Mine was 13. I got the specs from autozone, you should just be able to take it in there and they can do this for you.
Ahhh - I just noticed your year. You don't have that coil rail in your model do you?

Tip for future referance.

99% of the time a backfire out the intake is caused by a lean condition and a backfire(Actully an afterfire) out the tailpipe is too much gas.
