Apex'i
The GT Radiator Cap is a high performance replacement cap designed to provide 1.3 Kg/cm3 of pressure. This allows for higher cooling system pressures which raise the boiling point of the coolant, creating greater cooling efficiency. Available in two types for fitment on a wide variety of applications.
Universal Application
Blitz
Blitz Radiator Caps are designed to withstand extreme heat conditions and engineered to hold more pressure than those of stock applications. Blitz Radiator Caps are constructed of full stainless steel and utilizes a urethane seal.
Universal Application
Buddy Club
Higher pressures inside of the cooling system helps the coolant flow better and also increases the coolant's heat absorbing qualities. The Buddy Club Racing Spec Radiator Caps have pressure capacities of 1.3 x 100kpa (1.3kg/cm2), in comparison to a factory cap that has a pressure rating of only 0.9kg/cm2. This means that the coolants boiling point can be raised by using the Buddy Club Racing Spec Radiator cap. Advantages are of course found on demanding conditions such as circuit racing. The radiator caps are available in two types; Type A and Type B
Universal Application
GReddy
GReddy high-pressure radiator caps are OEM style caps that directly replace the factory cap. Not only does the metal GReddy badge on the cap dress up your engine compartment but the 1.3kg/cm2 (18.5psi) pressure rating increases the performance of your radiator. Two types are available to fit most Japanese vehicles.
Universal Application
Spoon Sports
A radiator cap functions to increase the pressure inside the radiator so that even if the water temperature exceeds 100C, boiling will be avoided. Stock Honda radiator caps are rated at 1.1BAR. The Spoon radiator cap increases the pressure to 1.35BAR, thereby improving cooling performance. Available in F-Type or D-Type.
All Honda/Acura Vehicles
J's Racing
In order to get raise the effciency of the cooling system, a high pressure radiator cap is the most inexpensive to do it. J's Racing offer high pressure radiator cap at 1.3kg and cooling efficency will be improved by 22% or higher. Type 1 or Type 2 available. Please call for pricing.
All Honda/Acura Vehicles
Skunk2
The Skunk2 Radiator Cap functions to increase the pressure inside the radiator allowing the coolant's boiling point to increase. Improves overall cooling performance and boiling can be avoided. A great item that truly works.
