Product Description

The aFe 46-20488-R BladeRunner Hot Charge Pipe is a direct-fit aluminum upgrade for the 2021-2024 Toyota GR Supra equipped with the 2.0L Turbo I4 B48 engine. The factory plastic charge pipe on the B48 Supra is a known restriction point - prone to heat soak, deformation under boost, and insufficient flow for tuned applications. The BladeRunner pipe replaces it with a TIG-welded 2-3/4" mandrel-bent aluminum tube that outflows the stock unit by up to 11%, reducing intake air temperatures and improving turbo response.

Installation is straightforward - the pipe uses a factory-style billet aluminum quick-connect adapter with an o-ring seal that mates directly to the OEM intercooler and intake connections without modification. Premium stainless-steel spring-loaded T-bolt clamps and 5-ply silicone couplings provide a boost-proof, leak-free seal at all connection points. The 1/8" NPT port allows for direct mounting of a boost sensor, boost gauge, or water/methanol injection line. Finished in textured red powder coat with a laser-etched aFe POWER logo. Note: this pipe fits the 2.0L B48 engine only - the 3.0L B58 Supra requires a separate part number.
