Mishimoto is proud to release a direct-fit silicone boot kit with DuraCore™ technology designed specifically for the 2017-2019 Chevrolet/GMC 6.6L L5P Duramax. Mishimoto DuraCore™ technology is a synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots. Compared to normal silicone, DuraCore™ 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, these couplers feature stainless-steel reinforcing rings to prevent expansion under high pressure that may result in a blowout and lost boost pressure. This kit also includes Mishimoto stainless-steel constant-tension T-bolt clamps for a reliable and consistent seal. As with all our products, this boot kit is protected by the Mishimoto Lifetime Warranty.This Part Fits:

Perfect fit and great quality for the price
This suit was perfect for my son. The fit was exactly as expected. The quality is excellent for the price—it feels well made and durable enough to last through multiple wears. It doesn’t feel cheap or flimsy at all.
It also looks really good on him. Clean, polished, and great for formal events like weddings or parties.
Overall, a fantastic value with great quality and a great fit.

Missing items
Color: Sky Blue, Size: 16
Was missing the tie that is supposed to come with it and it looked like it was tried on and thrown back in the bag. The sleeve to the jacket were rolled up.

Excellent Quality, Great Value, Great Look. Highly Recommend
Very well-made, there are some minor imperfections in the cuff sewing that aren't really noticeable when on. Liner is quality, color is spot on, and it fits true to size. If you're in the market for a toddler blazer and pants, you can't go wrong with this one in terms of quality, price, and the cut is perfect for a very polished look.
There were a few loose strings to be clipped, but everything was correctly sewn and well. None of them affected the seam strength. The pants have a button and elastic on the waistband to make adjusting the waist size easier.

Great boys slim fit suit for weddings, church, or special events
Color: Medium Grey, Size: 12
Great kids suit. Comes with a jacket, pants, and tie. Does not have a shirt. Fits as expected. Classic cut on the lapels. Great quality materials. Well made pants and jacket. The color is consistent without any fade or dark spots that can happen with lower quality fabrics. Looks great on. My son loves it. Says it is not restrictive, he can move easily in it. Highly recommend for church, special events, weddings, etc.

Nice high-quality, light weight suit for a tween!
Color: Navy Blue, Size: 10
This is such an attractive suit for a tween boy! My son loves dressing up, and this is his new favorite suit. He really likes the double-breasted style and the light weight of the fabric so that it isn't too hot. The tie that came with it gives major Harry Potter vibes which we weren't expecting, but he has lots of other ties that he also enjoys pairing with it. The size seems right, and it fits him well. He says it is very comfortable. I'm happy with the quality and the navy color.
