Is your big block running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller with 16 vanes, integrated shrouding and a reduced casting-to-impeller vane clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot BBC engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

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.
