USP Marine Tuning MAX+ Forced Air Duct For Mercury V10 Engine FamilyThe USP Marine MAX+ Forced Air Duct is engineered specifically for Mercury V10 engines to solve a well known power robbing problem: the "station wagon effect."

The USP Marine MAX+ Forced Air Duct is engineered specifically for Mercury V10 engines to solve a well-known power-robbing problem: the "station wagon effect." This happens when exhaust fumes get pulled back into the engine intake through the rear of the cowling at speed — causing power loss, reduced top-end performance, and increased fuel consumption. The MAX+ duct channels clean, high-pressure ram air from the top of the cowling directly into the intake, pushing exhaust gases away where they belong.

Designed with the Mercury 400R in mind — the performance leader of the V10 family — this duct maximizes airflow to match the engine's demands. The 400 mainline models benefit equally from the upgrade.

Built in the USA. Built from Fiberglass.

The USP Marine MAX+ Forced Air Duct is manufactured right here in the USA using premium fiberglass construction — the same material trusted in motorsports and offshore racing applications for its superior strength-to-weight ratio, rigidity, and long-term durability in harsh marine environments. Advanced 3D scanning technology ensures a precise, Lego-tight fit to the factory V10 cowling every time. It's surface-prepped with an adhesion primer so it's ready for your color of choice straight out of the box.

Performance Numbers

  • 50%+ increase in ram air intake over the factory duct
  • Significantly reduced intake air temperatures at WOT
  • Retains 2–3 MPH in top-end speed — even more on boats running 100+ MPH
  • Blocks exhaust fumes from re-entering the intake (station wagon effect)

Highlights

  • Fiberglass construction — USA manufactured
  • Race-inspired F1 profile design that follows OE cowling lines
  • Precision 3D-scanned fitment — drops in like a factory part
  • Surface prepped with adhesion primer — ready to paint your color
  • Includes 3M 4000 marine adhesive for a secure, permanent install
  • Larger gains on 100+ MPH boats
  • Air being forced into the engine is Non-consensual 😄

Fitment

  • Mercury V10 350
  • Mercury V10 400 (mainline)
  • Mercury V10 400R
  • Mercury V10 425

Such a pampering treat!
Color: Pink (PDRN)
Ok I love these!!! I’ve started using them almost every morning! They just feel like a little pamper before I start my day. They definitely tighten up my under eye and decrease puffiness. I try to leave them on for 25 min or so. Maybe not quite as good as the Peter Roth but I feel like I can use them frequently due to the reasonable price point and still see some results. I save the Peter Roth for a couple times a month. Definitely repurchasing these.

I love theses eye patches so much! Not only are they very hydrating for the under eye but the price point is *chefs kiss*! They stay in place and do not slide all over your face. Super easy to use. 10/10

Eye patches that work
Color: Pink (PDRN)
Love them! Cooling to the eyes, easy to apply with no slipping. These eyes patches work and they’re great for the price. The only patches I’ll buy going forward. I just apply my eye cream first and then follow with the patches and you can definitely see the results once removing.

Butttttt…
Color: Pink (PDRN)
I wanted to love these soooo bad cause they’re super serum-y , feel great on the skin and I can tell actually difference after wearing. BUTTTT they leave a residue and it’s a nightmare if you do it before makeup. So I will keep but I only reccomend using if you’re not putting on makeup that day!

Repurchasing for sure
Color: Zero Pore Pads, Size: 70 Count (Pack of 1)
These toner pads have genuinely made my skin look smoother, brighter, and more refreshed. They’re super easy to use and feel really gentle while still giving noticeable results. My skin feels cleaner and softer after using them, and I’ve especially noticed improvement in texture and overall glow. I also love that the pads are really saturated without dripping everywhere, and they don’t irritate my skin. They’ve become such an easy part of my routine, especially on days when I want my skin to look extra fresh and glowy. Definitely one of the better skincare purchases I’ve made lately.
