick. Looks great quality and labeled for easy install! Customer service was a great help with all the questions I had.
Note:-- this harness has already bypassed the vtec pressure switch so it has no plug for it! I had to do some research to find out but don't worry if you see no plug

Very high quality harness, very well labeled! Had a few difficulties installing, but after contacting customer he quickly walked me through every step and had it fixed in no time. Also the "customer service" was the owner contacting me himself! That should speak for itself! Will definitely be a long time customer.

This kit is a budget kit on the market, but it is still high quality! Don't over pay to IE for the same thing. The valve cover fitting needed to hit with some sand paper to fit properly and tight. Overall happy with the parts.
Great customer service
