AEM tested many sensors with the 30-4110NS, including popular inexpensive knockoff sensors, and determined that only the following sensors will deliver reliable performance:

Using the above sensors ensures that the factory sensor calibration is accurate and that the controller performs optimally. The use of any non-approved sensor may affect the controller’s operation, and will void the warranty of the 30-4110NS.

WHAT IS A WIDEBAND UEGO AIR/FUEL CONTROLLER?
AEM's Wideband UEGO (Universal Exhaust Gas Oxygen, pronounced “You-Way-Go”) Controllers are powerful, cost effective tuning tools that allow users to accurately monitor the Air/Fuel Ratio (AFR) of their engine.

WHY USE A WIDEBAND AIR/FUEL CONTROLLER?
Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.

Glowing face with sun protection. No fuss, no muss!
Item Package Quantity: 1
Wow, I love this stuff. It does make your skin hydrated and glow with health while protecting it from the sun. No shiny oil, just glow, and best of all, no need to mess up your makeup reapplying sunscreen. You can use it to set your makeup for extra protection (I still use sunscreen under makeup). The mist comes out so fine and even, no drips or glob. The scent is light and fades quickly. The best I've dried out of all the other brands.

Lightweight and glowy
Item Package Quantity: 1
I’ve been using the Naked Sundays SPF 50 Hydrating Sunscreen, and it’s quickly become a staple — especially for long days outside and on the tennis court. The texture is lightweight and smooth, and it blends in beautifully without leaving a white cast or greasy feel. What I love most is the finish: it gives a natural, healthy glow without looking shiny or heavy. It layers really well under makeup and doesn’t pill, even when I’m reapplying throughout the day. I also appreciate how hydrating it feels without clogging pores or causing breakouts. Performance-wise, it holds up well during activity and sweating (which matters for me during matches). The packaging is easy to toss in a tennis bag for quick reapplication. If I had to note one thing, it’s slightly pricier than drugstore options — but the quality and wearability make it worth it. Best for: everyday wear, outdoor sports, and anyone wanting high SPF protection with a comfortable, skin-like finish. Would absolutely repurchase.

Stings! Waste of money! Doesn’t accept returns!
Item Package Quantity: 1
Very disappointed with this spray sunscreen. Although I’m usually not sensitive to sunscreens or face creams in general, this product made my eyes burn and tear up so much and so fast that I’m not able to use it. Such a waste. I even tried applying while covering just my eyes to avoid that area and it still stings. And it also goes on greasy, definitely not cute glowy looking. It is not a flattering shine. For the price I’m very disappointed and even upset that I didn’t notice before buying that you cannot return it. Don’t waste your money.

☀️ Holy Grail SPF Mist! especially for makeup days 💦
Item Package Quantity: 1, Item Package Quantity: 1
If you hate the feeling of greasy sunscreen but still want serious protection, this is the glow-up you’ve been waiting for. I use this as the last step in my morning skincare and as a top-up over makeup throughout the day. It’s lightweight, non-greasy, and gives a dewy finish without looking oily, just a fresh, hydrated glow ✨ The mist is fine and even (no big droplets or weird stickiness), and it dries down fast. No white cast, no clogged pores, no breakouts. Just SPF 50+ that actually works with your makeup instead of wrecking it. I’ve even used it midday at Disneyland and didn’t burn once, and I’m someone who burns if I think too hard about sunshine 🥵 Helpful hint: Shake it well before spraying, and hold it about 6 inches from your face for a nice even mist. One pass usually does the trick, but I like to go back over my nose and cheeks for extra protection ☁️ It also doubles as a midday makeup refresher, especially when your foundation starts looking a little dry 🧴 I brought this with me on a full weekend trip to Disneyland and it absolutely earned its spot in my park bag 🎒 I was in the sun all day, both days, and didn’t burn at all, even with minimal shade and back-to-back rides 🎢 It layered like a dream over makeup, didn’t feel heavy, and made touch-ups fast and easy in between churros. This mist officially passed the Disneyland test. 🎡☀️💕

Good but heavy smell
Item Package Quantity: 1
I will keep using this bc it works and the sprayer is sooo nice but the smell is so overwhelming. It’s not a bad smell but it’s just so heavy. I’ll use this one but I don’t see myself repurchasing.
