Frequently Asked Questions
What coolant should I use in the supercharger cooling circuit?Use the coolant type specified by the OEM for the supercharger intercooler cooling circuit. Typically this is a 50/50 premix of OEM-specified coolant and distilled water. Refer to the factory service manual.
Does the supercharger coolant cap maintain OEM pressure rating?The 3001114 is designed to match OEM thread engagement and sealing. It maintains the same sealing characteristics as the factory plastic cap.

What finish options are available?The 3001114 is available in satin and multiple anodized color options. Select from the product page variants.
