HSP Diesel

Great products, great service, love my intake and my custom powder coating color was perfect

The traction bars make a world of difference on my 08 duramax the quality is amazing and instalation was pretty straight forward.

Ive installed 2 max air flow bundles one on an lb7 and one on an lbz both were easy to install and made the engine bays look clean both made performance leaps and bounds better over stock!!!

I have the HSP Y-Bridge kit and Hot/Cold side intercooler pipes. Great upgrade! Easy install and great quality! Highly recommend!

Love your product
