{"product_id":"s65-modular-carbon-plenum","title":"S65 Modular Carbon Plenum","description":"\u003cp\u003eA complete redesign of the OEM S65 plenum, bringing more than just a carbon copy of the original — much like Infinity Design's acclaimed S85 plenum. With a 1.2 mm wall thickness, it unleashes the full S65 soundtrack while adding increased volume at the top frontal section and top cover.\u003c\/p\u003e\u003cp\u003eThe system is fully modular, allowing different lids and velocity stacks to be fitted. The supplied carbon velocity stacks are larger than OEM with a bigger opening, and CNC throttle-body connectors are included.\u003c\/p\u003e\u003ch3\u003ePerformance Testing\u003c\/h3\u003e\u003cp\u003eDyno tests were performed under strict controlled conditions on an independent Dynojet, with Infinity Design's high-flow intake already fitted so both plenums performed at their best. The OEM plenum produced 340–343 hp; after fitting the carbon plenum the same car made 349–350 hp — gains of 5–8 hp through 5600–6400 rpm and 8–10 hp through 6800–8200 rpm.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e+5–10 hp (dyno-verified)\u003c\/li\u003e\n\u003cli\u003e100% pre-preg carbon fibre, 1.2 mm wall thickness\u003c\/li\u003e\n\u003cli\u003eModular design with interchangeable lids and velocity stacks\u003c\/li\u003e\n\u003cli\u003eLarger-than-OEM carbon velocity stacks\u003c\/li\u003e\n\u003cli\u003eCNC throttle-body connectors\u003c\/li\u003e\n\u003cli\u003eNo ECU tuning required; dramatically enhanced induction sound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 × Carbon Plenum (lid and main body)\u003c\/li\u003e\n\u003cli\u003e10 × Larger Velocity Stacks\u003c\/li\u003e\n\u003cli\u003e10 × CNC Throttle Body Bosses\u003c\/li\u003e\n\u003cli\u003eNuts and bolts\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Infinity Design","offers":[{"title":"Gloss","offer_id":49607479918730,"sku":"INF-S65-P-G","price":3511.0,"currency_code":"NZD","in_stock":false},{"title":"Matte","offer_id":49607479951498,"sku":"INF-S65-P-M","price":3511.0,"currency_code":"NZD","in_stock":false},{"title":"Chequered Gloss","offer_id":49607479984266,"sku":"INF-S65-P-CH","price":3804.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4599\/4122\/files\/Infinity_Design_S65_Carbon_Plenum_Exploded.jpg?v=1782661004","url":"https:\/\/qjipdu-tf.myshopify.com\/products\/s65-modular-carbon-plenum","provider":"SBX Performance","version":"1.0","type":"link"}
