Quality!

Came on time and in good condition, communicated well

Purchased a cold air intake for my lb7 very pleased with performance and sound just wish the air box quality was a little better for the price.

Great products, high quality hardware, and very nice powder coating!! Top Notch company

Prefect for and finish!

Amazing customer service. Never experienced a group of people more concerned about the quality, and guarantee of their product.

love chris. makes it easy to get a order through and how i want it

Fast delivery, worked with me on the boot issue from the hot side on the turbo. Not impressed with some of the powder coating. Had a few scratches in it when I received it.

I usually have a good experience. Parts quality is great. Customer service is also great.

Love doing business with ya'll!

Everything was well packaged and beautifully assembled. If it doesn't already, HSP should stand for Hot Sh!+ Part!!highly recommended.

Can’t wait for more products to come out for my truck!

Good communication, good shipped. Product took a while to get.

Thank you

Could not recommend the HSP team and their products more. The team at HSP took great care of me, making sure I got exactly what I needed for my LBZ Duramax. I will be shopping here again for sure.

You guys are so awesome I do love my hsp parts

Had an awesome experience using HSP diesel high flow kit for my lml, everything fit and looked great.

would purchase from this seller again. THX

No hot side bottom elbow. No instructions telling to save your original factory one. Nothing had a thread chaser ran through it. Multiple things need to be re tapped. Balance covers need a place to pry from in case they need to be removed( as mine did due to a faulty injector.
