Do I really need an oil catch can?

Yes, especially on direct-injection engines. Modern engines route crankcase vapors back into the intake via the PCV system. These vapors contain oil mist, fuel residue, and moisture that coat intake valves with carbon deposits over time. On direct-injection engines (like the Coyote 5.0, EcoBoost, LT1/LT4, and HEMI), there are no port fuel injectors to wash the valves clean — so carbon buildup is inevitable without a catch can. A UPR catch can intercepts these vapors before they reach the intake, keeping your valves clean and your engine running efficiently.

What is the UPR Plug N Play system?

Plug N Play is UPR's patented push-button quick-release fitting system . Instead of cutting hoses and using hose clamps (like most competitors), UPR fittings snap directly onto your factory PCV connections — press the button, push the fitting on, and it locks. Installation takes 10-15 minutes with no tools, no cutting, and no modifications. Servicing is equally easy: press the button, pull the line, drain the can, and snap it back. No other catch can brand offers this.

What is the difference between single valve and dual valve catch cans?

A single valve catch can manages one side of the PCV circuit — typically the dirty side (valve cover to intake manifold). A dual valve catch can manages both sides — the dirty side AND the clean side (fresh air inlet). Dual valve systems provide complete crankcase vapor management and capture significantly more oil. For maximum engine protection, UPR recommends a dual valve system or a single valve can paired with a Clean Side Separator (CSS).

How often do I need to drain a UPR catch can?

It depends on your driving habits, engine condition, and whether your engine is forced induction. As a general guideline, check every 1,000-3,000 miles during break-in and normal driving. Turbocharged and supercharged engines typically collect more oil and may need draining more frequently. With UPR's Plug N Play system, draining takes less than 60 seconds — just press the button, pull the can, pour it out, and snap it back.

Will a catch can void my factory warranty?

Under the Magnuson-Moss Warranty Act , a dealer cannot void your entire warranty simply because you installed an aftermarket catch can. They must prove the catch can specifically caused the failure — which is virtually impossible since catch cans improve engine cleanliness. UPR catch cans are non-invasive (Plug N Play requires no cutting or drilling) and are fully reversible, making them one of the safest modifications you can make.

How does UPR compare to Mishimoto catch cans?

UPR and Mishimoto take fundamentally different approaches. UPR uses CNC billet 6061 aluminum (machined in Florida), patented multi-chamber coalescing filtration, forged aluminum Plug N Play fittings, and Continental braided hoses rated to 300 PSI. Mishimoto uses cast/welded aluminum (manufactured overseas), a baffled internal design, standard hose clamps, and silicone hoses. UPR installs in 10-15 minutes with no tools; Mishimoto typically requires 30-45 minutes. UPR offers an unconditional warranty; Mishimoto offers a limited lifetime warranty.

Does UPR make catch cans for supercharged and turbocharged engines?

Yes. UPR offers specific catch cans for forced-induction applications including Whipple, VMP ODIN, Roush, Paxton/Vortech, ProCharger, Edelbrock, and Hellion supercharger kits as well as factory turbo engines (EcoBoost, Supra). These boosted-application cans include UPR's patented one-way valve that releases excess crankcase pressure to atmosphere under boost while still capturing oil — preventing boost leaks and crankcase over-pressurization.

Where are UPR Products made?

Every UPR catch can and accessory is designed, CNC machined, and assembled in Lake Worth, Florida, USA . UPR operates from 20,000 square feet of manufacturing space with in-house CNC machines. All components — billet aluminum bodies, forged fittings, Continental hoses, Viton O-rings — are sourced from quality suppliers and assembled domestically.

Does FFP install UPR catch cans?

Yes. Our technicians at our Thousand Oaks, CA shop install UPR catch cans regularly. While UPR's Plug N Play system is designed for easy DIY installation (10-15 minutes), many customers prefer professional installation for optimal routing, clean cable management, and peace of mind. Walk-ins welcome during business hours.

What is the UPR Clean Side Separator (CSS)?

The Clean Side Separator (CSS) filters the fresh air inlet side of the PCV circuit — the side that most catch cans ignore. When oil vapors travel through the PCV system, some escape through the clean side back into the crankcase. The CSS intercepts these vapors, providing complete PCV management. UPR recommends pairing a dirty-side catch can with a CSS for maximum engine protection, especially on high-performance and forced-induction builds.
