Engine Parts

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliability hardware protect expensive engine components from preventable damage caused by oil vapor ingestion and thermal stress.

Popular Upgrades

Best-selling products include Billet Technology and MightyMouse catch cans for the Hellcat, Trackhawk, Ram TRX, Camaro, and Corvette PCV systems, ZPE GripTec supercharger pulleys and idler upgrade kits that reduce supercharger parasitic losses on Hellcat and Redeye applications, Mishimoto HEMI racing thermostats and CSF Trackhawk radiators that improve heat rejection on track-day and high-output street builds, and Billet Technology billet cap cover and fuse box cover kits that provide a polished under-hood presentation. Granatelli and Cordes Performance engine bay ice tank systems are popular for extended drag strip duty where consistent intake temperature management during staging is critical to repeat performance.

Performance and Handling

An oil catch can on a PCV-equipped performance vehicle prevents combustion by-products from contaminating the intake manifold and throttle body with oil vapor, reducing carbon buildup that causes rough idle and power loss over time on direct-injection and port-injected engines alike. Supercharger pulley upgrades on the 6.2L Hellcat allow boost increases of 2 to 5 psi over the factory 11.6 psi level, with ZPE GripTec's ribbed pulley design also reducing belt slip under high boost conditions that causes premature belt failure. Cooling upgrades including Mishimoto thermostats and CSF aluminum radiators work together to bring operating temperatures down by 10 to 20 degrees Fahrenheit during demanding track use, which protects head gaskets and maintains consistent ignition timing by keeping the knock sensor thresholds unactivated.

Do I need an oil catch can on a Hellcat?

Yes, a Hellcat oil catch can is one of the most recommended maintenance upgrades for the 6.2L supercharged Hemi because the factory PCV system routes crankcase vapors directly into the supercharger intake, where oil deposits accumulate on the intercooler, throttle body, and intake manifold surfaces over time. A properly installed MightyMouse or Billet Technology catch can intercepts these vapors before they reach the blower, extending intercooler efficiency and reducing throttle body cleaning intervals significantly. Hellcat, Redeye, Trackhawk, Jailbreak, and TRX owners all benefit from the same catch can upgrade because the 6.2L supercharged Hemi PCV routing is consistent across all those platforms.

What ZPE pulley should I use on my Hellcat?

ZPE GripTec supercharger pulleys are available in sizes from 2.65 to 3.00 inches, with the 2.85 and 2.75 inch sizes being the most popular street builds that provide roughly 3 to 5 psi of additional boost pressure over the factory 2.95 inch pulley without requiring a fuel system upgrade beyond a Diablosport or HP Tuners tune. The 2.65 and 2.75 pulleys are preferred for dedicated track builds running E85 or E50 flex fuel blends where the higher boost level is supported by adequate fueling. ZPE's GripTec surface treatment reduces the belt slip that causes heat buildup and premature belt failure on smaller pulleys that spin the blower faster.

Why These Parts Fit Right

Engine parts in this collection are listed with vehicle-specific fitment data for the HEMI, Hellcat, Trackhawk, TRX, Camaro, Corvette, and other supported platforms so you confirm the correct product before ordering. Pulley, catch can, and cooling product pages include engine displacement, model year, and trim-level notes to distinguish between 5.7L, 6.1L, 6.2L, and 6.4L HEMI variants. Orders ship fast with expert support available for any engine bay upgrade question.
