Upgrade worn factory intercooler couplers with the IAG “Stock” Top Mount Intercooler Coupler Kit. Designed as a direct replacement for factory-style top mount intercooler connections, this kit improves durability while maintaining a stock-style fit.
The couplers are constructed from heavy-duty 5-ply aramid-reinforced silicone, providing more strength than the factory 3-ply couplers while holding their shape under boost and high engine-bay temperatures. IAG also incorporates a molded clamp holder and integrated pry point into the turbo-side coupler to make installation easier in the tight space between the turbocharger and top mount intercooler.
