FORGE boost pipe for Hyundai Kona N

Description

This boost pipe runs from the intercooler outlet to the throttle body (cold side). It is a single-piece mandrel-bent alloy pipe with a 66 mm inner diameter that matches the size of the original throttle body. The inlet bore has increased from 55 mm to 66 mm, which is 20 % larger. In testing, this gave faster spool-up and crisper power delivery.

CNC-machined billet alloy bosses are welded to the pipe, so all the original attachments fit perfectly. The silicone joiners have a fluorosilicone inner liner. The larger diameter increases airflow into the engine, which benefits both performance and efficiency, especially on vehicles running aftermarket software.

A 1/8″ NPT boss for water/methanol or nitrous injection sits directly in front of the throttle body. It helps keep inlet air temperatures lower at high power or in hot climates. Fitting the pipe does not trigger an engine check light.
