Snow Performance has combined performance, quality, and ease of installation in this new water-methanol injection kit designed for all Chevy / GMC LBZ / LLY/ LMM/ LML / L5P Duramax Ford owners who demand colder EGTs while towing heavy loads. The Diesel Stage 3 Boost Cooler utilizes a 2D mapped controller that commands injection based on boost pressure and EGTs (exhaust gas temperatures) to maintain extremely cold air inlet temperatures, 100-300 EGT decreases, decreased emissions, cleaner engine components, and increased fuel economy all while giving 65+ HP to help pull large hills with easy effort while towing. A must have for the diesel enthusiast that is concerned about the longevity of his truck that sees heavy towing. None invasive, the Diesel Stage 3 Boost Cooler controller is designed to mount on the steering column or the dash so no drilling/marring of the interior needs to take place or additional gauge pods need to be purchased. Functions as a boost gauge, water-meth controller and EGT monitor all in one! Concerned about warranty? The Snow Performance Stage 3 does not leave a signature on the vehicle leaving your diesel truck with its warranty intact. 7 Gal Tank included for trip ready installation. Recommended for all daily driven Chevy /GMC LBZ / LLY / LMM / LML / L5P Duramax owners that see heavy towing where EGTs become dangerously high. Need a CARB E.O.# for your state? No problem!

Fine but not great
It fit well and looked ok. However the material was thinner and flimsier than I expected. It was quite wrinkled and I couldn’t iron it well without risking melting it due to the polyester content. After ironing for about an hour on low heat it was passable but it was a lot of work to only get a passable result.

El traje me gusto lo pedí en size 8 y le quedó grande a mi hijo, lo volví a pedir en un size 7 y lo q me entregaron fue una mercansia usada llena de brillo y mal olor, desde q abrí el paquete se veía q esta usada, me parece de muy mal profesionalismo ya q deberían revisar las cosas de devuelven para q después clientes como yo no tengamos q pasar por esto

Definitely Worth It!

Love this set for my little Easter-man (Khaki - Size 6)! I have a husky 5 year old son. ( I was able to hem the pants myself although his pants slipped down a bit before I tightened his belt) Loved the overall quality for the price! Kids play - it was the perfect material to give a good look but not break the bank. I purposely bought a bit large to ensure he’ll be able to wear it longer. I’ll be back for the navy suit. SN: Mom’s dress is from Amazon, Little sister’s dress is from Costco

Exceptional boys suit!
Size: 12, Color: Light Blue, Size: 12, Color: Light Blue
Seriously Great Little Suit! True to Size and Looked So Sharp. I bought this blue suit in a size 12 for my son, and honestly, I was really impressed. You know how sometimes kids' clothes sizing is all over the place? Well, this suit was actually a true size 12, which was a huge relief. It fit him perfectly right out of the box. And the best part? It looked fantastic on him! The blue is a really nice color, and the suit just looked really well-made. He wore it to a 6th Grade graduation and he looked so grown-up and handsome. We got a ton of compliments. If you need a good-looking suit for your son that actually fits, you should definitely check this one out. We were really happy with it!
