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.

FUN AND DONE!
Color: Orange
First, I looove that I could get this dog toy in my favorite color! The orange color also helps to locate it, if your doggo has rolled it somewhere you don't know. This bowl toy is very durable, safe, and easy to pull open and fill. The only reason I don't give it 5 Stars is because the opening is so big, after it's closed, that unless you have pretty large pieces/treats in it, or jam-pack them in, they easily fall out, when my dog rolls the toy around. What I do, is put a whole Greenie in the bowl and then add treats around it. She's thrilled to have a treat or two spill out, as she rolls the bowl around. But what really keeps her occupied is trying to get to the Greenie. This is where the durability plays such a key role! Our dog is a Pit-Terrier and an extremely aggressive chewer, but the fold in the bowl is so strong that even her attempts to chew through it or claw it out don't work. That said, I would still supervise your dog's play with this. I know, if she really wanted to, our dog could eventually chew through the strong material to get to the Greenie, but thank goodness it's too thick and too wedged in to be worth all that time. The awkward shape of the bowl also makes it hard for her to grip it in her mouth foe chewing. For a dog's quick fun, amusement, and reward, this is a winner!!

After two years pups still love this
Color: Blue Lil Snoop
My pups really love this ball and they spend a long time trying to get kibbles or freeze dried chicken. It’s been 2 years since purchase and it’s still in good shape. I highly recommend.

Great for mental stimulation. Durable for my chewers!
Color: Purple Lil Snoop, Color: Purple Lil Snoop
Love these! Quality material, safe for dogs β€” I make my dogs home made freezer treats and fill these up with it, and serve. Keeps them busy for hours. It’s also fun for them to roll it around to get regular treats out of. Toy + treats = a very happy pup. This size I got for my puppy. The larger ones I use for my adult dogs. Super cute too, and silent! I have Mini Aussies, so it’s great mental stimulation for them. Tires them out.

No challenge once they figure it out once, or if they have a long nose
Color: Blue
The first time I used this with my 9 month old Shepard mix, it was great. We used about 1/3 cup of her kibble and added the Nook to make it harder. It kept her working for 20-30 minutes. However, now that she knows how to remove the Nook, and stick her snout into the opening and lick up the kibble, it lasts about 5 minutes, and is no longer a challenge. She still enjoys playing with this, even when it is empty, and hasn't it destroyed it yet, so for that 3 stars.

Awesome toy, add peanut butter
Color: Blue, Color: Blue
I love this, and so does my dog! Yes, plain kibble can fall out too easily, so I put a blob of peanut butter in too and that helps it stick better. Bigger treats work great, as well. Its big and slippery enough that she can't rip it apart, which is great. Absolutely recommend, it's cute to see my dog flip and nose this around. I will probably getting the purple one too, as they are quite affordable. A+
