Improve the power and efficiency of your 2017-2019 Chevrolet/GMC 6.6L Duramax L5P with our Mishimoto intercooler pipe and boot kit. The factory L5P intercooler pipes are a measly 2.5in diameter that chokes the engine, while tight bends and a resonator on the hot side create even more restriction.The Mishimoto intercooler pipes are 3in in diameter throughout with smooth transitions to significantly increase airflow, resulting in more power potential. Our hot-side pipe also eliminates the stock resonator for maximum flow. Combined, the Mishimoto intercooler pipes are up to 55-percent less restrictive than stock.Both the hot-side and cold-side utilize a two-piece design for ease of install. To connect the pipes to our Duramax, this kit also includes our silicone boots with DuraCore(TM) technology. Mishimoto DuraCore(TM) technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore(TM) provides superior resistance to heat, pressure, fuel, and oil. This effectively increases the life of our boots by preventing leaks and blowouts.To add even more reliability, this kit includes Mishimoto constant-tension T-bolt clamps for accurate and consistent holding power. Our cold-side intercooler pipes also feature a CNC-machined quick-disconnect fitting with new O-ring and spring clip to ensure a secure and leak-free fit. Unlike other available pipes on the market, our pipes retain the intake air temp harness mounting location for safe and secure wire routing, just as Chevy/GMC intended. Our intercooler pipes also incorporate two bungs that can be drilled and tapped for sensors, so you can easily monitor your L5P's performance.The Mishimoto 2017-2019 Chevrolet/GMC 6.6L Duramax L5P intercooler pipe and boot kit is a direct bolt-on upgrade and is available in a polished or wrinkle black powder coated finish. Like all our Duramax products, this kit includes our Mishimoto Lifetime Warranty.Shipping Notes

Indestructible
Color: Green, Pattern Name: Multi Color
Ordered these on a sale..I thought there were 4 bones, but only 2...I have 2 American bullies and 2 Micro bullies..All heavy chewers..These work perfectly for them and they love them...I actually had to order another pack full price so that there was 1 for each dog. Happy with my purchase, happier with the sale price but all 4 like them and can't destroy them so it's a good purchase.

My Pup Said No Thank You
Color: Green, Pattern Name: Multi Color, Color: Green, Pattern Name: Multi Color
⭐☆☆☆☆
My dog usually loves toys like this, so I was excited about them—especially since the colors were fun and it came as a pack of two. Unfortunately, my dog didn’t like these at all and kept choosing her older chew toys instead. They just didn’t hold her interest, which was disappointing. Overall, not worth the money for us.

Update after a week of having this toy
Color: Green, Pattern Name: Multi Color
I thought these were going to be more like a hard rubber but they are a very hard plastic.
Keeps my dog busy but best to be supervised while chewing on it.
I don’t let her have it when I’m not around so she doesn’t damage her teeth.
*UPDATE*
The dogs are absolutely obsessed with these toys.
I was worried at first it was going to hurt their teeth and gums but they don’t.
These have been a great addition to their millions of toys lol.
Very happy with my purchase

Very sturdy chew toy
Color: Bacon
My Frenchy loves it! He’s not a large dog, but big for a French Bulldog. (32 lbs). He chews both ends, but prefers the snout. The eyes are cute, but began to peel off within the first week. I easily removed what was peeling. Half of the paint remained intact. When necessary, I will definitely replace it with the same toy.

Great chew toy, long lasting
Color: Bacon
This chew toy has been amazing. We have had it for 2 months with 2 dogs chewy on it and it is still going strong. We have a large Golden who chews on everything and and German Shepherd. Big dogs who chew aggressively. Very impressed! Would definitely buy again!
