I’m not surprised he has gotten an early start. Start showing explicit programs in the early evening with topless women who’s breasts are covered by an opaque bar and what do you expect? And forget that, there are innuendos in even supposedly children friendly shows like Friends of couples sleeping together and how can you possibly NOT expect a child to get curious and for his lust to be whetted? Of course he’s going to want more, and the unadultrated uncensored truth too.
I think many Muslim kids already realize that looking at porn is wrong but correct me if I’m wrong, it’s like an addiction and you end up looking at it even if you don’t want to. I think probably the best thing you can do for the kid is tell him ways to avoid it. There are many very good tips on Islamic websites and I’m going to post some links. I hope this helps. I would not install any filters, he needs to do the prevention stuff himself and he’s not a baby anymore to have right and wrong forcefed to him. My female friends had access to sexually explicit material when we were 11 and we were already daring each other to strip. And in highschool and university, sex is pathetically easily available so it’s good that he learns how to avoid things himself.

Tip #1: Know what is Halal and what’s not
Tip #2: Remember your accountability to Allah
Tip #3: Become conscious of the Haram
Tip #4: If feeling overwhelmed, remember Allah
Tip #5: Seek refuge in Allah from Shaytan
Tip #6: Get up and leave
Tip #7: Avoid those involved in pornography
Tip #8: Stay away from places where it’s found
Tip #9: Surf or watch T.V. when others are around
Tip #10: Remember your example
If you have younger brothers and sisters, think of the bad example you’re setting for them. What message will they get if they barge into your room and catch you watching Baywatch or flipping through Playboy.
Tip #11: For brothers-remember your mom and sister
Disgusting right? Exactly. No one in his right mind would look at his mom or sister the way many of us look at the Baywatch babes or the girls on the internet or in magazines. Remember mom and your sister, and that should sicken you enough to stop, Insha Allah.
Tip #12: Have someone watch over you
If you really feel you’re becoming addicted (see http://www.soundvision.com) to this kind of material, try to watch TV, surf the internet with someone else. You don’t have to tell them why you’re doing this, but this method can perhaps keep you in check and help you avoid looking at pornography or other similar material. After all, Shaytan tempts us most easily when we’re alone. Sitting in the company of a family member or good Muslim friend will Insha Allah, help.
Tip #13: Fast
The Prophet (peace and blessings be upon him) advised us to fast to cool passions. This should be a method we use to handle the desire aroused by pornography and similar material.
Tip #14: Tauba: Return to Allah
If you do end up watching the bad stuff, repent to Allah. Seek His forgiveness, reaffirm your faith in Him, and do good deed to compensate for that sin. He is All-Forgiven as long as you are sincere.
Tip #15: Repent Again and Fine Yourself
If you lapse, do tauba again. Allah is All-Forgiving as long as we mean it. But then you need to discipline yourself by promising to yourself that if I did it again, I will pay this much in charity or fast for a day.
Some parents might think the only way to stop the infiltration of pornography into the minds of their children is by simply cutting off the source of the material. They would consider, for instance, not even installing or disconnecting the internet from the home.
But while this may solve the problem temporarily, it does not teach young Muslims how to deal with this material when they see it everywhere else: on television, billboards on the street, or magazines, for instance.

Sorry for the long reply but the links are very usefu. Good luck. I think he must be masturbating as well so talk to him about that too.
