The two-piece design lets you weld the bottom portion to your charge pipe, then thread the HKS-pattern top piece on, with the ability to swap to a different BOV brand later by changing the top piece (HKS or GReddy compatible).\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eWelding a BOV flange directly to a charge pipe is the standard approach, but it locks you into one BOV pattern forever. The ISR modular flange splits that into two pieces: weld the bottom portion to the pipe (which is easier to weld because the top piece comes off), then thread the BOV-specific top piece on. Want to switch from HKS to GReddy later? Unscrew the top piece and replace it with the GReddy variant - no rewelding required.\u003c\/p\u003e\n\n\u003ch3\u003eHKS-Style BOV Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis flange ships configured for HKS-style BOVs. The top portion can be swapped for a GReddy-style top piece (sold separately) to convert between HKS and GReddy BOVs without rewelding the bottom flange to the pipe.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Two-Piece Matters for Welding\u003c\/h3\u003e\n\u003cp\u003eSingle-piece BOV flanges are awkward to weld because the BOV-pattern face is sensitive to heat warping. With the two-piece design, you weld only the simpler bottom flange to the pipe, then thread the precision BOV face on once welding is done. Cleaner welds, fewer heat warp issues, and a flat sealing surface.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal application for charge pipe BOV installation\u003c\/li\u003e\n\u003cli\u003eHKS-style BOVs (top piece swappable for GReddy compatibility - sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x ISR Performance aluminum modular BOV flange (two pieces - weld-on bottom + HKS-pattern top)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-FLA-002\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Modular Aluminum BOV Flange (Weld-On)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBOV Pattern (as shipped):\u003c\/strong\u003e HKS style\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eConvertible To:\u003c\/strong\u003e GReddy style (top piece sold separately)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eDesign:\u003c\/strong\u003e Two-piece - weld-on bottom + threaded top\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBenefit:\u003c\/strong\u003e Swap BOV brands later by changing top piece, no rewelding required\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Universal charge pipe \/ hotpipe BOV installation\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Complete two-piece flange (HKS configuration)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957124358341,"sku":"IS-FLA-002","price":27.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/HKSflangenew_93374_zoom_60491.1399297086.1280.1280__59674.1434036414.1280.1280__77173.1630073044.500.659.jpg?v=1773346646","url":"https:\/\/www.isrcompetition.com\/products\/isr-performance-aluminum-modular-bov-flange-hks-style-bovs","provider":"ISR Competition","version":"1.0","type":"link"}
