For users of TTA spark plug heat shields - arcing problem

[QuickWE4]

Well, I've got those TTA spark plug heat shields on my TR.

I noticed that the plug for the #2 cylinder is arcing from the spark plug heat shield to the exhaust manifold heat shield (comes pretty close to the manifold shield). Are the exhaust manifolds different on a TTA or do they lack the heat shields?

Anybody else run into a problem using these on a TR? Could this have damaged anything (coil, etc)?

I guess I'll have to take them off Not that it's a big deal, I just think they look trick.

The exhaust manifolds are very different on a TTA. I don't use them on my TTA just the MSD wires. And arcing out will ruin your wire, coil, or module eventually.
