Gain a guaranteed increase in horsepower and torque with a K&N cold air intake system featuring a mandrel-bent aluminum intake tube. Each system is paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical filter design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield or air box helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes.

Excellent wire!
Size: 2 Colors each 10FT, Style: 10AWG
This wire is very soft and flexible. Many strands and tinned nicely. A perfect upgrade for my power wheel wires that keep melting. These have been running for months in exterior environment without any issues.

Perfect for what I needed.
Size: 2 Colors each 10FT, Style: 10AWG
I used this wire for the umbilical cord from my truck to my slide in camper. The flexibility of this wire makes it much easier handle and route in between the cab and bed. I do have it enclosed in a flexible cover.
