Sinister Diesel Cold Air Intake for 2013–2018 Ram 6.7L Cummins (Not 2019+)
Bring a reusable filter and a distinctive Sinister Blue finish to your Cummins intake upgrade. This Sinister Diesel cold air intake combines CNC mandrel-bent aluminum tubing, silicone couplers and an oversized cotton-media filter for 2013–2018 Ram 2500 and 3500 trucks with the 6.7L Cummins diesel engine.
Whether your truck handles daily driving or towing duties, the drop-in design and included installation hardware make it a practical upgrade to plan with basic hand tools.
