aFe GM Colorado/Canyon 2.8L Hot/Cold Pipes Red 16–20

BladeRunner charge piping for the exact engine

The aFe 46-20264-R is the red hot and cold-side aluminum charge-pipe kit for 2016–2020 Chevrolet Colorado and GMC Canyon 2.8L LWN turbo-diesel applications. It uses 2.5-inch hot / 3-inch cold mandrel-bent aluminum tubing, not stainless-steel tubes, and mates to the original intercooler using billet factory-style adapters.

Key Features

• 2.5-inch hot / 3-inch cold aluminum routing with two factory-style billet quick-connect adapters.
• Manufacturer-described five-ply polyester-reinforced silicone couplings and stainless-steel clamps; stainless describes the clamps, not the tubing.
• The current primary page reports 14% more flow than its stock comparison. This is a manufacturer flow-test claim, not a guaranteed horsepower, temperature drop or additive gain with other components.
• One manufacturer-listed 1/8 NPT auxiliary port per tube is supplied with a plug for unused installation. A port is not universal approval for every sensor or water/methanol nozzle.

Fitment

46-20264-R: The current exact primary page and linked manual cover 2016–2020. Broader retailer tables list later years, but those later applications remain a source conflict and are not extended here. The original 2018 Canyon SL row conflicts with GMC diesel availability and is excluded; SLT model detail is retailer-supported within the manufacturer engine/year scope. Other named trims still require actual 2.8L LWN and connection confirmation.

Specifications

What's Included

• Two aluminum charge pipes: one 2.5-inch hot tube and one 3-inch cold tube.
• Four silicone couplings, eight clamps, two O-rings, two plugs and two billet quick-connect adapters, from the two exact hot/cold manual packing lists.
• Hot-side steps identify two #44 clamps, one #32 clamp and a final turbo-end clamp without independently numbering that last clamp. Cold-side steps identify three #44 clamps and one #48 clamp. Do not infer an unlabelled fourth hot-clamp size.
• Reuse the original temperature sensors and metal retaining clips. No new intercooler core, air filter or complete sensor/injection system is supplied.

• Match actual inlet, turbo and intercooler connections. A shared engine size does not approve another model or year.

Frequently Asked Questions

An engine- and year-specific BladeRunner charge-pipe kit, not a complete intercooler, turbocharger or air intake.

is the red hot and cold-side aluminum charge-pipe kit for 2016–2020 Chevrolet Colorado and GMC Canyon 2.8L LWN turbo-diesel applications. It uses 2.5-inch hot / 3-inch cold mandrel-bent aluminum tubing, not stainless-steel tubes, and mates to the original intercooler using billet factory-style adapters.

No. The manufacturer reports side-specific flow comparisons; actual engine power, charge temperature and boost depend on the complete setup.

Reuse the original two temperature sensors and two metal retaining clips. Remove the original plastic clip-retaining housing to recover the clip; lubricate the supplied O-ring lightly. One auxiliary 1/8 NPT port per tube is manufacturer-listed, with an unused-port plug; it does not include an injection system.

Exact manual directs clamp tightening with an 8 mm socket but supplies no numerical torque or mileage interval. Do not apply the stainless OER SmartSeal 72 in-lb value to these clamps.

The original 2018 Canyon SL row conflicts with GMC diesel availability and is excluded; SLT model detail is retailer-supported within the manufacturer engine/year scope.

No. An accessory port does not include or universally approve a controller, nozzle, pump, sensor or injection system. Seal unused ports as instructed.

The current exact manufacturer page and linked manual state this aluminum pipe configuration is not CARB exempt and is unavailable for purchase in California or use on vehicles registered with the California DMV.

Installation Instructions

1. Read the exact manufacturer instructions for 46-20264-R, verify the actual engine, supplied parts and every unresolved source conflict before disassembly.
2. Cool and securely park the vehicle. Disconnect the appropriate original temperature-sensor connectors and release the original turbo/engine-end clamps and intercooler quick connections as shown in the exact manual.
3. Remove the original charge pipes and temperature sensors. Carefully release the plastic housing retaining each original metal clip so that the metal clip can be reused on the supplied adapter.
4. Seal the unused auxiliary port with the supplied plug and thread sealant. Transfer each original temperature sensor into its separate sensor port. Follow the exact hot/cold port orientation; do not substitute an injection nozzle for the original temperature sensor.
5. Lightly lubricate the supplied O-rings, seat them in the adapter grooves and install the original metal clips on the adapters. Assemble the couplings with the manual clamp-number assignments.
6. Fit the intercooler connection first and then the turbo/engine ends. Reconnect all sensor wiring. The hot manual also directs sliding a factory rubber-hose clip to prevent contact with the new hot tube. Ensure the pipes clear metal surfaces and rubber hoses before tightening.
7. Tighten clamps with the instructed 8 mm socket and verify complete seating, retained clips, clearances and secure connections before operation. The exact aluminum manual gives no numerical torque or mileage recheck interval.

46-20264-R: inspect every connection and resolve the documented kit discrepancies before operation.
