K&N Engineering

K&N is best known for reusable air filters and cold air intakes, and it also builds aluminum charge pipe kits for turbocharged trucks and SUVs. Shop K&N charge pipe kits that replace restrictive factory intercooler piping on the Ram 2500 and 3500 6.7L Cummins, Chevrolet Silverado 2500 and 3500 HD 6.6L Duramax, Ford Super Duty, Ford Bronco and Bronco Raptor, Toyota Tacoma 2.4L turbo, and more, plus a K&N boost control module. Each kit is built for a specific vehicle and engine, so confirm your application before ordering. K&N charge pipes in this collection are for off-road and competition use.

Who is K&N Engineering?

K&N was founded in 1969 by Ken Johnson and Norm McDonald, whose initials form the company name. It's known worldwide for washable, reusable air filters and cold air intake systems. K&N's charge pipe kits extend that airflow focus to the boosted side of turbocharged engines.

What K&N parts do we carry?

Charge pipe kits. Mandrel-bent aluminum pipes that replace restrictive factory intercooler piping on specific turbocharged vehicles, finished in gunmetal gray powder coat. Many include a port that can accommodate a water-methanol or nitrous injection kit. Applications include:

Ram 2500 and 3500 6.7L Cummins
Chevrolet Silverado 2500 and 3500 HD 6.6L Duramax (2020 and later)
Ford F-250 and F-350 Super Duty 6.7L Power Stroke
Ford Bronco 2.7L EcoBoost and Bronco Raptor 3.0L EcoBoost
Toyota Tacoma 2.4L turbo

Why replace factory intercooler piping?

Factory charge piping on many modern turbo trucks and SUVs uses plastic sections and rubber couplers. Under boost and heat, especially when towing, those parts can crack or slip off, causing a sudden loss of boost. A mandrel-bent aluminum pipe keeps a consistent inside diameter through every bend and holds up better to boost and heat.

On a stock vehicle, the main benefit is reliability. On a tuned vehicle, a smoother, less restrictive pipe can also reduce pressure loss between the turbo and the engine.

How do I choose the right K&N charge pipe?

Match the exact vehicle and engine. Kits are built for specific engines. A Bronco 2.7L pipe won't fit a Bronco Raptor 3.0L.
Plan for injection. If you're adding water-methanol or nitrous, a kit with an injection port saves fabrication work.
Pair with an intake. K&N intakes and charge pipes are designed as separate upgrades that can work together on many vehicles.
Check California rules. K&N notes that some charge pipes are not legal for sale or use in California on pollution-controlled vehicles.

Installation notes

Allow about an hour for most kits, with common hand tools.
Clean the system if a factory pipe failed or a turbo was replaced.
Seat couplers and clamps fully, and reconnect any sensors on the factory piping.
Pressure-test the system before driving, and recheck clamps after a few heat cycles.
Plug the injection port if you're not using it.

Common problems K&N parts address

Cracked or blown-off factory charge pipes on turbo trucks and SUVs.

Boost leaks when towing that cause low boost and power loss.

Restrictive factory piping on tuned vehicles.

Frequently Asked Questions

K&N questions usually come down to fitment, what a charge pipe replaces, and legality. The answers below cover charge pipes versus intakes, injection ports, tuning, and California rules. Confirm fitment for your exact vehicle on each product page, and contact our team for help.

What does a K&N charge pipe replace?

The factory intercooler piping between the turbo, intercooler, and engine.

Is a charge pipe the same as a cold air intake?

No. An intake feeds air into the turbo. A charge pipe carries boosted air after the turbo.

Can I add water-methanol or nitrous with a K&N charge pipe?

Many K&N charge pipes include a port that can accommodate a water-methanol or nitrous injection kit.

Do I need a tune for a K&N charge pipe?

Typically no. Charge pipes commonly work with the factory calibration.
