The aFe BladeRunner front-mount intercooler 46-20424-B is engineered to deliver a bar-and-plate or tube-and-fin core that delivers significantly lower intercooler outlet temperatures than the factory unit at equivalent boost levels for the 2020-2021 Chevrolet Silverado 1500. Built from stainless steel and finished in black, the 46-20424-B is a direct bolt-on replacement for the factory system with no cutting or welding required. Cooler charge air means denser air entering the cylinders, which the engine converts directly into more consistent power output throughout the boost range. The 46-20424-B is an essential upgrade for any turbocharged build that is making more boost or more power than the factory intercooler was designed to support.

A charge pipe kit alone typically does not require a tune. A full front-mount intercooler upgrade on a heavily modified engine may benefit from a tune to take full advantage of the cooler charge temps. Consult your tuner when building a complete power package.
Can this intercooler handle increased boost pressure from an upgraded turbo?Yes. The aFe BladeRunner front-mount intercooler is designed to support power levels well above the factory target. For extreme applications, verify core sizing matches your target power level and contact aFe Power for platform-specific guidance.
Will installation affect my factory boost control or DTC codes?No, provided all factory sensor ports are properly transferred or replicated in the new piping. The 46-20424-B is designed to retain all OEM sensor locations. Follow the installation instructions carefully to avoid boost leaks that can trigger fault codes.
How do I check for boost leaks after installation?After installation, use a boost leak tester (pressurized air at low PSI through the intake) with the engine off to listen or feel for any leaks at all coupler joints. Fix any leaks before driving under boost.
Is this compatible with stock turbo upgrades or supporting mods?Yes. The 46-20424-B is designed as a bolt-on replacement within the OEM chassis envelope. It is compatible with stock turbos and most popular turbo upgrade kits for the 2020-2021 Chevrolet Silverado 1500. Confirm any dimensional clearances specific to larger turbo compressor housings before ordering.
Does this void my factory warranty?Under the Magnuson-Moss Warranty Act, a dealer must demonstrate a direct causal link between this modification and any specific failure to deny a warranty claim. However, on vehicles under factory powertrain warranty, consult your dealer before installing forced induction components.
What maintenance is required on aluminum intercooler piping?Inspect the coupler joints and clamps annually or after any hard boost session. Re-torque any clamps that show signs of movement. The powder coat finish is durable but can chip if impacted, so touch up exposed aluminum to prevent oxidation in high-salt environments.
What is the warranty on this product?aFe Power provides a limited manufacturer warranty on BladeRunner intercooler systems covering defects in materials and workmanship. Coverage does not include damage from improper installation, boost leaks, or use beyond the rated pressure range. Contact us for full warranty documentation.

Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...

Intercooler components let you build, upgrade, or repair your charge cooling system without replacing the entire intercooler assembly. Quality piping, silicone couplers, mounting brackets, and core upgrades make a meaningful difference in keeping intake temperatures low on high-boost builds and daily-driven turbocharged vehicles alike. Popular Upgrades Frequently ordered intercooler components include upgraded silicone coupler hose kits to replace cracked or blow-off-prone rubber hoses, intercooler core upgrades for higher bar-and-plate or tube-and-fin density, aluminum intercooler piping sets that replace restrictive OEM plastic pipes, and universal mounting brackets for custom intercooler positioning on fabricated builds. What causes intercooler components to fail? The most common intercooler component failure points are silicone or rubber couplers that crack or split under repeated heat cycling, plastic OEM piping that becomes brittle over time, and mounting brackets that fatigue...

An intercooler is the single most important component in a turbocharged induction system for supporting power gains from higher boost. By cooling compressed air before it enters the engine, an upgraded intercooler delivers denser, cooler charge air that allows more fuel to be safely injected and combusted, directly translating to more horsepower and torque. Popular Upgrades Best-selling intercooler upgrades include front-mount bar-and-plate aluminum intercoolers for Subaru WRX and STI, Mitsubishi Evo, and Volkswagen GTI platforms, direct-fit top-mount intercooler upgrades for rotary and compact turbo applications, and heavy-duty intercooler upgrades for Ford Powerstroke and Dodge Cummins diesel trucks where factory coolers are prone to failure under load. What is the difference between bar-and-plate and tube-and-fin intercoolers? Bar-and-plate intercoolers use a stacked aluminum plate construction that is more durable and provides superior cooling efficiency but adds more weight. Tu...
View Intercoolers ProductsLooks pretty nice, pricing was good and the reinforcement is a big plus.
I emailed customer service to inquire about when it would be shipped. They checked and emailed me with the answer. Customer service is A1
Installation was easy. The price is good and it looks great on the truck.
Looks as good as it fits,
I love it great sound and response
Car totally diferent with the whole kit. Ive stood next to wide bodies and my car gets more attention at times . Ive bought the kit twice already.
Fantastic emblem! Exactly what I was looking for. Great quality emblem.
Worked great for my aftermarket hood on my Chrysler 2023 300C. Thanks
Easy to install and makes car sound even better love the winn
Awesome customer support. Had multiple issues with fedex and these guys were excellent in helping me sort everything out. The drop springs are great too! I highly recommend
100/100! perfect CF crafted cold air intake for 6.4 jeep .. even makes my AWE exhaust sound even deeper and you cam here this thing sucking when accelerating even at normal speeds🥶
