Looking to extract more horsepower and torque from your Infiniti Q50 Sedan or Q40 How does around 400WHP grab you Add a dose of torque, better-than-stock heat management and airflow, and near stock fuel economy at low RPM. Now you've got the formula for superchargers done the STILLEN way. We're talking driveable horsepower too, suitable for daily drivers, canyon carvers and track days.
What does 'driveable' mean
Take an unsuspecting passenger for a low RPM cruise around town in your STILLEN supercharged Infiniti Q50 Sedan or Q40. Keep a light touch on the gas pedal and they might be fooled into thinking there's a bone stock motor under the hood. They won't suspect a thing....until you hit the town limit sign and crack the throttle wide open.Scenery gets blurry-in-a-hurry as the centrifugal Vortech blower spins up to hyperspeed with a telltale hiss. The STILLEN designed and built intake manifold sucks in cubic yards of cool air. The remapped ECU fuel management module jacks the boosted fuel pump to inject the precise amount of high octane cocktail into the maelstrom.
Your right foot is orchestrating a symphony of controlled violence that delivers a linear, bottomless powerband. If you can peel your head off the headrest to sneak a glance at your passenger you'll see instant enlightenment and heavy G's at work.
A YEAR IN THE MAKING
You might think it all sounds like witchcraft. But there are no spells and potions involved in creating this enhanced driving experience. Designing this supercharger system for the Q50 Sedan or Q40 involved precision engineering and innovative problem solving - a STILLEN specialty!Much of the year-long development and testing process surrounded the ECU fuel management settings. STILLEN engineers remapped the ECU fuel management settings for the supercharger system to manage the improved airflow, operating temps and huge power gains, all while achieving 50 state emissions compliance**.
The complete supercharger kit includes larger injectors and a new fuel pump to match the remapped factory ECU.
A BULLETPROOF BUILD
STILLEN designed a new cast aluminum intake manifold specifically for this system, featuring longer runners and a large plenum for the engine to draw air. An integrated air-to-water intercooler system dramatically cools the air charge from the Vortech V-3 Supercharger unit.
The V-3 features a self-contained oiling system and quiet V-belt design, with plenty of additional boost capability for those wanting even more power down the road.
STILLEN took extreme care in designing this system, ensuring that all additional coolers (oil, transmission, power steering, etc) would work with the intercooler system, as the Nissan VQ37 engine is prone to high oil temperatures unless properly cooled.
At all levels of development the system was tested, both for street drivability and reliability under normal traffic and freeway conditions. Stillen drivers flogged the test car at El Toro Air Base, with repeated 140+ mph runs and hard driving on tight courses with excessive revving and redlining. Testing included extensive monitoring of all pertinent air and fluid temperatures.
2 OPTIONS
WITH CABLE OPTION
To tune these supercharger systems STILLEN works with UPRev software. This software requires a license and a cable to load the tune into the vehicle's ECU. The With Cable option is designed for customers who may not live near an UPrev certified tuner or for a dealership who is completing the installation. This is also a great solution for the DIY guy looking to install the kit in his garage.
WITHOUT CABLE OPTION
The "without cable" option is supplied with all of the hardware and the tune. This solution is good for someone who is working with an UPrev pro tuner that already has the licenses and loading cable in their facility. This way you don't need to pay extra for something you might already have access to. Either way, the tune is the same.
STRAIGHT FORWARD INSTALLATION
One of the hallmarks of a STILLEN supercharger is ease of installation. Much of the assembly of the kit is completed here at STILLEN before we pack and ship your supercharger. The main supercharger unit is pre-assembled to the laser-cut billet aluminum mounting brackets. Installation is very straight forward, including detailed step-by-step instructions. Typical install time for a competent shop is 12 hours.THE FINE PRINT
*Individual results will vary depending on baseline condition of the stock engine, type of dynamometer used, temperature, elevation, fuel and various other factors. Typical results are around 400WHP (wheel) at under 500' elevation and below 75 degrees F. Typical output range 380WHP - 450WHP depending on level of modification, fuel octane/quality, engine age/health, elevation/sea level and the weather that particular day.**50-state compliance currently for 2014-2015 model years.

LOVEE (combo & oily skin) 🥹
Size: 3.38 Fl Oz (Pack of 1)
Pretty good! I loveee the applicator since it makes it really easy to apply. My skin has been super glowy ever since I’ve used this. Consistency is super thin and lightweight. My skin doesn’t exactly feel soft but looks really smooth. Despite it being this way, it hydrates super well!

My Go-To Toner After Trying Many Others
Scent: Unscented, Size: 12 Fl Oz (Pack of 1)
I’ve tried many toners over the years, including higher-end brands, and this one continues to stand out for both performance and price. It does exactly what I need without unnecessary extras.
The formula feels gentle and effective, and I really appreciate that it’s alcohol free and fragrance free. Those two things are especially important to me, and this has been the only toner I’ve felt comfortable using during pregnancy. It doesn’t irritate my skin and fits easily into my daily routine.
Despite the affordable price, it performs just as well—if not better—than many more expensive options I’ve used in the past. My skin feels clean and refreshed after using it, without any tightness or residue.
Overall, this is a reliable, no-nonsense toner that delivers great results at a very reasonable price. If you’re looking for a simple, fragrance-free option that works well without breaking the bank, this is an easy recommendation.

Liquid facial magic!
Scent: Coconut Water, Size: 12 Fl Oz (Pack of 1)
I love this stuff. I use it daily as part of my facial routine and it has become one of those products I don’t even think about anymore because it just works.
It smells good without being overpowering and does a great job of helping control excessive oil buildup on my face. Nothing harsh, nothing drying, just clean and refreshed skin. Right after using this, I follow up with a facial moisturizer and the combo works beautifully. My skin feels balanced instead of tight or angry, which is exactly what I’m going for.
I know the label says men can use this as an aftershave, but that’s a hard pass for me. I stick to soothing, purpose-built post-shave products, specifically from Wholly Kaw. That stuff smells like it was handcrafted by skincare deities who truly care about your face. This toner is staying firmly in the “daily skincare” lane, where it shines.
Another big plus is how gentle it is. No burning, no weird tingling, no regret. Just a calm, refreshing step that makes my skin feel like it’s being treated with respect.
And the price? Under $10. That alone keeps me coming back. Honestly, I think they could charge a few dollars more for how well this performs, but I won’t complain about paying less for fantastic facial liquid magic.
Simple, effective, affordable, and a permanent part of my routine. My face approves.

Lasts awhile! Good product
Scent: Rose Petal, Size: 12 Fl Oz (Pack of 1)
Cleans without overdrying. Leave skin feeling clean, no stickiness. Pleasant light scent that doesn't linger. I get my moister from other products so this one idk if it moisturizes by itself. Good value for the money, you get a lot so it lasts awhile.
