When running a larger intake system, such as our own, routing the factory coolant hose under the system may not be possible on some vehicles, or may fit snugly on others. We've redesigned the hose as a plug and play upgrade that neatly runs under the intake for a clean install with minimal stress on the part.. There are multiple factory coolant hoses. CI100052-D (Version 1) replaces the factory hose which is held on by a crimp clamp which must be cut. CI100053-A (Version 2) replaces the factory hose which is held on by a spring clamp.
