Must Use Skunk2 P/N: 312-05-0010 (Spring Bases) to Install Dual Springs in Single Spring K Heads or to Install in F20C/F22C Engines. Skunk2 is proud to introduce its Pro Series XP (Extra Pressure) Racing Valve Spring Kits for the Honda K-series i-VTEC engines. Each kit includes Skunk2's high-quality race-proven dual valve springs that are the result of nearly two decades of racing and engine building experience. "XP" features a higher seat pressure for turbocharged and extreme high RPM motors. This spring has a seat pressure of 100lbs @ 1.600" while keeping the coil bind height for higher lift camshafts. Each Pro Series XP Racing Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Pro Series XP Racing Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 11,000 rpm. Wound by a premier North American winder, our Pro Series XP Racing Valve Springs retains its durability and strength that results in improvement to the extreme fatigue limit of the wire and enhanced resistance to load loss. Pro Series XP Racing Valve Springs are engineered to handle the demands of extreme-lift camshafts operating at prolonged, high-rpm use at championship-level racing. Skunk2's Pro Series XP Racing Valve Spring's for the Honda's K-series i-VTEC engines are simply the best on the market. Pro Series XP Racing Valve Springs have been tested at speeds exceeding 11,000 rpm on our engine dyno, street, and the race track. Our superior, Japanese-milled, super-clean chrome silicone wire is 100-percent eddy-current inspected prior to coiling. Next, they are heat-treated, shot-peened, and chemically polished for strength and durability. A special nitriding process concludes Skunk2's rigorous manufacturing process.

From dry to soft in days.
Size: 3.38 Fl Oz (Pack of 1), Style: 3.38 Fl Oz (Non SPF)
I bought this moisturizer at a time when my skin truly needed help, with mature and sensitive skin, and I was dealing with intense dryness. My skin felt tight, dull, and uncomfortable, even after trying several products that didn’t provide lasting hydration. I decided to try this cream and within the first few days, I noticed a real difference. It’s lightweight, absorbs quickly, doesn’t feel greasy, and most importantly, it doesn’t irritate my skin—instead, it soothes it. With continued use, my skin became softer, more supple, and visibly healthier, without that constant tight feeling. I love that it’s fragrance-free, oil-free, and non-comedogenic, as it hasn’t caused any breakouts. It also contains ceramides and niacinamide, and the added SPF makes my routine much easier. After trying many products, I can honestly say this is the only one that truly worked for me. It’s now a daily essential.

Nice!!
Size: 3.38 Fl Oz (Pack of 1), Style: 3.38 Fl Oz (Non SPF)
This has become one of my favorite skincare products. I previously used Neutrogena Hydro Boost along with a separate moisturizer because I wanted hydration without feeling greasy, but this product feels like the two had a child and combined the best qualities of both. It provides all-day hydration, yet it never leaves my face feeling oily, heavy, or sticky. The texture is lightweight and absorbs quickly, making it comfortable to wear throughout the day and under sunscreen. My skin feels moisturized for much longer than it did with my previous routine, and I appreciate that I can get the hydration I want without that shiny, over-moisturized feeling. Highly recommend for anyone looking for a lightweight moisturizer that still delivers lasting hydration.

Moisturizing & repairs skin barrier, but does pill.
Size: 3.38 Fl Oz (Pack of 1), Style: 3.38 Fl Oz (Non SPF)
Given myself a couple weeks of consistent use before giving a review. There are a lot of pros to this product which include: moisturizing and stays moisturized all day, made my PIE marks (post acne marks) fade a lot faster. Repairs my skin barrier, especially while using tretinoin nightly, not too thick but thick enough to keep my face hydrated. It does not have a smell. The cons are: slight burn for about 15 seconds but disappears, it pills if I apply too much. It does pill less if I pat it on my face versus rubbing; it does not pill when I apply liquid foundation. I just have to let it dry for 15-20 mins before applying makeup. I found the pros to overpower the cons and will continue to use this product.

Great daily lotion
Size: 3.38 Fl Oz (Pack of 1), Style: 3.38 Fl Oz (Non SPF)
Great daily lotion. I love that it is light and fragrance free. It is perfect for day use. I have dry skin and sometimes it is not enough to use by itself. I mostly use it during the day as a base for sunscreen but it feels really good on the face and does not leave my face feeling greasy. The ingredients are really good and the value for money is great. I love LRP products and this is so easy to use.
