Installed these LLannder spark plug wires on my LS1 and the performance is noticeably better. The 10mm thickness feels sturdy, and they fit perfectly. Just wish the shipping was a bit faster, but definitely worth the wait!

One wire didn't work right
I was excited to get this spark plug wire set for my Chevy LS3, but one of the wires had a defect and didn't make proper contact. I reached out to customer service, so I’m hoping they can send me a replacement. Otherwise, they look great!

Good set but slight confusion with compatibility
I bought these for my LS6 engine, and they work as expected. However, I had to double-check the compatibility since I wasn’t sure if they fit my model. The quality seems high, but the installation instructions weren’t super clear. Still, it did the job!

Excellent performance boost!
These 10mm spark plug wires from LLannder are amazing! My V8 engine runs much smoother and accelerates better after the install. They seem very durable, and I appreciate the quality. Would definitely buy again.
