Default Karlyn/STI Spark Plug Wires?

Anyone using Karlyn/STI spark plug wires? They look to be 8mm based on the info on their web site, but was hoping to get some feedback from a forum member before ordering.

Karlyn/STI Spark Plug Ignition Wire Sets

Any feedback would be great. Currently have Napa Premium 7mm on the Disco and need to replace soon. Thanks.

Pro tip --- Try using the search function. This topic has been covered here ad nauseam.

That said, STI wires are great. Consistenly great, according to others here and me.

My first set served my truck perfectly for 10+ years and 72,000+ miles. I replaced them proactively only because I was doing the same with the spark plugs and I picked up a set of STI wires from RockAuto for <$12.

I wasn't suggesting that the Rock Auto price I paid was common. Nor did Best4x4. Rock Auto apparently has closeout prices very often.

That said, the Amazon price is still affordable. Plus I just Googled "STI 721" and found them at CarID for $27.67 before shipping.

Wow that certainly beats the $70 price at BPU!

Sorry for resurrecting an old thread, but I just noticed something on the Amazon page (well after placing an order for a set of the Karlyn/STI wires) that they require some specific coil? So, they aren't compatible with the Bosch ignition coils (ERR6045)?
