CSF has a long and successful track record with Honda cooling systems. This history includes making factory radiators for Honda Performance Development (HPD). Honda utilized the CSF private label HPD Race Radiator for the FK8 Civic Type R TCR and recently took delivery of a new system CSF developed for the FL5. CSF used the information and experience from building this Race Radiator to design a High-Performance version that would be available to the masses. Like the racing radiator, this new High-Performance version features CSF?s latest 5mm fin cooling technology. The new fin design increases the heat transfer area of the radiator by 20-25% over other larger fin designs.; The original OE radiator from Honda is a plastic tank with a single row aluminum core design. While this is generally accepted as good quality and durable, it is not the best option for high horsepower builds and hard driving. Turbo cars get hot, and the K20C1 is no exception. Anything you can do to help keep temperatures in check will improve longevity of your motor and components.; Just like the HPD Race Radiator, the CSF FL5 Civic Type R / DE5 Integra Type S Radiator features the latest 5mm fin technology. The smaller fins significantly increase the heat exchange surface area improving overall cooling efficiency. A larger 2-Row 42mm aluminum core increases the fluid capacity of the radiator, and improves the cores ability to dissipate heat. CSF?s Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super-efficient multi-louvered fins maximize airflow through the core for the best possible performance. Overall, testing has revealed that the CSF radiator decreases engine coolant temperatures by 6-8% compared to the factory radiator. The TIG-Welded 100% All Aluminum construction increases the overall strength of the radiator. This improves durability and longevity so you can be confident it will hold up to hard driving conditions. The CSF radiator mounts in the factory location and requires no modifications or cutting.; Testing was performed on a FL5 Civic Type R tuned to 294 whp and equipped with an upgraded/larger Front Mount Intercooler. The larger front mount intercooler has been shown to raise engine coolant temperatures by ~7%. This is due to the airflow restriction over the radiator. Test results show a decrease of of 8?C engine coolant temperature with the CSF Radiator vs OEM. As you can see, a radiator upgrade will be very important to anyone running a larger intercooler. The upgraded radiator will also be beneficial to anyone tracking their car.

    Worked well with us!
    Scent: Citrus, Size: 2 Fl Oz (Pack of 1)
    I’ve been trying different products for my daughter’s eczema-prone skin. Her skin was getting really dry, irritated, and rough in certain spots, and this balm has been super moisturizing and soothing. I love that it’s made with simple, natural ingredients and doesn’t feel harsh on her sensitive skin. A little goes a long way, and we’ve noticed her skin staying softer and less irritated after using it consistently. Definitely one of the better products we’ve tried lately 💛

    Natural remedy for treating keratosis pilaris (KP).
    Scent: Unscented, Size: 2 Fl Oz (Pack of 1)
    The most pleasant surprise about this tallow balm is that it’s a very effective natural remedy for treating keratosis pilaris (KP). It’s intense moisturizing properties help smooth the "chicken skin" bumps and reduce redness. It’s a natural alternative to conventional lotions by nourishing the skin barrier without harsh chemicals. I couldn’t believe my eyes when I saw the skin texture on the back of my upper arms after rubbing it in. My skin looks and feels much improved when I use it and hopefully will continue to improve over time with continuall use! If you have not found an all natural product to help smooth and reduce KP bumps give this tallow balm a try!

    Scent: Lavender, Size: 2 Fl Oz (Pack of 1)
    Love this tallow balm. I use it nightly after my serums and also mix with my foundation so it glides on my dry skin and it looks wonderful. A tiny bit goes a long way. The lavender is a light scent and smells so good. My skin has zero sensitivity to this and in the morning my skin looks great and feels so soft.will be buying mote of this . Excellent for dry skin.

    This balm is Magical!
    Scent: Vanilla, Size: 2 Fl Oz (Pack of 1)
    This product was a life saver! After using the same face moisturizer for years, I suddenly became allergic to it. Overnight my face became swollen, red, sores that oozed, it was disgusting, embarrassing, and painful. I was diagnosed and treated for impetigo- which I knew was not the cause. But I didn’t know the cause until it cleared up and I went back to the old moisturizer because I was sure it couldn’t be that after years of use. But it was and I had another outbreak. So I researched an American made product and found this balm. It is magic! Within a week of using it the symptoms were gone! I love the scent, the protection it provides, and just how very soothing it is on my face. It is the right thickness to keep my face from dryness all day long. I love the feel of adding a glow to my skin with a rich oil that is pure and allergy free. I’m on my second jar and will be a loyal customer from here on out!
