Mishimoto Performance Intercooler; Silver (17-19 6.6L Duramax Silverado 3500 HD)Find parts that fit my vehicle

Good Buy

Took just a bit over an hour, only due to hose clamps on the hot side not being properly aligned. Spent a good 30 minutes fighting terrible angles to access those hose clamps. Do yourself a favor and align all hose clamps on every car you own, so it's conducive to easier work. And then tell all your friends and neighbors to do the same. This unit is substantially larger than the stock one, and the cooler temps absolutely reflect it. I am not tuned, and as to be expected no "noticeable" whp gains were made. However, I AM maintaining boost FAR better. Heatsoak is practically non-existent, and I am consistently making 17psi through 5+ pulls even after an hour of driving, which is certainly the major benefit! I will update after a tune if any improvements were made.

Good upgrade

This was a good upgrade. Straightforward install and the video was a good reference. High quality part and most of the factory pieces fit snug. The grommets I added a small amount of grease to keep them from falling off. Very happy with this product Took hour and a half to install the only thing I had a issue with was the plastic shroud was hard to get started but once I got a corner the rest was easy

Huge Difference!

Super easy install probably 30mins roughly. Installed on a 2020 F150 limited. I didn’t realize my truck had no IC fan like the raptors so it made fitment even quicker. Large area for cooling excellent material, no heat soak, consistent boost. While you’re changing out the IC you might as well throw on a new BOV imo..

Worth the money

This intercooler completely changed the performance of my truck. So much more power.

New Mishi

Arrived quickly, easy install, great quality! So far so good, been on a couple days now.

Great mod

Fit well, can fell the turbos pulling better, will test at track soon

Fast spool ups

Definitely feel the difference in turbo response time and get someone to help you. A jack made it annoying trying to wiggle it around

HP

Horsepower isn't cheap! Thankful for American Truck for the affordability and availability of parts!

Great intercooler

Had this put in along with their racing radiator, was having problems over heating when pulling a load, especially when turbos was boosting high! No overheating problems now. Would buy again! Great products!

Worth the money

During the summer months I pull a 30 ft travel trailer and on hot days my engine tends to hot so I purchased this to replace and upgrade the smaller and inferior OEM intercooler. Time will tell when we roll into summer and I’ll check back in but out of the gate I noticed a improvement in performance and power (with no load kind you) when I did the first road test after completing the easy installation that took about an 1.5 hours including cleaning the garage floor before and after. Fitment was perfect (must remove the OEM upper support), air dams are a good tight fit. Very well designed and engineered.
