Skunk2 Ultra Series Valves for the Honda K20 and K24 are Skunk2's premium line of valves; manufactured from HNV-3 martensitic steel (IN) and EV8 austenitic steel (EX) one-piece forgings. The characteristics of the austenitic nickel based alloy enable high resistance to oxidation and corrosion and are designed for engines that output extremely high temperatures. Ultra Series valves are heat-treated using a proprietary process for extraordinary strength and durability and Chromium Nitride coated using the physical vapor deposition (PVD) process. This coating significantly improves wear and heat resistance, creating conditions for more durability and long term usage. Chromium Nitride coating is a remarkable solution as it improves the friction coefficient between the valve’s stem and valve guide; a necessity for engine components that demand resistance to high heat level environments.

Other valves may appear similar, but only Ultra Series Valves feature specially designed valve head profiles to optimize airflow. Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. Skunk2 valvetrain components provide exceptional performance, reliability, and quality and are standard-issue on each Skunk2 vehicle that we build and support.

My first choice to make my mouth fresh and clean
Size: 16 Fl Oz (Pack of 1)
I have a lot of trouble sleeping and using the sleep apnea machine dries my mouth. This mouth wash is my favorite for feeling clean and refreshed. It really helps with that dry mouth I get from using the sleep apnea machine

Really solves dry mouth with a great taste and convenience.
Great tasting lozenges that actually work and offset dry mouth. They have a cool, refreshing taste. I've had dry mouth issues for years and found these to be the best and prefer the lozenges over Biotene's other products. I carry a sleeve with me at all times and leave one in the car. I really love this product.

Work great for instant relief of dry mouth.
They work great for a dry mouth. I like them a lot more than the Biotene Dry Mouth Spray or mouth wash. They taste good & relieve the super dryness that occurs due to my low electrolytes. Plus, I can carry them in my purse or to the gym.

Great product!
I get a dry cough from occasional acid reflux and these lozenges have really helped manage a flare up. They really do the job. These are not cough drops per se, but they seem to coat the throat and help keep coughing spells at bay.
