Is it just me, or do those look like 3SGTE wires? And the 91/92 5SFE wires are round, and the 93+ are square.

You can find the OEM Toyota units from partznet for about that same price.

Copper plugs on a 5s are a waste in my opinion. You'll have to change them more often with no appreciable gain. A good brand of platimnum plugs and be done with it.

They're still working. I don't know that I'd say they're still "going strong". If anything this only reinforces the fact that different plugs in the 5s make little or no difference. Copper plugs gnerate a better spark, but wear out faster than platinum plugs, that's why MR2s, both turbo and NA left the factory with platinum plugs. On the turbo with the boost cranked up you might want copper plugs to generate a stronger spark. But with teh 5s... hell you could have two piece of flint in there to ignite it and would perform about the same.

Just so you know those ARE IN FACT turbo plug wires. (Atleast what's pictured)

BTW, plugs are plugs. The only reason some recommend a certain brand is by quality or price. They will not enhance or hinder power unless they are faulty in that case they will hinder. The reason why so many recommend the coppers is cause they are dirt cheap.
