The hot pipe ships with ISR's modular base flange welded in place and the HKS-style top flange threaded on. Just thread the HKS-style flange on, fit your HKS BOV, and bolt the hot pipe in place of the plain ISR hot pipe.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eAdding a blow-off valve to an existing ISR intercooler kit usually means either (a) cutting and welding a new flange onto your existing hot pipe (which means downtime, fab work, and the risk of warping the pipe) or (b) buying a complete new hot pipe with a flange already welded in. This kit is option B without the price tag, and with one major bonus: because it uses ISR's modular flange design, you can swap between HKS, GReddy, and TiAL BOV styles later by just swapping the threaded top piece, no rewelding required.\u003c\/p\u003e\n\n\u003ch3\u003eFuture-Proof Modular Design\u003c\/h3\u003e\n\u003cp\u003eThe HKS-style flange included here threads onto a universal base flange already welded to the hot pipe. If you decide to switch BOV brands later, buy the alternate top flange (GReddy or TiAL style) from ISR and thread it on. No cutting, no welding, no replacing the hot pipe.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1989-1994 Nissan 240SX (S13) with SR20DET swap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequires the ISR Performance S13 Front Mount Intercooler Kit\u003c\/strong\u003e (this hot pipe is sized to fit that specific kit; it replaces the standard plain hot pipe in the kit)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBOV Sold Separately\u003c\/h3\u003e\n\u003cp\u003eThis listing is the hot pipe and HKS-style flange only.
