Collection: Duramax Intercooler

Good fit, sounds awesome, definitely made a difference, hose clamps could be a little better, holes was off a little for the sensors, but for the price overall good product!

They have great customer service what I order was much better than what I was expecting to receive thank you for guys for everything

This was a very easy install, the parts seems to be good quality.

Great products, the updates and revisions to there parts show they care about making things better. 100% would buy all my parts from Spelab.

Directions were not good and there isn’t a heater bolt yet..but the product is great and you can’t beat the price. Happy with the product.

This is a good upgrade. I change the rear differential fluid frequently so now I will be able to drain and refill more easily. Easy install. No leaking. Hardware and gasket included. Very happy

I was impressed with the build quality. And very happy with the cover features: fill plug, drain plug, sight glass, nice paint, cooling fins and machined channels on the inside to direct fluid flow. I also put in some AMSOIL diff fluid. A winning combo. Love that gasket and premium hardware is included. A much better deal than the Banks cover. This cover will cool plenty abd direct fluids where it needs to go. I’m happy with my investment and highly recommend.

Fairly straight forward to install. My truck seems to be running and breathing a ton better.

Installed this billet version onto my 2019 Roush F150 recently. I wanted a cover that had the proper fluid flow vaning and fill and drain plugs to make future fluid changes easier, as I plan to renew the fluid every 30k miles. The sight glass so you can see the level and the condition of the fluid is also a great feature. I did quite a bit of research on which cover I wanted to install and saw the fluid flow issues with the square back covers, whereas this one has the proper curved design and vanes in it to direct the fluid that's coming over the top to the correct places of the differential for proper lubrication. I went with the billet one so that it's stronger than the lower priced cast version, as I keep my vehicles forever (20 years and 200k miles or more) and would rather do it right one time than have to do it again. The magnetic plugs to capture any ferrous gear wear is also a nice benefit. Installed with LubeLocker gasket.

Fit like crap. As did the down pipe. I got ppe ones and no refund from spelab

Fits very well and is really well constructed. Also looks really good installed in the truck!

Fit, "Like a glove!"

Didn’t have an issue with the install. Instructions weren’t real clear but overall the install was easy. Parts seemed to be good quality.

Fit nice and looks great!

I love it wish I had a tuner for my truck now, but I love it thank you
