Radium Engineering Questions Answered

Radium Engineering makes precision-machined fuel system and engine ancillary components for street and motorsport use, including oil catch can kits, fuel cells, fuel surge tanks, fuel pressure regulators, fuel rails, and coolant reservoirs. Their products are designed and manufactured in the USA and are commonly used in track, time attack, and high-performance street builds.
An oil catch can installs in the crankcase ventilation system between the engine's PCV valve and intake manifold, trapping oil vapor and combustion blow-by before it re-enters the intake. This keeps oil residue out of the intake tract and intercooler, which is especially important on turbocharged engines where blow-by is more significant and oil buildup can reduce power over time.
A fuel surge tank is a small secondary fuel reservoir that sits between the main fuel tank and the fuel system, ensuring a constant fuel supply to the engine during hard cornering, acceleration, or braking where fuel can slosh away from the factory pickup in the main tank. They are commonly used on high-power turbocharged builds and track cars where fuel starvation under sustained high-g loads is a real concern.
Radium Engineering fuel cells are purpose-built competition fuel tanks designed to replace the factory fuel tank on race and track cars. They use a baffled internal design to prevent fuel starvation during hard cornering and are available in various sizes including a spare tire well fitment option that replaces the spare tire in the trunk for a clean, low-profile installation.
Radium Engineering's single catch can kit intercepts one side of the crankcase ventilation system, typically the PCV side. The dual catch can kit intercepts both the PCV and the valve cover breather sides, providing more complete blow-by capture on both ends of the system. The dual kit is more effective on turbocharged engines that produce more blow-by under boost.
Yes, Radium Engineering designs and manufactures their products in the USA, which is a key part of the brand's reputation for precision machining quality and consistent tolerances across their catch can, fuel cell, and surge tank lineups.
Radium Engineering makes vehicle-specific catch can kits for a wide range of performance and enthusiast vehicles including the Subaru WRX and STI, Honda Civic Type R FK8, Ford Focus ST, Mitsubishi Evo X, BMW E46 M3, and many more.

Choosing the Right Radium Engineering Product

Catch Cans: Street and Mild Track Builds

If you drive a turbocharged or high-performance naturally aspirated vehicle on the street or occasional track days, a Radium catch can kit is one of the most practical preventive maintenance upgrades available. It installs directly into your existing PCV system using vehicle-specific brackets and fittings, requires no fuel system modification, and keeps oil vapor out of your intake for cleaner combustion over time.

Surge Tanks: High-Power Builds and Track Cars

If you're running a high-power turbocharged setup or doing sustained high-g driving on track, a fuel surge tank is a critical upgrade to prevent fuel starvation. Radium surge tanks are available in universal and vehicle-specific configurations and pair with most aftermarket fuel pump setups.

Fuel Cells: Dedicated Race and Track Builds

Radium fuel cells are for dedicated track and race cars where the factory fuel tank is being removed entirely. Their spare tire well fuel cell is a popular option for time attack and track day builds since it fits directly into the spare tire recess for a clean, low trunk floor installation without custom fabrication.
