Supply your 2004.5-2007 GM 6.6L Duramax LLY/LBZ with improved airflow when you install the HSP LLY/LBZ Cold Air Intake Bundle. Proudly made in the USA, the Cold Air Intake Bundle includes a 4” Intake Tube and HSP’s High Flow Turbo Mouthpiece. The Cold Air Intake Bundle features HSP’s signature Heat Shield Box that blocks hot air from entering the engine.
I realize this was a custom ordered piece and expected to wait for it, but it’s been 6 weeks. Hopefully it will be here soon. Keep that in mind if you are ordering anything that needs powder coated/ HSP. Customer service has been great. They don’t keep these parts in stock. I’ll update this review once it comes.

Mounts right up and looks great. The blood red really pops. The increase of air flow really woke my lly up.
