This is a complete replacement for the factory plastic piping that carries turbo air to the intercooler and back to the engine. The kit includes four aluminum pipes and six silicone boots, so both the hot side (before cooling) and cold side (after cooling) get replaced in one purchase.
why this one — Doing the whole piping system at once means you are not chasing failures pipe by pipe later. Mishimoto claims the larger diameter cuts restriction and lowers exhaust gas temps, but again publishes no dyno number, so this is best framed as a reliability and airflow upgrade rather than a specific horsepower promise. Current price is on sale from $803.00.
Mishimoto claims the larger-diameter mandrel-bent pipes provide "a significant increase in airflow that results in more power and lower EGTs" versus the restrictive factory piping, but publishes no specific HP/TQ number. source ↗
