Whether you're looking for your next upgrade in your series of performance parts, our you're just starting out, this Performance Intercooler Kit for your LML Duramax is a must have. Mishimoto designed this Intercooler Kit to seriously out perform stock; complete with an intercooler, and hot/cold side pipe and boots to increase the performance and reliability of your rig.Adding dense, charged air to your engine is the go-to for performance gains, but chances are your stock intercooler and it's connecting pipes and boots are just not cutting it. If you've made any serious upgrade or if you're just starting to look for potential upgradesa new intercooler is a must. And Mishimoto is the only option for performance intercoolers.
This complete kit from Mishimoto includes not just an intercooler, but both the hot and cold side pipes and boots. This means a total upgrade of your intercooler system for some big gains in power, engine longevity, airflow, and lower EGTs.
Made from durable cast aluminum, the Intercooler is precision engineered with a proven and efficient bar-and-plate core. This design helps to improve airflow, lower intake temperatures, and give you improved EGTs. The Mishimoto intercooler has a 101% increased core volume and is 73% thicker than a factory Duramax intercooler. Both the hot and cold side pipes are made from large diameter mandrel bent aluminum, that dwarfs the stock plastic tubes. All the boots are silicone and made using Mashimoto's DuraCore technology where the innermost layer is a synthetic that outlasts traditional silicone hose. DuraCore helps protect the boots from heat, pressure, fuel, and oil preventing leaks and blowouts. Lastly, the kit comes with high quality T-bolt clamps for superior, lasting hold.
Available in either Sleek Silver or Stealth Black, this USA made--lifetime warranty intercooler is a must have.

Just basted together
Color: Orange, Size: 30, Color: Orange, Size: 30
At first, I was super excited and thought it was a fantastic deal. I bought this suit for a work event, and got it a few days early. I tried it on, everything fit well, I loved the fabric, nothing was tight at all but neither was it loose.
Then, I wear it to work. I even took a picture before heading off to work, where everything was still perfectly out together and no issues were visible. And then I sit down at work to eat my breakfast, and notice that stitching RIGHT OVER MY CROTCH had come loose and made a hole. Not popped, the stitching was not broken or anything, but just unraveled. Nothing was tight, and sitting down and walking felt normal so I know I didn’t strain the fabric at all. The stitches were just loose, and the thread was all over the place.
Luckily I don’t think anyone saw, I was able to keep my legs crossed or cover the problem area strategically with my water jug or bag. But my house is an hour’s drive away from my work, so I couldn’t just go back and change. I had to borrow a stapler and STAPLE THE HOLE SHUT. Yes, lesson learned, I bought several emergency sewing kits that I will stuff in everything I carry with me everywhere in case something like this happens again, but still. It was BRAND NEW.
Not only that, but as I was in the restroom stapling my new suit pants back together, I found the issue. The crotch area was just basted together, no backstitch or proper finishing at all. And it continues down the leg, I had to be careful not to bend my legs too much or those seams would also unravel. They already loosened a little bit and risked showing my skin underneath just by walking.
I managed to play it off and keep my body posed in such a way that it was unnoticeable, especially with help of the staples, but still! Super embarrassing, especially since I’m in a large training class right now and everyone found out just because I had to ask everyone if they had a sewing kit on them. I was so ready to chock this up as a win, too. Good thing I postponed my review.
Sloppy sewing all around really, once I took a moment after getting home to look closer. Some areas are sewn well and finished properly, but others are still only basted shut or the end of the thread wasn’t anchored at all. I’m going to spend a lot of time re-doing the stitches, because I’m too stubborn to send the piece back and I know how to sew better than whatever machine made this anyway so I don’t wanna waste the fabric. Such a disappointment.

I can’t believe the quality for the money
Color: Hot Pink, Size: 38
I am a suit designer for a better priced menswear brand. I bought this suit for a “day-glo” party, so the expectation was going to be one wearing to a party. I wasn’t expecting much for the money, but the color filled the bill. When I received it, I couldn’t believe how great the construction and quality were. The jacket is fully lined, contrast interior piping, interior double welt pockets on both sides, and the fit was really exceptional. The pant had fully taped interior seams, pick stitched curtained waistband, split back seam (so you can easily gave it altered if you need), interior front closure button and tab, hook and eye and exterior button. Note: no one mentioned this, but the waistband is discretely adjustable like a rental tux, so enables fit for a wider range of sizes. The jacket runs true to size, but the pants have some flexibility and are easily altered, so buy your jacket size… that would be harder to alter.
The only gripe is the buttons are super cheap looking, and white colored (surprised they weren’t dyed to match, given the rest of the quality).. I’ll be changing them out.

Tight Waist - No Stretch or Elastic
Color: Dark Green, Size: 30
Jacket fits pretty great, but the pants have zero stretch at all in the waist since there’s no elastic. The pants also fit pretty high waisted so you do get a fold across the front near the pocket/groin area due to the longer inseam. For the price it’s a good deal, but I have ordered this brand with an elastic waist in the same size and it makes a huge difference in the fit and look. For a little more money, I highly recommend their other suits with the elastic waist band!

Very stylish & tailored fit
Size: Small, Color: Pink
My husband purchased this suit as a “flower-bro” at my sister’s wedding. Unfortunately the color theme for the wedding was changed so he had to change it out which I was sad about because it fit him very well and looked great! The quality was good and the fit looked tailored.
