ISR Performance Intercooler Hotpipe Kit w/ Tial BOV Flange for Nissan S13 SR20DET

The ISR Performance Intercooler Hotpipe Kit with Tial BOV Flange for the S13 SR20DET is the Tial-flange variant of our SR20DET hotpipe line. 2.25" aluminum hotpipe with a pre-welded threaded flange paired with a threaded Tial BOV flange. Required for any SR20DET intercooler kit setup if you don't already have the factory steel hotpipe, and the threaded flange design means you can swap to a different BOV style later by just ordering a different flange.

What It Does

The hotpipe connects the turbo outlet to the intercooler inlet. If you've removed or lost the factory steel hotpipe (or you're building a new SR20DET swap from scratch), you need a replacement to make any intercooler kit work. The 2.25" aluminum construction matches typical S13 intercooler piping diameter, and the pre-welded threaded flange on the BOV side accepts our Tial 50mm BOV weld-on flange (IS-FLA-007 style geometry). Because the flange is threaded onto the pipe rather than welded, you can swap to a different BOV style later (GReddy, HKS, etc.) by ordering the matching threaded flange.

Fitment

Designed for the Nissan SR20DET swap with the S13 240SX factory-style intercooler kit. Tial 50mm BOV flange variant. pairs with Tial 50mm BOV.
