Injen SES Intercooler Pipes - Polished

Polished aluminum charge piping to replace the factory plastic intercooler pipes on the 19-20 Z4 and 2020 Supra. The OE plastic couplers are a known failure point under elevated boost — these are mandrel-bent aluminum with reinforced silicone connections. Smoother internal transitions reduce pressure drop between the intercooler and throttle body. Not CARB legal.
