The Chilly Exhaust Heat Shield is the most effective heat shield on the market. The innovative three piece design consists of a top shield attached to 2 rails with rivets and spacers. This reduces the contact area and slows down heat transfer. They have incorporated a patented, insulated reflective blanket on the underside of the shield to reduce radiant heat transfer. The included stainless steel clamp makes it simple to install.

We highly recommend a heat shield if you run soft luggage without hard racks.

FEATURES:

• Solid Top Shield - The logo is laser etched and there are no cutouts on the top shield. This prevents radiant heat from passing straight through to your luggage.
• Side Rails - By isolating these with spacers the heat conductive surface area to the top shield is reduced and slows down heat transfer.
• Radiant Heat Shielding - The reflective insulated blanket on the bottom of the shield is the real hero. This patented material won't be found anywhere else in the motorcycle industry. 
• Stainless Steel Clamp - Slots have been provided in the side rails to make installing as easy as it gets.
• Brushed Aluminum - Lightweight and looks nice.

DIMENSIONS:

• Length 7.5" (190mm) x Width 3.5" (76mm) x Height 1" (25mm)
• Clamp fits any exhaust 3.5" - 5.5" (89mm - 149mm)

The Dynojet Auto Tune kit is an "add on" accessory that can be used with any of our Power Commander V’s. It connects to the PCV with a single cable and requires only a ground and +12 volt connection to be made to install. If your exhaust does not already have one, a "weld in" O2 sensor bung is included.

Once installed, the Auto Tune kit monitors the fuel mixture (by installing the included Wide Band O2 sensor in the exhaust). It then sends this information to the Power Commander V and automatically corrects it while you ride. Each map that we offer has preset Air/Fuel ratio values included that we find to be the best overall settings. This lets you simply plug in the unit and let it do the work.

POD-300 Digital Display

Simply connect the included CAN cable and you’re ready to go; there’s no need to tap power or deal with other messy connections.

We recommend that you put a dab of silicone or something to hold the nuts in so they don't jump ship like the other ones did.
