## Customer Reviews

### ⭐⭐⭐⭐⭐ Exact Match & Quality with Genuine Mercedes
*by B***L on February 26, 2017*

Purchased from seller "German Auto Supply" and they are very helpful identifying country of origin for these 16 wires. The K wires are made in Spain & the G, H, L wires are made in Germany so I am perfectly with both countries.The wires are so new & STRAIGHT so when you plug into ignition coil, it may have slip off easily from the coil repeatedly. NO worries, simply let it sit overnight so the wires are used to the new bent angle and the next morning it's SUPER SUPER tight with the coil. I also use marker to write cylinder numbers into these 16 wires so it's easy for identification purpose.My M113 engine is now idling smoothly and I have no worry for the next few years.

### ⭐⭐⭐⭐⭐ Exactly what I needed for my Mercedes 1999 G500!  (M113 V-8)
*by J***D on September 5, 2017*

Exact fit for my 1999 G500! Outstanding product quality as it is genuine Bosch manufactured. New in the box and exactly as described. My M113 V8 engine runs perfectly now. I would purchase again if needed, but hopefully I will be good for another 100K miles. Thank you for your quick shipping and great price!

### ⭐⭐⭐⭐ 2004 Mercedes E55 AMG
*by J***C on September 17, 2012*

Installed these on my 2004 E55 AMG w/100K miles, no issues so far. They are the same as OEM ones.Spark plug wires rarely go bad - if you have a multimeter you can take out the old wires and test the resistance, if they are still good you don't need to change them.On the E55, the wires are directly above the hot exhaust manifold so the insulation jackets tend to degrade over time (mine were still good when I pulled them out however. I'm keeping the old ones as spares)Don't forget an offset 17mm open end wrench to pull these out of your Mercedes it will be a lifesaver.
