Oil Catch Cans and Air-Oil Separators

Oil catch cans and air-oil separators trap crankcase blow-by oil vapors before they contaminate the intake tract, throttle body, supercharger, or intercooler. Direct-injection HEMI, Hellcat, Trackhawk, RAM TRX, Camaro, Corvette, CTS-V, and EcoBoost engines carbon-foul intake valves faster than port-injection engines, so a catch can is one of the highest-value engine upgrades on these platforms.

Popular Catch Can Brands

Billet Technology, MightyMouse Solutions, JLT Performance, RX Performance, UPR Products, Corsa Performance, and Elite Engineering. Confirm the exact vehicle and engine before ordering because catch cans are engineered per platform (Hellcat vs Trackhawk vs Durango vs TRX use different sizes and mounts).

Supercharger Pulleys and Boost Support

Supercharger pulley upgrades change blower speed and raise boost pressure on Hellcat, Trackhawk, Demon, Redeye, Durango Hellcat, RAM TRX, and Whipple-supercharged builds. Smaller drive pulleys raise boost, larger idler pulleys hold belt tension, and hub kits allow easy pulley swaps without pressing the pulley on and off the supercharger snout.

Popular Pulley Brands

ZPE GripTec (Hellcat, Trackhawk, TRX drive pulleys and hub kits), AAD (adjustable idler pulleys and IHI tensioner pulleys), Metco Motorsports (Cobra Jet and Predator applications), and Whipple (Whipple supercharger drive pulleys). Any pulley change requires an ECU tune to keep the engine safe at higher boost.

Cooling, Thermostats, and Radiators

Engine cooling upgrades support reliability on hard-driven street cars, tow rigs, track builds, and forced-induction applications. Lower-temperature thermostats open sooner, aluminum radiators shed more heat, larger fan shrouds move more air, expansion tanks replace failure-prone plastic OE parts, and coolant bypass kits improve flow through the block.

Popular Cooling Brands

Mishimoto (thermostats, radiators, expansion tanks, coolant hoses), CSF (Trackhawk, TRX, and BMW radiators), Granatelli Motor Sports (HEMI thermostats), Billet Technology (thermostat housings and coolant caps), and Cordes Performance (engine bay ice tanks for Trackhawk and Durango Hellcat).

Throttle Bodies, Intake Manifolds, and Spacers

Larger throttle bodies and higher-flowing intake manifolds support forced-induction and naturally aspirated horsepower goals. Phenolic and aluminum intake spacers reduce heat transfer from the cylinder head to the intake plenum, keeping incoming charge air cooler.

Throttle bodies must match the intake manifold flange, TPS connector, and drive-by-wire calibration. Do not order a larger throttle body without confirming ECU tuning support.

Ignition, Sensors, and Fuel Delivery

Ignition coils, spark plugs, glow plugs, and coil-on-plug hardware for HEMI, Hellcat, LS, LT, Coyote, EcoBoost, K-Series, and 2JZ platforms. Sensors include mass airflow sensors, oxygen sensors, coolant temperature sensors, and crank and cam position sensors. Fuel delivery covers OEM-replacement pumps, flex fuel kits, distribution blocks, and high-flow return-style fuel systems for boosted applications.

Engine Bay Dress-Up and Billet Accessories

Billet cap covers (oil, coolant, brake fluid, power steering, washer fluid, A/C port), fuse box covers, hood prop covers, carbon fiber radiator covers, carbon fiber fan shrouds, carbon fiber engine covers, and supercharger badges. Popular on Hellcat, Trackhawk, Durango Hellcat, RAM TRX, and Wrangler show builds.

Popular Dress-Up Brands

Billet Technology (machined billet caps and covers), Black Ops Auto Works (carbon fiber engine bay panels for Grand Cherokee, Trackhawk, Durango, and Challenger), Exotic Innovations (carbon fiber engine covers), and Rebadge Design and Graphics (supercharger and engine bay badges).

Rotating Assembly, Heads, and Internals

For built engines, Black Ops Auto Works stocks connecting rods, rod bolt kits, bearings, pistons, camshafts, cam gears, cam seals, cylinder heads, gaskets, and head studs. These are platform-specific and require professional machining and assembly.

