2011-2013 Mustang GT/BOSS Cooling Head Mod by MMR, eliminate the #8 cylinder failure

[Modular Racing]

We have seen failures on both stock and modified so this is cheap insurance to be safe.

I've heard of failures on the coyote motor but nothing with the roadrunner motor. But I agree in the fact that its cheap insurance.

cooling mod installation

I just installed the cooling mod on my 2011 mustang gt automatic .I took off the intake manifold and could not tap or pry out freeze out plugs ithey reguire a lot more force to get them to flip so you can grab them .put I did find a easy way to knock them out I used a 18 inch flat screwdriver from under the car you have access to both plugs along side the transmission in the transmission tunnel and you can guickly and easily hit the plugs so they pivot you still have to have the intake off.so you can pry them out once there pivoted. I wish I new I could do it this way before I wasted 2 hours trying everything to pivot them from the top witch Is a waste off time besides the very uncomfortable positions you have to be in . If you do it the way just explained it very easy good luck.

Is this a reasonable mod for a roadrunner motor?

This. I've heard of no #8 failures on a Roadrunner.

I have been pounding on my car for the last 18k miles and this was one of my first mods. I truly think it is worth it. It gives me a peace of mind.

and I thought all Coyote #8 failures were solved with the discovery of a factory Ford tuning issue.

Shaun @ AED exposed the problem months ago.

Still think it isn't a bad price for piece of mind.
