It doesn't matter what the manufacturer is, if it's not impact grade it's going to snap. Believe me, I've pulled a lot of heads off of these cars. The first couple took 3-4 "regular" 10mm drives to get all of the cam bolts off, the drives just kept breaking. I finally got ONE impact grade 10mm and have taken 3 engines apart (12 cam bolts) without a hiccup. All you need is an impact grade 10mm, a breaker bar, and something to keep the cam from spinning (OEM cam wrench, or the timing belt around the crank trick).

This is similar to the one I have, but the bit length is a bit shorter on mine.

There are plenty out there that will work fine. You're not going to find any of them in your local home depot or autozone though.
