Best Spark plugs to use?? IC question

[samuelcb409]

Had al104s but got a full size IC done and 3.0 pulley was wondering if switching plugs which would be best to use??

Also when filling IC should I use all water or coolant? Just curious cause I was told to use both but making sure

Try the same plugs.

See how they burn.

I've added boost, then an intercooler and more boost, and I find AL104's and TR6's still too cold.

Coolant in the system, otherwise corrosion will take place.

You can run as little as thirty percent coolant and still maintain that.

If you're using Dexcool in the engine cooling system I'd suggest a premium coolant like Prestone in the intercooler system to make it easier to identify which cooling system is leaking.

Your in Texas so freezing isn't as big a problem but I would run some coolant for corrosion protection.

So al103 aren't a good idea or would something else be better

 

[matt5112]

try them

At what gap should I use them at

Always use the hottest plugs you can get away with.
