HSP Diesel 2020-2024 L5P Duramax Cold Air Intake: Advanced Performance Design The HSP Diesel 2020-2024 L5P Duramax Cold Air Intake stands out as our most advanced design to date. Featuring smooth 4.5IN mandrel bends and HSP's innovative MEGA filter, it delivers consistently cool air to your Duramax engine with greater efficiency than the stock intake. Santoprene TPV inserts, molded for a secure fit on both the fender and hood, ensure no power escapes before reaching our intake system. The HSP Cold Air Intake demonstrated an impressive 88% flow improvement over stock on our flow bench, enabling your truck to breathe easier. Our engineers achieved significant gains in efficiency and volume while retaining factory MAF calibration, making this a true bolt-on upgrade that requires zero tuning.
