When you're fabricating a custom intercooling system, every component in your build needs to pull its weight. Mishimoto DuraCore(TM) Silicone Intercooler Boots are engineered to be the strongest link in your intercooler piping kit. -- Whether you're routing charge pipes around tight engine bays or connecting mismatched tube diameters, we have the sizes and configurations to match exactly what your fabrication requires. DuraCore(TM) boots are available in straight, straight hump, transition, 45-degree, and 90-degree configurations, with sizing from 3" to 4", giving you the flexibility to complete your piping kit without compromise. Whatever your layout demands, Mishimoto has every size and shape to meet your build. -- DuraCore(TM) technology is the synthetic material comprising the innermost layer of every Mishimoto silicone boot. Compared to standard silicone, DuraCore(TM) delivers superior resistance to heat, pressure, fuel, and oil, effectively extending boot life by preventing leaks and blowouts under high-boost conditions. Each boot is manufactured from five layers of silicone with heat-resistant embedded fibers, and reinforcing rings (where applicable) add structural integrity to keep connections secure under pressure. Hump-style couplers introduce additional flexibility to absorb movement and vibration without compromising the seal. -- You've put serious work into your truck build. Don't let the boot be your failure point. With DuraCore(TM) Silicone Intercooler Boots, it never will be.

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Solid interactive automatic vibrating dog ball toy
Color: Blue, Color: Blue
Picked up this ITEHZTO interactive automatic vibrating dog ball for our pup and it’s a fun, engaging toy that keeps her entertained. It’s rechargeable with USB, motion-activated, and has a good vibrating/rolling action that gets her chasing and playing on her own. The durable build seems like it can handle some rough play, and it’s a nice size for indoor or outdoor use. It lights up or vibrates when activated which adds extra excitement, especially during evening playtime. Battery life is decent and recharges quickly. Great for when she needs mental and physical stimulation without me having to throw a ball constantly. Overall a solid interactive dog toy that does a great job keeping active dogs busy. Good value if your dog loves chasing moving/vibrating toys!

Built-in USB-C solves the power issue, but it is strictly for moderate chewers
Color: Blue
Got this to keep the high-energy puppy occupied indoors so the older dogs can actually get some peace and quiet. The main issue with most automated electronic pet toys is that they rely on expensive, hard-to-find button cell batteries that die after a single afternoon of use. This unit utilizes a built-in 300mAh battery with a standard Type-C charging interface. That is a mandatory design feature if you actually want to run the toy daily without going broke replacing power cells. The internal motor generates enough erratic movement to keep a dog's attention, and it actually has the torque to navigate over standard tile, hardwood, and light carpets without instantly stalling out in a corner. You need to completely understand the physical limitations of what you are unboxing here. The listing explicitly states this is not for heavy chewers, and you need to take that warning seriously. The outer shell is TPU, but the internal chassis housing the electronics is hard ABS plastic. If you hand this to an 80-pound working dog that aggressively shreds thick bones, they are going to crush the housing and destroy the internal motor assembly in about ten minutes. At roughly 2.5 inches in diameter, it's basically the size of a standard tennis ball. If you use it as intended—as an interactive chasing toy for a puppy or a moderate chewer rather than a heavy-duty chew toy—it functions perfectly. It is a highly practical piece of indoor enrichment gear. Solid return on investment for burning off excess canine energy.

Pawsitively Stimulating🐾
Color: Blue
When my hooman brought this home, I thought it was fur their computer. After all, it has a plug and lights up. When they placed it on the floor, I was pawsomely surprised. Fur real, this little ball is wierd. It doesn't taste at all like my favorite tennis ball. I was a pawplexed that sometimes when I was finally brave enough to get it and hold it in my mouth, it would start jumping around. I think my hoomans finally found a toy that will keep me busy for a while. Mom is howling with excitement because it kept me interested for a long time. I hope I can sleep tonight. I see mom has plugged in my new toy to keep it "charged"- whatever that means....I never had a toy that came with its own leash before. Mom says she is gonna save the toy until other hoomans come over to keep me from being too ruff with them. You see the video, do I look a dog who could be too ruff?- Sincerely, the family dog, a bona-fido toy reviewer
