Check the tool racks at your auto parts store. A good choice will have a good length and an extension that can be attached at different angles and some adapters. Breaker bars work in some cases but I find todays engine bays too tight,no clearance for a breaker bar. Especially imports. One that I have comes to mind is an Ampro. Reasonably priced. Although sometimes none of them seems to fit and ya gotta get creative.
