Karlyn/STI Karlyn Spark Plug Wire Set 491w/Loom

Looks exactly like the OEM one in our '97 Z3 1.9, and it was only about a 20 minute install. The wires are all numbered for easy installation, too. If you already have the wire loom in your car, you can save yourself a lot of money by just reusing the two plastic guides and running new wires through them. The guides are a big part of the price.We changed ours out for the car's 100k mile service, and the difference in low end power is amazing. The car was chugging from a stop on hills or with the AC on, but it's running nice and smooth again now.

Took me about 15 minutes to put the new one on the car.

Perfect fit, and no problems with this set. All length were exact to include the 120 degree elbow at the coil pack end. I think this as close to OEM that you can get! Only took 10 minutes to switch out the wires.
