The M7 Speed 100% fiber reinforced 4-ply silicone Intercooler connector boots work great with OE or aftermarket intercoolers. These connectors are longer and a bit thicker than other aftermarket connector boots to ensure a better seal between the intercooler core and the inlet/ outlet horns. The added thickness gives extra strength to prevent failure during high boost operation. The M7 Intercooler Boots feature a tighter fit around the intercooler as well as the OEM intercooler horns. These are a must have for modified and high boost engine builds. Or simply replace your old, heat damaged and power robbing leaky intercooler boots with a set of brand new set of M7 Speed 100% silicone boots at a fraction of the cost od OE replacements. Available in Black Red, Green or Blue for a little added under hood WOW ! Easy to install. No special tools or skills needed.
