I just have a couple bolt-ons, like theC/L CAI/brenspeed tune, steeda pullys, 4:10 gears, and Mac axle-backs. An acquaintance at work saids the cooler the engine the more horsepower I could obtain. He recommended the 32-degrees cold spark plugs. Also mention about something called ice that you drop in your radiator? Anyone?

Cooler spark plugs won't help you. They are primarily used in applictions where high combustion pressures cause the spark plug to act as a glow plug and pre-ignite the fuel charge. There's no performance advantage to them...

And as for this thing they call Ice... It's your typical average run of the mill Ice cube's, like you get from your freezer. Most guys Ice their intake manifold tho, and not their radiator unless your talking about John Force level racing teams where .005 seconds can mean the difference between a win and a loss.

The colder plugs are mainly for forced induction aplications and ice is used alot for forced induction coolers. In a radiator it melts way to fast to effectivly cool the motor for more then a minute or 2.

I believe the OP is referring to a radiator additive made by Royal Purple, it`s purpose is to to improve the heat transfer ability of the coolant. "Wetter Water" is another brand, they do work to lower coolant temps,whether there`s any HP improvement is debatable.

Yes you are correct just couldn't think of the name at the time.

Those additives like that also only matter if you are not running anti-freeze, so keep that in mind before wasting money on them...
