Dinan's cold air intake reroutes the intake charge away from engine heat and into cooler, denser air from the front of the engine bay, reducing the charge temperature rise that gradually degrades power output as underhood temperatures climb during a performance drive.\u003c\/p\u003e\u003cp\u003eThe system uses a high-flow intake tube and performance filter to increase volumetric efficiency on the B48 engine, unlocking additional power across the mid to top RPM range. The cold air positioning compounds the gain beyond what a drop-in filter alone can achieve — both reduced restriction and lower charge temperatures work together to improve density at the throttle body.\u003c\/p\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e BMW G29 Z4 sDrive30i (B48)\u003cbr\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e Replaces factory airbox and intake path — no cutting or permanent modification\u003cbr\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e Cold air intake system with filter\u003cbr\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Not CARB exempt — not for sale or use in California.\u003cbr\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e D760-0066\u003cbr\u003e\u003cstrong\u003eProp 65:\u003c\/strong\u003e Yes\u003cbr\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Dinan","brand":"Dinan","offers":[{"title":"Default Title","offer_id":51564135743734,"sku":"DNND760-0066","price":571.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/5e8ce62d13f5f76e59241e8f616dfacfL.jpg?v=1788047412","url":"https:\/\/autotecknic.com\/products\/dinan-cold-air-intake-bmw-g29-z4-sdrive30i","provider":"AutoTecknic USA","version":"1.0","type":"link"}
