I actually just put one of these in a '99 4Runner about 3 wks ago. Didn't fit the tray exactly but it's in there... was the smallest size and cca listed for that particular vehicle. About a week later we had temps down into the low 20's/ upper teens... lasted about 3 days and nights. SUV started right up each sub-freezing morning. Starts strong every time since I've had it. I'm sold. Only a 1 yr replacement on it but hell, the thing was less than $50.
