It is suitable for 2.0L (K20) and 2.4L (K24) engine displacements and holds up in boosted applications with higher oil temperatures. Installation is straightforward, with an estimated DIY time of 60-90 minutes. No additional hardware is required, as it reuses OEM bolts and seals. Crucially, this tensioner requires zero cutting, tapping, or tuning, making it a direct swap. It is compatible with turbo and supercharged K-series applications. This tensioner directly replaces previous revisions, including part number 13450-RAA-A01. It is designed for a wide range of Honda and Acura vehicles from 2002 to 2011, including specific models like the Acura RSX, TSX, CSX Type-S, Honda Accord, Civic Si, CR-V, and Element.
