 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 this hood from our friends at Treasure Coast Miata. They made a street version with headlight cutouts, as well as the race version to deleted headlights. 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.
