 Frequently Asked Questions

Why buy a radiator cap?
With a high horsepower motor that sees the track often, you'll need a high-pressure radiator cap. With a higher pressure rating it raises the boiling point of the coolant

How do you install a radiator cap?
Radiator caps are installed in seconds by removing your factory cap and replacing it with a high-pressure unit.
