Q & A

What's in the Box

Cooler intake temperatures mean more power. It's just that simple. While the factory supercharger cooling system is adequate in stock configuration, it struggles to keep up with the multitude of popular modifications that not only deliver more power, but also increase the stress and strain on the engine. AFCO's Heat Exchaners will regain lost horsepower by more effectively cooling intake temperatures, creating a more dense intake charge versus stock. This is critical in controlling detonation in a supercharged application.

  • Optimized core technology for greater air flow
  • Drops inlet temps to near ambient while under boost
  • 100% Aluminum TIG-welded construction - NO EPOXY
  • Direct Fit bolt-in installation - NO cutting & NO drilling required
  • Installs with simple hand tools in approximately 30 mins.
  • Consistent Performance - keeps coolant temp stable, pass after pass

The Single Pass is great for an occasional stop on the gas, but if you are continually requiring mass amounts of power, the added cooling of the Double Pass and Fan/Shroud are your best choice.

Red Line 80204 Water Wetter Coolant Additive
                        

Red Line Water Wetter Super Coolant additive is a unique wetting agent which reduces coolant temperatures by as much as 20° F. This is a liquid coolant treatment product which is designed to be added to solutions of antifreeze and water to help improve the heat transfer properties of glycol-based antifreeze. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Improves the ability of coolant to wet heat transfer surfaces by 50%.

  • Reduces or eliminates bubbles that form on hot metal surfaces to reduce coolant temperatures by up to 20°
  • Superior heat transfer properties compared to glycol-based antifreeze
  • Compatible with new or used antifreeze (including DEX-COOL and long-life versions) to improve the heat transfer of ethylene and propylene glycol systems
  • Improves heat transfer and reduces cylinder head temperature
  • Designed for use with all modern aluminum, cast iron, copper, brass and bronze cooling systems
  • Cleans and lubricates water pump seals
  • Reduces cavitation and complexes with hard water to reduce scaling
  • Does not lower cooling system below the thermostatically-controlled temperature
  • 12 fl. oz. bottle treats 12-20 quarts

Pro-Blend 8012 Engine Cool Oil Additive, 11.5 Oz. Bottle
                        

This amazing oil additive can reduce oil temps by up to 57° and coolant temperature up to 7°. By reducing friction in an engine you also reduce the operating temperature. This has proven to double the engine life and also increase fuel mileage. Engine cool is compatible with regular and synthetic oils and unlike other "snake oils" contains no teflon, moly or silicone.

Add one bottle per oil change. 

11-1/2" oz bottle.

Pro-Blend 4032 40-Below Engine Coolant Additive, 30 Oz.
                        

Reduces coolant temps up to 40° F. Prevents coolant temperature from rising excessively under extreme racing conditions. 30 oz. Use a 80% water and 20% Pro-Blend 40 Below mix.

NOTE: Do NOT use with propylene glycol antifreeze, stop leak, or block sealer. Can be used with distilled water and ethylene glycol antifreeze.
