Mishimoto has expanded our line of Duramax performance parts to include a performance intercooler for the 2017-2019 Chevrolet/GMC 6.6L Duramax L5P.High intake temperatures can reduce performance and potentially cause engine damage if left unchecked. Protect your investment by upgrading to the Mishimoto 6.6L Duramax L5P performance intercooler. This Duramax intercooler is precision engineered with durable cast-aluminum end tanks that resist cracking under high temperatures and boost pressures.The massive 68mm-thick bar-and-plate core is 70-percent thicker than stock and is designed for maximum cooling. In addition, the larger core reduces restriction by over 64-percent compared to the stock intercooler. We've also increased the size of the intercooler inlet and outlet by 6mm and 12mm, respectively, to improve flow even more.Included with this intercooler is an adapter cold-side pipe with DuraCore(TM) boot and constant-tension T-bolt clamps. Two additional bungs on the adapter pipe can be drilled and tapped for sensors or water/meth injection.

Good value for a $55 boot.
Size: 12, Color: Army Green
I like these boots because I have a wide foot and even though I bought the 12 and NOT the 12W there is plenty of width. Very comfortable boot. I have put this pair through about 1000 miles mostly on asphalt, ice and snow. Very little actual dirt/ rocky trails. I bought them for the waterproofness and ankle support. Now the soles are getting thin and I can feel small rocks through the soles. Plus the soles are beginning to separate from the uppers and they are no longer waterproof. Not bad for 1000 miles. Still, I feel For a $55 boot they are a good value. I am 6ft and weigh 250.

Worth Every Penny!
Size: 9, Color: Coyote
I absolutely love these boots! They are super light, comfortable and definitely waterproof. I took them on a camping trip for the weekend and I walked through creeks and puddles with no issues at all. No water got inside and they were comfortable all weekend. The only thing was the tongue did start to bother me a bit after the 3rd day. I have some pretty boney shins but a small cloth between my shins and the tongue helped a lot.

Value!

Excellent boot for the price! Very solid. Cushy insoles very comfortable. Wide width plenty wide.
Recommend getting half to full size smaller than your usual.
