Cold Air Intake Systems

Why Does Your Diesel Need a Cold Air Intake System?

The Factory Intake Was Engineered for Quiet, Not Flow

Stock airboxes and intake piping balance flow against noise regulations, manufacturing cost, and emissions test conditions. The result is corrugated ducting, restrictive resonators, and muffling chambers that tame the intake note at the expense of charge density. On a truck that works for a living, that engineering compromise leaves spool and EGT headroom on the table.

Hot Underhood Air Costs Real Power

Denser air carries more oxygen, and the underhood temps a diesel generates while towing can thin the charge measurably. A cold air intake system relocates the filter to draw cooler air and smooths the path through mandrel-bent aluminum piping, so the turbo inhales a denser charge. The math is unforgiving: every degree matters when you are already near the edge on a long grade.

Stock Paper Filters Choke as They Load

A factory paper filter flows fine on day one and declines from there, while high-flow filters sustain airflow as they load. The catch is filtration quality, which is why our kits pair the piping with filters engineered for flow without feeding the turbo grit. Sealed designs keep underhood heat and dirt out; oiled media offers maximum flow for owners who maintain them properly.

What Can a Cold Air Intake System Solve?

Complete Intake Systems Replace the Whole Filter Side

The cold air intake kits in this collection replace the factory airbox, ducting, and resonators with mandrel-bent aluminum piping, a high-flow filter, 5-ply silicone couplers, and stainless T-bolt clamps. Coverage spans the 7.3 Powerstroke through the 2020-2026 6.7, and the 6.7 Cummins Ram, each matched to its generation's engine bay so the piping routes like a factory part.

High Flow Elbows and Horns Open the Engine Side

Past the turbo, the factory intake elbows and horns choke the charge path on every platform. Our CNC-machined 6061-T6 billet aluminum elbows, mandrel-bent tubes with precision TIG welds, and Y-bridge kits for the Duramax, plus turbo inlet horns for the L5P and high flow manifolds for the Cummins, clear those restrictions so the whole circuit flows.

Supporting Ducting, Hoses, and Intercooler Plumbing

Replacement intake hoses and resonator ducts restore cracked or oil-soaked factory pieces, and the intercooler boots, clamps, and cold-side pipes keep the charge circuit sealed under boost. An intake system is a chain from filter to intake ports, and this collection stocks every link.

FAQs About Cold Air Intake Systems

What does a cold air intake system do for a diesel?

A cold air intake system replaces the factory airbox and ducting with smooth mandrel-bent piping and a high-flow filter that draws cooler, denser air from outside the engine bay. Denser charge air carries more oxygen, so combustion runs stronger, and the turbo spools with less effort.

Owners notice quicker throttle response, a more aggressive intake note, and on tuned trucks, support for the extra fuel the calibration adds. It is the intake-side foundation every other airflow upgrade builds on.

Is a cold air intake worth it on a diesel truck?

Honest answer: it depends where your truck is in its build. On a stock engine, the factory airbox flows enough for the stock turbo, so the gains are modest, mostly sound and throttle feel. The forums are full of owners saying exactly that, and they are right for a stock truck.

Once you add tuning, or a bigger turbo, or you tow heavy in hot climates, the intake side becomes a real restriction and a proper system earns its place. Our rule of thumb from two decades of builds: fix the filter side when the engine starts asking for more air than the stock box can hand it.

What is included in a cold air intake kit?

The complete kits in this collection ship as full systems: mandrel-bent aluminum intake piping sized to the application, the high-flow filter, mounting hardware, 5-ply silicone couplers, and stainless T-bolt clamps. Some applications include heat shielding or a sealed enclosure to keep underhood heat out of the charge.

Everything needed to pull the factory hardware and install the system comes in the box, so the swap happens in the driveway with basic hand tools instead of piecing together pipes, couplers, and clamps from three vendors.

Which cold air intake fits my truck?

Match the kit to your engine generation. Ford coverage runs the 7.3 Powerstroke (1999.5-2003), the 6.0 (2003-2007), the 6.4 (2008-2010), and the 6.7 Powerstroke split into 2011-2016, 2017-2019, and 2020-2026 generations. Ram coverage handles the 6.7 Cummins from 2007.5-2012.

The Duramax side of this collection focuses on the engine-side upgrades instead: high flow intake elbows and Y-bridge kits from the LLY through the LML, and turbo intake horns for the L5P. Send us your year and engine if the fitment is unclear, and our support team will confirm before anything ships.

Oiled or dry filter: which should I choose?

Oiled cotton gauze media flows the most air and is what our oiled-filter kits use; the trade-off is maintenance, because the filter needs cleaning and re-oiling on schedule, and an over-oiled filter can coat a mass air sensor. Owners who stay on top of maintenance love them.

Dry media filters trade a small amount of flow for zero-mess upkeep: just wash, dry, and reinstall. If you are the type to service the truck on schedule either way, the oiled kits in this collection give you everything the media can offer.

Do I need a tune with a cold air intake?

No. Cold air intakes are bolt-on hardware that the engine calibration handles without changes, and no codes appear from the swap. Install it, check the couplers, and drive.

Where tuning enters the picture is getting the most from the intake. On a tuned truck, the calibration was already written for increased airflow, so the intake simply delivers what the tune expects. On a stock truck, the intake works fine alone; the tune is a separate decision.

What is the difference between a cold air intake and a high flow intake elbow?

They work on opposite sides of the turbo. The cold air intake handles the suction side, drawing air from outside the engine bay through the filter and into the turbo inlet. The high-flow intake elbow, horn, or manifold handles the charge side, carrying compressed air from the intercooler into the intake ports.

Both sides have factory restrictions, and the biggest gains come from clearing both. That is why this collection stocks the filter-side systems for the Ford and Ram platforms and the engine-side elbows, horns, and Y-bridges for the Duramax and Cummins crowd.

How hard is it to install a cold air intake?

It is one of the easiest upgrades on a diesel. Remove the factory airbox and ducting, assemble the new piping with the supplied couplers and clamps, seat the filter, and confirm the intake tract is sealed. Most installs run 30 to 60 minutes with basic hand tools.

The generation-specific kits route like factory parts, so nothing needs fabrication. The one detail worth double-checking is coupler alignment and clamp torque, because an intake leak on a diesel shows up as a whistle and a smoke tune nobody asked for.

Will a cold air intake lower EGTs when towing?

On its own, expect modest gains; a couple of degrees of charge density helps, but the stock airbox was not the biggest EGT problem on most trucks. Where intake work pays off on EGTs is as part of the full airflow chain: intake feeding the turbo, high flow elbow or manifold behind it, and a free-flowing exhaust letting it all out.

Towing-heavy trucks see the clearest benefit, holding speed on grades with less throttle and lower sustained EGTs than the restricted factory plumbing allowed. Our support team can sequence a full airflow build for your platform if EGTs are the mission.

Are cold air intake systems street legal?

Intake systems are emissions-neutral airflow hardware, not emissions controls, so they remain street legal in most jurisdictions; California requires CARB-exempt status for intake modifications on some applications, so check your local requirements. That makes intakes very different from the delete upgrades elsewhere in our catalog, which are sold for competition and closed-course off-road use only.
