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.Shipping Notes

Rubberized fun for your little ones
Pattern Name: Animals
If your pet baby loves squeaky toys, then these are right for them. Value for the money. Soft rubber, durable squeaker, and they bounce like a ball. I should say a ball that ricochets off of anything it bounces off of. Loads of fun for the little dogos.

Essential Dog Toy in "Our World"
Pattern Name: Funny Faces
I have bought ~a dozen of these packs over the last 7 years. Began when our cocker was a puppy and (with puppy teeth) prone to destroying each squeaky toy he loved. Searched on something like "non-destructible (or maybe durable) small dog squeaky toys)" and these popped up. Now, they're Bark Park playtime essentials. SO many pups there love them (and we let the "stealers" keep them and tell their parents how to get them. Every day we have Bark Park squeaky egg symphonies (one mini Aussie plays 3 simultaneously--2 by mouth; another with his foot) and chases, as ALL the doggos love them. They last a long time and can be washed (I use a toothbrush and block the hole w. a finger).

perfect size
Pattern Name: Animals
these are the perfect " Goldilocks " size for our 3 month old frenchie! Not so big he cant bite them and squeak them and not to small where i worry they could slip & choke him. just a heads up the squeak is pretty loud lol they also are very soft both in texture and in terms of being able to squeeze. thy can bounce a bit which he loves too. the green one for some reason is thicker and harder for him to bite & squeak so he doesnt really play with that one. so far they are holding up to his puppy teeth but i suspect if you have a aggressive chewer they wouldnt do so good. very happy with the purchase. and as you can see in my video so is our little man lol

Indestructible for our 8 pound Mi-Ki
Pattern Name: Funny Faces
Our small dog loves these and he hasn't been able to chew them up. He loves their unpredictable bounce and chases them all day. He also likes to sleep surrounded by them.
