*UPDATE 2014: The battery industry has done away with in-house testing, the 475 CCA was based on in house room temperature Midtronics tester, but starting this year these ship with independent lab test spec of CCA measured at 0 degrees F for 30 seconds (which is 320 CCA for this battery). Same battery, just a much more demanding test that may or may not reflect your local conditions. How many of us live in 0 degrees? Here in San Diego average day is 70 F and the battery can make 475 CCA here. Regardless, for those who have used and depended on Westco for all their Miatas going back two decades just understand the battery and the CCA it offers hasn't changed, just the testing standards.

Westco 12V31M Miata Battery
Solid. Works like a charm. It's snug too. My battery died on me and now I can drive my miata to my buddy's place to swap my engine.
Perfect fit, good life, usually last 5-6 years, consistent quality. Kept on trickle charger in between track events.
The Westco battery is simply the perfect replacement battery for an NA Miata. The Westco I replaced lasted about 8 years, parked outside thru 8 cold New Jersey winters. The Westco fits perfectly, has the terminals on the exact right locations for the stock wiring, and mates perfectly with the stock battery tie down. It also has the little ports for the vent tubes to route any gasses out of your trunk. It arrived in perfect condition, with a strong initial charge. This is the only battery I'll ever buy for an NA or NB Miata.
This is the one you want for a Miata. They last five or six years. They fit perfectly. They are maintenance free.
