Flex Technologies CAC40P-300X6 Cold Side Charge Air Boot – 3 in x 6 in Polyester

Quality replacement cold side charge air connector for heavy duty diesel engines. The Flex Technologies CAC40P-300X6 is a convoluted silicone charge air hose with stainless steel retention rings, 3.000 in inside diameter by 6.000 in long. Polyester reinforcement rates it to 350°F, which suits the cold side between the charge air cooler outlet and the intake manifold.

Signs You Need a New Charge Air Boot

• Loss of boost and power, with poor throttle response under load
• Audible whistle or hiss under acceleration
• Boost pressure or charge air system fault codes
• Visible cracking, splitting or soft swollen spots in the silicone
• Oily film weeping at the clamp joints
• Boot blown completely off its tube

Specifications

Applications

This charge air boot is selected by size rather than by vehicle, and fits:

• Cold side charge air piping with a 3 in outside diameter tube
• A 6 in gap between tube ends
• Heavy duty on-highway and vocational diesel engines

Measure the outside diameter of the tube it clamps to and the gap to be spanned before ordering. This is the COLD SIDE boot, rated 350°F and colored blue — it must NOT be fitted to the hot side at the turbo outlet, where temperatures exceed its rating and it will soften and blow off under boost. The matching 3 in x 6 in hot side boot is aramid reinforced and rated 500°F. Use SAE compliant clamps.