How to Choose the Correct Engine Part

• Confirm the exact year, make, model, and trim (Hellcat, Redeye, Demon, Scat Pack, R/T, SRT, TRX, Trackhawk, Rubicon, and so on)
• Verify the engine displacement (5.7L HEMI, 6.1L HEMI, 6.2L supercharged HEMI, 6.4L 392, 3.6L Pentastar, 3.0L Hurricane, 5.3L LM, 6.2L LT4, 5.0L Coyote, 2.7L or 3.5L EcoBoost, K20, K24, 2JZ)
• Confirm induction type (naturally aspirated, supercharged, turbocharged) because catch cans and cooling parts are engineered per platform
• Verify PCV routing and fitting size on catch cans (front bank vs rear bank vs dual can setups)
• Confirm belt rib count, hub style, and belt length when ordering supercharger pulleys
• Match thermostat opening temperature to your driving profile (160 degree, 170 degree, 180 degree, or OEM temp)
• Confirm radiator inlet and outlet positions and mounting style before ordering an aluminum upgrade
• Verify sensor connector type and signal calibration for ignition, MAF, and O2 upgrades
• Plan for ECU tuning after any supercharger pulley, throttle body, header, or forced-induction upgrade
• Order supporting hardware (gaskets, hoses, hardware kits, tuning, alignment) alongside major engine upgrades

Common Questions

Do I need an oil catch can on a modern engine?

Direct-injection engines (HEMI 5.7L Eagle, Hellcat 6.2L supercharged, Trackhawk, TRX, RAM 1500 5.7L eTorque, LT1, LT4, Coyote, EcoBoost, and modern turbocharged fours) benefit from a catch can because they carbon-foul intake valves faster than port-injected engines. A catch can traps oil vapor before it reaches the intake, keeping the intake tract, throttle body, supercharger, and valves cleaner.

Does a supercharger pulley change require a tune?

Yes. Any change to the supercharger drive pulley or overdrive pulley on a Hellcat, Trackhawk, Demon, Redeye, TRX, or Whipple-supercharged application changes boost pressure and requires an ECU tune to adjust air-fuel ratio, ignition timing, and knock protection. Do not run a pulley change on a factory tune.

What thermostat temperature should I run?

Factory thermostats on HEMI, Hellcat, and Trackhawk applications open around 203 degrees. Performance thermostats (Mishimoto, Granatelli, MAP) open at 170 to 180 degrees, letting the engine reach operating temperature but keeping coolant temps lower on hard driving. Match the thermostat to your ECU tune, some tunes require a specific thermostat opening temperature.

Are aluminum radiators required for stock horsepower?

No, a stock radiator is sufficient for a stock engine driven under normal conditions. Aluminum performance radiators become useful on tuned and boosted applications, tow rigs, hot climates, track days, and vehicles with plastic OE radiators that have started to fail with age. CSF, Mishimoto, and Ron Davis radiators are common upgrades on Trackhawk, TRX, and Hellcat platforms.

Can I install a larger throttle body without tuning?

Not safely. Larger throttle bodies change airflow calibration and idle air control behavior. On drive-by-wire vehicles the ECU must be recalibrated for the new throttle body position sensor scaling. Combine throttle body upgrades with a full tune covering intake, throttle body, and any other bolt-ons.

What is the difference between a catch can and an oil separator?

The terms are often used interchangeably, but a true air-oil separator is engineered with internal baffling and coalescing media that separates oil aerosol from air and returns oil to the sump or to a drain bottle. A simple catch can is a hollow container that condenses oil vapor into a drain reservoir. Both serve the same purpose, but separators are more effective on supercharged and high-blow-by engines.

Do headers require a tune?

Long-tube headers and high-flow catalytic converters typically require a tune to adjust for the changes in exhaust flow, oxygen sensor placement, and downstream O2 sensor readings. Shorty headers and mid-length headers usually do not require a tune on naturally aspirated engines but always confirm with the manufacturer.

What is a coolant bypass kit?

A coolant bypass kit reroutes coolant around a bypass port on the block or head, improving flow to the cylinder head and reducing coolant temperature under hard driving. Popular on LS, LT, and HEMI platforms where the factory bypass port limits flow at high RPM.

How often should I drain my catch can?

Under normal driving, most catch cans need draining every 3,000 to 5,000 miles. Boosted, high-mileage, or hard-driven engines may fill the can faster. Drain intervals are shorter in cold weather because more water vapor condenses out of blow-by. Check the can weekly for the first month after installation to learn the fill rate on your vehicle.

Do I need supporting mods for a smaller supercharger pulley?

Yes. A smaller supercharger drive pulley raises boost, which increases fuel demand, cylinder pressure, and heat load. Common supporting mods include an ECU tune, larger fuel injectors, higher-capacity fuel pump, upgraded intercooler heat exchanger, colder spark plugs, high-temperature engine oil, and often a catch can. Plan the full package before ordering the pulley.
