Doing a K24 swap in an NA? The K20 clears the stock hood, but a K24 is about a half inch too tall. If you don't want to cut your hood, we recommend our modified K24 valve cover. All NB hoods clear both the K20 and K24 without issue.
Note: The engine mounts included in this kit are performance-oriented and designed to limit engine movement. The additional stiffness may result in a slight increase in NVH (noise, vibration, harshness), but can withstand years of hard driving as a result.
