An additional opening on the right-hand side, away from engine heat, has shown improved performance.\u003c\/p\u003e\u003cp\u003eA bespoke double-cone filter with a 170 mm (6¾\") opening lets the turbo draw in the maximum amount of air, while a single venturi inlet tube smooths the airflow to improve throttle response and increase horsepower and torque. The smoother, less restrictive design also allows faster turbo spool-up and sharper dynamic response.\u003c\/p\u003e\u003cp\u003eThe fully sealed design keeps high-temperature engine-bay air out, holding intake air temperatures at their lowest at all times so the ECU does not pull ignition timing — heatsoak is effectively non-existent. CFD analysis confirmed smooth, non-turbulent airflow across the filter.\u003c\/p\u003e\u003ch3\u003ePerformance Testing\u003c\/h3\u003e\u003cp\u003eDyno tests were performed under strict controlled conditions at one of the UK's most respected Mercedes tuning companies. A Stage 3 car with a larger turbo, downpipe and ECU tune making over 500 hp was used for the comparison, showing a genuine increase of 14–18 hp from 5200–6900 rpm along with earlier turbo spool-up and increased low-end torque.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e+14–18 hp (dyno-verified on a 500 hp Stage 3 car)\u003c\/li\u003e\n\u003cli\u003e100% pre-preg carbon fibre construction\u003c\/li\u003e\n\u003cli\u003eNo ECU tuning required\u003c\/li\u003e\n\u003cli\u003eFully sealed airbox for the lowest intake air temperatures\u003c\/li\u003e\n\u003cli\u003eBespoke 170 mm double-cone high-flow filter\u003c\/li\u003e\n\u003cli\u003eFaster turbo spool-up and improved throttle response\u003c\/li\u003e\n\u003cli\u003eDirect OEM fitment, available in gloss or matte carbon finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 × Venturi Inlet Tubes\u003c\/li\u003e\n\u003cli\u003e1 × Frontal Dual Inlet Duct\u003c\/li\u003e\n\u003cli\u003e1 × Carbon Wiring Loom Cover\u003c\/li\u003e\n\u003cli\u003e1 × Bespoke Infinity Design Air Filters\u003c\/li\u003e\n\u003cli\u003e1 × Black metal clamps\u003c\/li\u003e\n\u003cli\u003e1 × Silicone Joiner with Clamps\u003c\/li\u003e\n\u003cli\u003e3 × CNC Brackets\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Infinity Design","offers":[{"title":"Gloss","offer_id":49607478673546,"sku":"INF-A45-I-G","price":2268.0,"currency_code":"NZD","in_stock":false},{"title":"Matte","offer_id":49607478706314,"sku":"INF-A45-I-M","price":2268.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4599\/4122\/files\/ID070326-14.jpg?v=1782660953","url":"https:\/\/qjipdu-tf.myshopify.com\/products\/mercedes-w177-a45s-cla45s-gla45","provider":"SBX Performance","version":"1.0","type":"link"}
