Mazda stock replacement motor mounts. Great for replacing damaged or aged motor mounts without an increase in noise, vibration or harshness. We've pulled cracked ones off 8-year-old Miatas with 60,000 miles. We recommend changing these every time you have the engine out, unless you make a real habit of it.
If you're looking for stiffer mounts to prevent a high-hp engine from moving around at the expense of some noise, you might want to consider the Mazda Competition mounts.
Two needed per car, sold individually. Fits all NA and NB Miatas, including the Mazdaspeed.
